protected System.Reflection.Binder()

Constructs a new instance of the System.Reflection.Binder class.

public System.Reflection.FieldInfo BindToField(System.Reflection.BindingFlags bindingAttr, System.Reflection.FieldInfo[] match, System.Object value, System.Globalization.CultureInfo culture)

Selects a field from the specified set of fields, based on the specified criteria.

Parameter bindingAttr: A bitwise combination of System.Reflection.BindingFlags values that control the binding process. For requirements, see the Behaviors section.

Parameter match: An array of System.Reflection.FieldInfo objects whose elements represent the set of fields that reflection has determined to be a possible match, typically because the fields have the correct member name.

Parameter value: An object of a type that is assignment-compatible with the type of the field being searched for. For example, if value is an instance of a class, the type of that instance can be assigned to the type of the field returned by this method. Fields in match that cannot be assigned to this value are eliminated from the search.

Parameter culture: The only defined value for this parameter is null .

Returns: A System.Reflection.FieldInfo instance that reflects the field that matches the specified criteria. It is not required that this instance be contained in match. If a suitable field is not found, returns null.

For the bindingAttr parameter, the caller is required to specify either System.Reflection.BindingFlags.Public or System.Reflection.BindingFlags.NonPublic, and either System.Reflection.BindingFlags.Instance or System.Reflection.BindingFlags.Static. If at least one value from each pair is not specified, this method is required to return null .

public System.Reflection.MethodBase BindToMethod(System.Reflection.BindingFlags bindingAttr, System.Reflection.MethodBase[] match, System.Object[]& args, System.Reflection.ParameterModifier[] modifiers, System.Globalization.CultureInfo culture, System.String[] names, System.Object& state)

Selects a method based on the specified criteria.

Parameter bindingAttr: A bitwise combination of System.Reflection.BindingFlags values that control the binding process. For requirements, see the Behaviors section.

Parameter match: An array of System.Reflection.MethodBase objects that represent the set of methods that Reflection has determined to be a possible match, typically because they have the correct member name.

Parameter args: An array of objects that represent the parameters passed in the method invocation. The types, values, and order of the elements of this array might be changed by this method to match the signature of the selected method.

Parameter modifiers: The only defined value for this parameter is null .

Parameter culture: The only defined value for this parameter is null .

Parameter names: A System.String array containing the names of methods to be searched.

Parameter state: A binder-provided System.Object that keeps track of parameter reordering. The state object is totally defined by the implementer of the System.Reflection.Binder class. This object is null if the binder does not reorder the argument array of the bound method.

Returns: A System.Reflection.MethodBase instance that reflects the method that matches to the specified criteria. It is not required that this instance be contained in match . If a suitable method is not found, returns null .

If state is not null, the system invokes System.Reflection.Binder.ReorderArgumentArray(System.Object[]@,System.Object) after this method returns. This allows a caller to map the argument array of a method back to the original form if the order has been altered by System.Reflection.Binder.BindToMethod(System.Reflection.BindingFlags,System.Reflection.MethodBase[],System.Object[]@,System.Reflection.ParameterModifier[],System.Globalization.CultureInfo,System.String[],System.Object@) . This is useful if ByRef arguments are in the argument array, because the caller can retrieve those arguments in their original order on return from this method. When arguments are passed by name (i.e., using named arguments), the binder reorders the argument array and that is what the caller sees. This method insures that the original order of the arguments is restored. For the bindingAttr parameter, the caller is required to specify either System.Reflection.BindingFlags.Public or System.Reflection.BindingFlags.NonPublic, and either System.Reflection.BindingFlags.Instance or System.Reflection.BindingFlags.Static. If at least one value from each pair is not specified, this method is required to return null . The System.Reflection.Binder.BindToMethod(System.Reflection.BindingFlags,System.Reflection.MethodBase[],System.Object[]@,System.Reflection.ParameterModifier[],System.Globalization.CultureInfo,System.String[],System.Object@) method is permitted to change the order of the argument array of a method call only if the binder returns, via the state parameter, a non-null opaque object that records the original order of the argument array. If, on return from System.Reflection.Binder.BindToMethod(System.Reflection.BindingFlags,System.Reflection.MethodBase[],System.Object[]@,System.Reflection.ParameterModifier[],System.Globalization.CultureInfo,System.String[],System.Object@), state is not null, the system calls System.Reflection.Binder.ReorderArgumentArray(System.Object[]@,System.Object) .

public System.Object ChangeType(System.Object value, System.Type type, System.Globalization.CultureInfo culture)

Converts the type of the specified object to the specified type.

