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);

public void DoWrap()
    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.
