Are you calling the ShutDown() method before you make a call to Close() ?

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia My Website | Ask smart questions

Dear Sid, I am using this piece of code in thread.It tells me when client is connected and send data to me. Socket listener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); IPEndPoint endpoint = new IPEndPoint(IPAddress.Any, 8001); listener.Bind(endpoint); listener.Blocking = true; listener.Listen(0); Socket objSock = listener.Accept(); objSock.Receive(ReceiveData); objSock.Shutdown(SocketShutdown.Both); listener.Close();
