Use to wrap objects the marshaler should marshal as a VT_DISPATCH. This wrapper will force objects to be marshaled out as VT_DISPATCH. If the object does not support IDispatch then an exception will be thrown.

void MyMethod(Object o);
 Object o = new MyObject;
 MyMethod(o); //passes o as VT_UNKNOWN
 MyMethod(new DispatchWrapper(o)); //passes o as VT_DISPATCH

For more information on VT_DISPATCH, please see the existing documentation for VARENUM::VT_DISPATCH in the MSDN library.
