Hi am trying to receives UDP pockets , but it is blocking in the
"Socket.Receive" can any one help me to find the problem...?

byte[] buffer = new byte[50];
Socket socket = new Socket(AddressFamily.InterNetwork,
SocketType.Dgram,ProtocolType.Udp);
socket.Bind(new IPEndPoint(IPAddress.Any, 5703));
int byterx = socket.Receive(buffer, 0, 1, SocketFlags.None);
Console.WriteLine(byterx.ToString());

Do you mean that it's blocking despite something sending a packet?
Socket.Receive is *meant* to block until it receives data.

jhon Socket.Receive is *meant* to block until it receives data ...but
am not able receive UDP packets ...can u check wats wrong in the code
or send me the code receive USP packets

Well, you haven't shown the code you're using to *send* the UDP
packets.

Could you post two short but complete programs, one which receives and
one which sends, which combined demonstrate the problem?

See http://pobox.com/~skeet/csharp/complete.html for what I mean by
that.

Thanks jon..but i don't have program to send UDP packets...actually am
trying to communicate with the RFID reader, reader will sends the UDP
packets properly..am able to see those packets in other network
tool..but am not able catch that using my program..

It shouldn't be too hard to come up with a program to send packets
though, and then we'd all be able to reproduce it.
