Returns the Type of the current instance.

[ VB ]
<Serializable>
<ClassInterface ( ClassInterfaceType.AutoDual ) >
Public Function GetType ( ) As Type

[ C# ]
[ Serializable ]
[ ClassInterface ( ClassInterfaceType.AutoDual ) ]
public Type GetType ( );

[ C++ ]
[ Serializable ]
[ ClassInterface ( ClassInterfaceType.AutoDual ) ]
public: Type* GetType ( );

[ JScript ]
public Serializable
   ClassInterface ( ClassInterfaceType.AutoDual )
function GetType ( ) : Type;

The Type instance that represents the exact runtime type of the current instance.

For two objects x and y that have identical runtime types, Object.ReferenceEquals ( x.GetType ( ),y.GetType ( ) ) returns true.

The Type object exposes the metadata associated with the class of the current Object.

[ C#, JScript ] The following code example demonstrates that GetType returns the runtime type of the current instance.

[ C# ]
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;

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


/*

This code produces the following output.

mybase: Type is MyBaseClass
myDerived: Type is MyDerivedClass
object o = myDerived: Type is MyDerivedClass
MyBaseClass b = myDerived: Type is MyDerivedClass

*/

[ JScript ]
import System

public class MyBaseClass extends Object {
}

public class MyDerivedClass extends MyBaseClass {
}

public class Test {

   public static function Main ( ) {
      var myBase : MyBaseClass = new MyBaseClass ( );
      var myDerived : MyDerivedClass = new MyDerivedClass ( );
      var o = myDerived;
      var b : MyBaseClass = myDerived;

      Response.Write ( "mybase: Type is {0}", myBase.GetType ( ) );
