Socket tcp服务端 代码示例

        private Socket serverS;
        public void ServerMethod(string server,string port,string textdata)
        {
            try
            {
                byte[]  data=new byte[1024];
                int recv;
                string host= server.Trim();
                IPAddress ip = IPAddress.Parse(host);
                int port1 = int.Parse(port.Trim());
                IPEndPoint ipe = new IPEndPoint(ip,port1);
                serverS = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
                serverS.Bind(ipe);//端口绑定
                serverS.Listen(10);//开始监听
                Socket clientC = serverS.Accept();//当有可用的客户端尝试连接时执行，并返回一个新的socket，用于服务端与客户端之间的通信
                IPEndPoint clientIp = (IPEndPoint)clientC.RemoteEndPoint;
                data = Encoding.ASCII.GetBytes(textdata);
                clientC.Send(data, data.Length, SocketFlags.None);
                while(true)
                {
                    data=new byte[1024];
                    recv = clientC.Receive(data);
                    if (recv==0)
                        break;
                    clientC.Send(data, recv,SocketFlags.None);
                }
                serverS.Close();
                clientC.Close();
            }
            catch (System.Exception ex)
            {
             throw ex;
            }
        }