Parameter value: The object to be converted to a new System.Type .

Parameter type: The System.Type to which value is converted.

Parameter culture: The only defined value for this parameter is null .

Returns: A new object of the type specified by type . The contents of this object are equal to those of value .

As described above. Implement this method to change the type of a member of a parameter array. Typically, it is recommended that implementations of this method perform only widening conversions. This method is used to change the type of a element in a parameter array to match the type required by the signature of a bound method.

public System.Void ReorderArgumentArray(System.Object[]& args, System.Object state)

Restores the specified set of parameters to their original order after a call to System.Reflection.Binder.BindToMethod(System.Reflection.BindingFlags,System.Reflection.MethodBase[],System.Object[]@,System.Reflection.ParameterModifier[],System.Globalization.CultureInfo,System.String[],System.Object@) .

Parameter args: An array of objects whose elements represent the parameters passed to the bound method in their original order.

Parameter state: A binder-provided opaque object that keeps track of parameter reordering. This object is the same object that was passed as the state parameter in the invocation of System.Reflection.Binder.BindToMethod(System.Reflection.BindingFlags,System.Reflection.MethodBase[],System.Object[]@,System.Reflection.ParameterModifier[],System.Globalization.CultureInfo,System.String[],System.Object@) that caused System.Reflection.Binder.ReorderArgumentArray(System.Object[]@,System.Object) to be called.

When a method call is bound to a method through reflection using System.Reflection.Binder.BindToMethod(System.Reflection.BindingFlags,System.Reflection.MethodBase[],System.Object[]@,System.Reflection.ParameterModifier[],System.Globalization.CultureInfo,System.String[],System.Object@) , the order, value, and type of the parameters in the original method call may be changed to match the signature of the bound method. The binder creates state as an opaque object that records the original order of the argument array. If, on return from System.Reflection.Binder.BindToMethod(System.Reflection.BindingFlags,System.Reflection.MethodBase[],System.Object[]@,System.Reflection.ParameterModifier[],System.Globalization.CultureInfo,System.String[],System.Object@), state is not null, the system calls System.Reflection.Binder.ReorderArgumentArray(System.Object[]@,System.Object). This allows a caller to map the argument array of a method back to the original form if the order had been altered by System.Reflection.Binder.BindToMethod(System.Reflection.BindingFlags,System.Reflection.MethodBase[],System.Object[]@,System.Reflection.ParameterModifier[],System.Globalization.CultureInfo,System.String[],System.Object@) . This is useful if ByRef arguments are in the argument array, because the caller can retrieve those arguments in their original order on return from this method. When arguments are passed by name (i.e., using named arguments), the binder reorders the argument array and that is what the caller sees. This method insures that the original order of the arguments is restored. state is required to be a non-null System.Object that tracks the original ordering of args if args is reordered by a call to System.Reflection.Binder.BindToMethod(System.Reflection.BindingFlags,System.Reflection.MethodBase[],System.Object[]@,System.Reflection.ParameterModifier[],System.Globalization.CultureInfo,System.String[],System.Object@) . This method is required to restore the elements of args to their original order, value, and System.Type Implement this method to insure that the parameters contained in args are returned to their original order, System.Type and value, after being used by a bound method. Use this method to insure that the parameters contained in args are returned to their original order, System.Type and value, after being used by a bound method.

public System.Reflection.MethodBase SelectMethod(System.Reflection.BindingFlags bindingAttr, System.Reflection.MethodBase[] match, System.Type[] types, System.Reflection.ParameterModifier[] modifiers)

Selects a method from the specified set of methods, based on the argument type.

Parameter bindingAttr: A bitwise combination of System.Reflection.BindingFlags values that control the binding process. For requirements, see the Behaviors section.

Parameter match: An array of System.Reflection.MethodBase objects that represent the set of methods that Reflection has determined to be a possible match, typically because they have the correct member name.

Parameter types: An array of System.Type objects that represent the values used to locate a matching method.

Parameter modifiers: The only defined value for this parameter is null .

Returns: A System.Reflection.MethodBase instance that reflects the method that is matched to the specified criteria. It is not required that this instance be contained in match . If a suitable method is not found, returns null .

For the bindingAttr parameter, the caller is required to specify either System.Reflection.BindingFlags.Public or System.Reflection.BindingFlags.NonPublic, and either System.Reflection.BindingFlags.Instance or System.Reflection.BindingFlags.Static. If at least one value from each pair is not specified, this method is required to return null .

public System.Reflection.PropertyInfo SelectProperty(System.Reflection.BindingFlags bindingAttr, System.Reflection.PropertyInfo[] match, System.Type returnType, System.Type[] indexes, System.Reflection.ParameterModifier[] modifiers)

Selects a property from the specified set of properties, based on the specified criteria.

