The following example demonstrates how to obtain a RuntimeTypeHandle from a type or from an object, and how to turn the handle back into a type.

int x;
public:
int MyMethod()
{

}

// Get the RuntimeTypeHandle from an object.
RuntimeTypeHandle myRTHFromObject = Type::GetTypeHandle( myClass1 );
// Get the RuntimeTypeHandle from a type.
RuntimeTypeHandle myRTHFromType = MyClass1::typeid->TypeHandle;
Console::WriteLine( "\nmyRTHFromObject.Value: {0}", myRTHFromObject.Value );
Console::WriteLine( "myRTHFromObject.GetType(): {0}", myRTHFromObject.GetType() );
Console::WriteLine( "Get the type back from the handle..." );

Type::GetTypeFromHandle(myRTHFromObject) );
