好久沒有寫CS端代碼，今天有空複習一下SOCKET。

功能說明：

1、服務端向用戶端發送資訊

2、用戶端向服務端發送資訊

效果如：

服務端代碼：

Socket serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);            IPEndPoint localPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 5000);            serverSocket.Bind(localPoint);            serverSocket.Listen(10);            new Thread(s =>            {                while (true)                {                    Socket clientSocket = ((Socket)s).Accept();                    clientSocket.Send(Encoding.ASCII.GetBytes("Server Say Hello"));                    clients.Add(clientSocket);                    new Thread((cS) =>                    {                        Socket myClientSocket = (Socket)clientSocket;                        while (true)                        {                            try                            {                                byte[] result = new byte[1024 * 1024];                                int receiveNumber = myClientSocket.Receive(result);                                string realMsg = string.Format("接收用戶端{0}訊息{1}\r\n", myClientSocket.RemoteEndPoint.ToString(), Encoding.Default.GetString(result, 0, receiveNumber));                                if (label1.InvokeRequired)                                {                                    label1.BeginInvoke(new Action<string>((msg) =>                                    {                                        label1.Text += msg;                                    }), realMsg);                                }                            }                            catch (Exception ex)                            {                                if (myClientSocket != null && myClientSocket.Connected)                                {                                    myClientSocket.Shutdown(SocketShutdown.Both);                                    myClientSocket.Close();                                }                            }                        }                    }) { IsBackground = true }.Start(clientSocket);                }            }) { IsBackground = true }.Start(serverSocket);

用戶端代碼：

            try            {                socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);                socket.Connect("127.0.0.1", 5000);                new Thread((s) =>                {                    Socket cS = (Socket)s;                    while (true)                    {                        byte[] byteMsg = new byte[1024 * 1024];                        int realResult = cS.Receive(byteMsg);                        string msg = Encoding.Default.GetString(byteMsg, 0, realResult);                        if (label1.InvokeRequired)                        {                            Action<string> a = (rm) =>                            {                                this.label1.Text += rm + "\r\n";                            };                            label1.BeginInvoke(a, msg);                        }                    }                }) { IsBackground = true }.Start(socket);                button1.Enabled = false;            }            catch (Exception ex)            {                button1.Enabled = true;            }