Parameter bindingAttr: A bitwise combination of System.Reflection.BindingFlags values that control the binding process. For requirements, see the Behaviors section.

Parameter match: An array of System.Reflection.PropertyInfo objects that represent the set of properties that Reflection has determined to be a possible match, typically because they have the correct member name.

Parameter returnType: The System.Type of the property being searched for.

Parameter indexes: An array of System.Type objects that represent the index types of the property being searched for. Use this parameter for index properties such as the indexer for a class.

Parameter modifiers: The only defined value for this parameter is null .

Returns: A System.Reflection.PropertyInfo instance that reflects the property that matches the specified criteria. It is not required that this instance be contained in match . If a suitable property is not found, returns null .

For the bindingAttr parameter, the caller is required to specify either System.Reflection.BindingFlags.Public or System.Reflection.BindingFlags.NonPublic, and either System.Reflection.BindingFlags.Instance or System.Reflection.BindingFlags.Static. If at least one value from each pair is not specified, this method is required to return null .

public virtual System.Boolean Equals(System.Object obj)

Determines whether the specified System.Object is equal to the current instance.

Parameter obj: The System.Object to compare with the current instance.

Returns: true if obj is equal to the current instance; otherwise, false.

The statements listed below are required to be true for all implementations of the System.Object.Equals(System.Object) method. In the list, x, y, and z represent non-null object references. See System.Object.GetHashCode for additional required behaviors pertaining to the System.Object.Equals(System.Object) method. Implementations of System.Object.Equals(System.Object) should not throw exceptions. The System.Object.Equals(System.Object) method tests for referential equality , which means that System.Object.Equals(System.Object) returns true if the specified instance of Object and the current instance are the same instance; otherwise, it returns false . An implementation of the System.Object.Equals(System.Object) method is shown in the following C# code: public virtual bool Equals(Object obj) { return this == obj; } For some kinds of objects, it is desirable to have System.Object.Equals(System.Object) test for value equality instead of referential equality. Such implementations of Equals return true if the two objects have the same "value", even if they are not the same instance. The definition of what constitutes an object's "value" is up to the implementer of the type, but it is typically some or all of the data stored in the instance variables of the object. For example, the value of a System.String is based on the characters of the string; the Equals method of the System.String class returns true for any two string instances that contain exactly the same characters in the same order. When the Equals method of a base class provides value equality, an override of Equals in a class derived from that base class should invoke the inherited implementation of Equals . It is recommended (but not required) that types overriding System.Object.Equals(System.Object) also override System.Object.GetHashCode. Hashtables cannot be relied on to work correctly if this recommendation is not followed. If your programming language supports operator overloading, and if you choose to overload the equality operator for a given type, that type should override the Equals method. Such implementations of the Equals method should return the same results as the equality operator. Following this guideline will help ensure that class library code using Equals (such as System.Collections.ArrayList and System.Collections.Hashtable ) behaves in a manner that is consistent with the way the equality operator is used by application code. If you are implementing a value type, you should follow these guidelines: For reference types, the guidelines are as follows: If you implement System.IComparable on a given type, you should override Equals on that type. The System.Object.Equals(System.Object) method is called by methods in collections classes that perform search operations, including the System.Array.IndexOf(System.Array,System.Object) method and the System.Collections.ArrayList.Contains(System.Object) method.

using System;
class MyClass {
   static void Main() {
      Object obj1 = new Object();
      Object obj2 = new Object();

   }

public static System.Boolean Equals(System.Object objA, System.Object objB)

Determines whether two object references are equal.

Parameter objA: First object to compare.

Parameter objB: Second object to compare.

Returns: true if one or more of the following statements is true: otherwise returns false.

