I\'m using a NetworkStream & TcpClient to asynchronously receive data using BeginRead. I need to apply a time-out to this operation, such that after a specified amount o

It's the only way to do it, because when you're using an asynchronous operation, the thread that initiated the operation is off doing something else. The timeout is available with the synchronous version because the execution thread is blocked until the Read operation completes.

If you would have to use a background thread to cancel the operation, though, there wouldn't be much point to continuing to use the asynchronous Begin/End methods. If you're going to spin off a background thread, just perform a synchronous Read operation from the background thread, and then you can use the ReceiveTimeout.
