BeginReceive, and zero-sized packets

[JCarreon]

Hi all,

I am writing a small application that listens for any incoming message indefinitely, via BeginReceive. I did this by having the Receive callback function call the method that starts listening, after it processes the received data. (There probably is a better way to do this, but...)

My problem is, when the connection gets closed by the other side, I get a zero sized packet, and then I encounter an infinite loop of sorts.

Any ideas on how to circumvent this? Thanks in advance.

Welcome to the site. I believe you could check for zero packets and take an alternate action.

Thanks.

I have this block at the end of the callback

if (...) {.....}
else if (...) {...}
else if (sb.length ==0)
{
//Do nothing
}

StartListening();
}

What happens is, it does nothing, then starts listening again. Then immediately gets an empty packet, ignores it, starts listening, ad infinitum. This is what I'd like to avoid.
