C# - Tcp Server & Client

קוד סרבר שמחכה עד שקליינט יתחבר, ואז מקבל הודעות ומחזיר אותן אל הקליינט:

TCP Server:
void server_foo(){ int port = 9050; int recv; byte[]data = new byte[1024]; IPEndPoint ipep = new IPEndPoint(IPAdress.Any, port); Socket newsock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); newsock.Bind(ipep); newsock.Listen(10); Console.WriteLine("waiting for client..."); Socket client = newsoc.Accept(); IPEndPoint clientep = (IPEndPoint )client.RemoteEndPoint; Console.WriteLine($"Connected with {clientep.Address} at port {clientep.Port}"); data = Encoding.ASCII.GetBytes("[CONNECTED TO SERVER]"); client.Send(data, data.Length, SocketFlag.None); while (true) { try { data = new byte[1024]; recv = client.Receive(data); Console.WriteLine(Encoding.ASCII.GetString(data, 0, recv)); if(recv == 0) break; // 0 == exit client.Send(data, recv, SocketFlags.None); } catch (Exception ex) { Console.WriteLine(ex.Message); Console.ReadLine(); break; } finally { client.Close(); newsock.Close(); } } Console.WriteLine($"Disconnected from {clientep.Address}:{clientep.Port}"); }

קוד קליינט שמנסה כל 5 שניות להתחבר:
