Thread: asynchronous function call

Hello everyone,


I am learning from,

http://msdn2.microsoft.com/en-us/lib...yc(VS.80).aspx

two simple questions,

1. For every degelate we defined (just a normal C# delegate, no special, and not special designed for asynchronous method call purpose), BeginInvoke and EndInvoke will be defined automatically for every delegate, right? (just looks like for every class we defined, toString, GetHashCode, etc. are defined automatically?)

2. What are the pros and cons compared with the pattern of using EndInvoke to wait for result and the pattern of using WaitHandle to wait for result. To my points, I think they function the same -- block the execution of current thread/method.


thanks in advance,
George

Waiting will lock the current invocation until it is complete allowing, upon completion of the current service request, subsequent processing in the current invocation.

Ending the invocation will close the current invoke upon completion of the current task and will have to be reopened for any other service requests.

Thanks TheRaven,


I do not quite understand your below comments, could you show some pseudo code please?

"Ending the invocation will close the current invoke upon completion of the current task and will have to be reopened for any other service requests."
