服务端：
try { int port = 2000; string host = "127.0.0.1"; IPAddress ip = IPAddress.Parse(host); IPEndPoint ipe = new IPEndPoint(ip, port); Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);//创建一个Socket类 s.Bind(ipe);//绑定2000端口 s.Listen(0);//开始监听 Console.WriteLine("Wait for connect"); Socket temp = s.Accept();//为新建连接创建新的Socket。 Console.WriteLine("Get a connect"); string recvStr = ""; byte[] recvBytes = new byte[1024]; int bytes; bytes = temp.Receive(recvBytes, recvBytes.Length, 0);//从客户端接受信息 recvStr += Encoding.ASCII.GetString(recvBytes, 0, bytes); Console.WriteLine("Server Get Message:{0}", recvStr);//把客户端传来的信息显示出来 string sendStr = "Ok!Client Send Message Sucessful!"; byte[] bs = Encoding.ASCII.GetBytes(sendStr); temp.Send(bs, bs.Length, 0);//返回客户端成功信息 temp.Close(); s.Close(); } catch (ArgumentNullException e) { Console.WriteLine("ArgumentNullException: {0}", e); } catch (SocketException e) { Console.WriteLine("SocketException: {0}", e); } Console.WriteLine("Press Enter to Exit"); Console.ReadLine();
上述代码只是同步的Socket通信，我也只是初学
