The handle for the current Type.

Exception Condition
NotSupportedException

The .NET Compact Framework does not currently support this property.

TypeHandle encapsulates a pointer to an internal data structure that represents the type. This handle is unique during the process lifetime. The handle is valid only in the application domain in which it was obtained.

The following example returns the handle of the corresponding type and passes the handle to a method that gets the type from the handle and displays it.

using namespace System;
using namespace System::Reflection;
ref class MyClass
{
public:
   int myField;
};

void DisplayTypeHandle( RuntimeTypeHandle myTypeHandle )
{

   // Get the type from the handle.
   Type^ myType = Type::GetTypeFromHandle( myTypeHandle );

   // Display the type.
   Console::WriteLine( "\nDisplaying the type from the handle:\n" );
   Console::WriteLine( "The type is {0}.", myType );
}

int main()
{
   try
   {
      MyClass^ myClass = gcnew MyClass;

      // Get the type of MyClass.
      Type^ myClassType = myClass->GetType();

      // Get the runtime handle of MyClass.
      RuntimeTypeHandle myClassHandle = myClassType->TypeHandle;
      DisplayTypeHandle( myClassHandle );
   }
   catch ( Exception^ e ) 
   {
      Console::WriteLine( "Exception: {0}", e->Message );
   }

}