This static method checks for null references before it calls objA.Equals(objB ) and returns false if either objA or objB is null. If the Equals(object obj) implementation throws an exception, this method throws an exception.

using System;

public class MyClass {
   public static void Main() {
   string s1 = "Tom";
   string s2 = "Carol";
   Console.WriteLine("Object.Equals(\"{0}\", \"{1}\") => {2}", 
      s1, s2, Object.Equals(s1, s2));

   s1 = "Tom";
   s2 = "Tom";
   Console.WriteLine("Object.Equals(\"{0}\", \"{1}\") => {2}", 
      s1, s2, Object.Equals(s1, s2));

   s1 = null;
   s2 = "Tom";
   Console.WriteLine("Object.Equals(null, \"{1}\") => {2}",
       s1, s2, Object.Equals(s1, s2));

   s1 = "Carol";
   s2 = null;
   Console.WriteLine("Object.Equals(\"{0}\", null) => {2}", 
       s1, s2, Object.Equals(s1, s2));

   s1 = null;

       s1, s2, Object.Equals(s1, s2));
   }
}
   

public System.Void Finalize()

Allows a System.Object to perform cleanup operations before the memory allocated for the System.Object is automatically reclaimed.

During execution, System.Object.Finalize is automatically called after an object becomes inaccessible, unless the object has been exempted from finalization by a call to System.GC.SuppressFinalize(System.Object). During shutdown of an application domain, System.Object.Finalize is automatically called on objects that are not exempt from finalization, even those that are still accessible. System.Object.Finalize is automatically called only once on a given instance, unless the object is re-registered using a mechanism such as System.GC.ReRegisterForFinalize(System.Object) and System.GC.SuppressFinalize(System.Object) has not been subsequently called. Conforming implementations of the CLI are required to make every effort to ensure that for every object that has not been exempted from finalization, the System.Object.Finalize method is called after the object becomes inaccessible. However, there may be some circumstances under which Finalize is not called. Conforming CLI implementations are required to explicitly specify the conditions under which Finalize is not guaranteed to be called. For example, Finalize might not be guaranteed to be called in the event of equipment failure, power failure, or other catastrophic system failures. In addition to System.GC.ReRegisterForFinalize(System.Object) and System.GC.SuppressFinalize(System.Object), conforming implementations of the CLI are allowed to provide other mechanisms that affect the behavior of System.Object.Finalize . Any mechanisms provided are required to be specified by the CLI implementation. The order in which the Finalize methods of two objects are run is unspecified, even if one object refers to the other. The thread on which Finalize is run is unspecified. Every implementation of System.Object.Finalize in a derived type is required to call its base type's implementation of Finalize . This is the only case in which application code calls System.Object.Finalize . The System.Object.Finalize implementation does nothing. A type should implement Finalize when it uses unmanaged resources such as file handles or database connections that must be released when the managed object that uses them is reclaimed. Because Finalize methods may be invoked in any order (including from multiple threads), synchronization may be necessary if the Finalize method may interact with other objects, whether accessible or not. Furthermore, since the order in which Finalize is called is unspecified, implementers of Finalize (or of destructors implemented through overriding Finalize) must take care to correctly handle references to other objects, as their Finalize method may already have been invoked. In general, referenced objects should not be considered valid during finalization. See the System.IDisposable interface for an alternate means of disposing of resources. For C# developers: Destructors are the C# mechanism for performing cleanup operations. Destructors provide appropriate safeguards, such as automatically calling the base type's destructor. In C# code, System.Object.Finalize cannot be called or overridden.

public virtual System.Int32 GetHashCode()

Generates a hash code for the current instance.

Returns: A System.Int32 containing the hash code for the current instance.

System.Object.GetHashCode serves as a hash function for a specific type. A hash function is used to quickly generate a number (a hash code) corresponding to the value of an object. Hash functions are used with hashtables. A good hash function algorithm rarely generates hash codes that collide. For more information about hash functions, see The Art of Computer Programming , Vol. 3, by Donald E. Knuth. All implementations of System.Object.GetHashCode are required to ensure that for any two object references x and y, if x.Equals(y) == true, then x.GetHashCode() == y.GetHashCode(). Hash codes generated by System.Object.GetHashCode need not be unique. Implementations of System.Object.GetHashCode are not permitted to throw exceptions. The System.Object.GetHashCode implementation attempts to produce a unique hash code for every object, but the hash codes generated by this method are not guaranteed to be unique. Therefore, System.Object.GetHashCode may generate the same hash code for two different instances. It is recommended (but not required) that types overriding System.Object.GetHashCode also override System.Object.Equals(System.Object) . Hashtables cannot be relied on to work correctly if this recommendation is not followed. Use this method to obtain the hash code of an object. Hash codes should not be persisted (i.e. in a database or file) as they are allowed to change from run to run.

 }
}

public System.Type GetType()

Gets the type of the current instance.

Returns: The instance of System.Type that represents the run-time type (the exact type) of the current instance.

