conditional beginReceive

Question

I am writing a client program that uses Sockets. I would like the client to receive asyncronously UNLESS it is expecting a response, in which case I would like to receive syncronously.

My current problem is that because I have to make a call to socket.BeginReceive which waits until there's data on the buffer, the async call always happens prior to the sync call..

How could I temporarily stop BeginReceive from executing? Is there a way to call EndReceive and then once I am done receiving syncronously, I can continue to receive asnycronously?

Answer 1

As far as I know there is no way to stop a BeginReceive short from shutting down the Socket. To do what you're trying to accomplish, you would need to move your calls to using completely synchronous, and put the calls you want to make asynchronously into separate threads. You'd then kill/pause the thread when you want to make an additional call. You could also set the ReceiveTimeout property to something low and have it continue looping until it sees a request to stop, like setting a class wide variable.

Simply for curiosity's sake, why do you want to make a synchronous call if you're already receiving asynchronously?
