Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.


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.