For two objects x and y that have identical run-time types, System.Object.ReferenceEquals(System.Object,System.Object)(x.GetType(),y.GetType()) returns true .

using System;
public class MyBaseClass: Object {
}
public class MyDerivedClass: MyBaseClass {
}
public class Test {
   public static void Main() {
   MyBaseClass myBase = new MyBaseClass();
   MyDerivedClass myDerived = new MyDerivedClass();

   object o = myDerived;
   MyBaseClass b = myDerived;

   Console.WriteLine("mybase: Type is {0}", myBase.GetType());
   Console.WriteLine("myDerived: Type is {0}", myDerived.GetType());
   Console.WriteLine("object o = myDerived: Type is {0}", o.GetType());
   Console.WriteLine("MyBaseClass b = myDerived: Type is {0}", b.GetType());
   }
}

protected System.Object MemberwiseClone()

Creates a shallow copy of the current instance.

Returns: A shallow copy of the current instance. The run-time type (the exact type) of the returned object is the same as the run-time type of the object that was copied.

System.Object.MemberwiseClone creates a new instance of the same type as the current instance and then copies each of the object's non-static fields in a manner that depends on whether the field is a value type or a reference type. If the field is a value type, a bit-by-bit copy of all the field's bits is performed. If the field is a reference type, only the reference is copied. The algorithm for performing a shallow copy is as follows (in pseudo-code): for each instance field f in this instance if (f is a value type) bitwise copy the field if (f is a reference type) copy the reference end for loop This mechanism is referred to as a shallow copy because it copies rather than clones the non-static fields. Because System.Object.MemberwiseClone implements the above algorithm, for any object, a, the following statements are required to be true: System.Object.MemberwiseClone does not call any of the type's constructors. If System.Object.Equals(System.Object) has been overridden, a.MemberwiseClone().Equals(a) might return false . For an alternate copying mechanism, see System.ICloneable . System.Object.MemberwiseClone is protected (rather than public) to ensure that from verifiable code it is only possible to clone objects of the same class as the one performing the operation (or one of its subclasses). Although cloning an object does not directly open security holes, it does allow an object to be created without running any of its constructors. Since these constructors may establish important invariants, objects created by cloning may not have these invariants established, and this may lead to incorrect program behavior. For example, a constructor might add the new object to a linked list of all objects of this class, and cloning the object would not add the new object to that list -- thus operations that relied on the list to locate all instances would fail to notice the cloned object. By making the method protected, only objects of the same class (or a subclass) can produce a clone and implementers of those classes are (presumably) aware of the appropriate invariants and can arrange for them to be true without necessarily calling a constructor.

using System;
class MyBaseClass {
   public static string CompanyName = "My Company";

   m1.age = 42;
   m1.name = "Sam";

public static System.Boolean ReferenceEquals(System.Object objA, System.Object objB)

Determines whether two object references are identical.

Parameter objA: First object to compare.

Parameter objB: Second object to compare.

Returns: True if a and b refer to the same object or are both null references; otherwise, false.

This static method provides a way to compare two objects for reference equality. It does not call any user-defined code, including overrides of System.Object.Equals(System.Object) .

using System;
class MyClass {
   static void Main() {
   object o = null;
   object p = null;
   object q = new Object();
   Console.WriteLine(Object.ReferenceEquals(o, p));
   p = q;
   Console.WriteLine(Object.ReferenceEquals(p, q));
   Console.WriteLine(Object.ReferenceEquals(o, p));
   }
}
   

public virtual System.String ToString()

Creates and returns a System.String representation of the current instance.

Returns: A System.String representation of the current instance.

System.Object.ToString returns a string whose content is intended to be understood by humans. Where the object contains culture-sensitive data, the string representation returned by System.Object.ToString takes into account the current system culture. For example, for an instance of the System.Double class whose value is zero, the implementation of System.Double.ToString might return "0.00" or "0,00" depending on the current UI culture. Although there are no exact requirements for the format of the returned string, it should as much as possible reflect the value of the object as perceived by the user. System.Object.ToString is equivalent to calling System.Object.GetType to obtain the System.Type object for the current instance and then returning the result of calling the System.Object.ToString implementation for that type. The value returned includes the full name of the type. It is recommended, but not required, that System.Object.ToString be overridden in a derived class to return values that are meaningful for that type. For example, the base data types, such as System.Int32, implement System.Object.ToString so that it returns the string form of the value the object represents. Subclasses that require more control over the formatting of strings than System.Object.ToString provides should implement System.IFormattable, whose System.Object.ToString method uses the culture of the current thread.

using System;

class MyClass {
   static void Main() {
      object o = new object();
      Console.WriteLine (o.ToString());
   }
}
