以上是服務端（server）的完整代碼。

用戶端（Client）的完整代碼如下：

namespace SocketClient  {      class Program      {          private static byte[] result = new byte[1024];          static void Main(string[] args)          {              //設定伺服器IP地址              IPAddress ip = IPAddress.Parse("127.0.0.1");              Socket clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);              try              {                  clientSocket.Connect(new IPEndPoint(ip, 8885)); //設定管理員IP與連接埠                  Console.WriteLine("串連伺服器成功");              }              catch              {                  Console.WriteLine("串連伺服器失敗，請按斷行符號鍵退出！");                  return;              }              //通過clientSocket接收資料              int receiveLength = clientSocket.Receive(result);              Console.WriteLine("接收伺服器訊息：{0}",Encoding.ASCII.GetString(result,0,receiveLength));              //通過 clientSocket 發送資料              for (int i = 0; i < 10; i++)              {                  try                  {                      Thread.Sleep(1000);    //等待1秒鐘                      string sendMessage = "client send Message Hellp" + DateTime.Now;                      clientSocket.Send(Encoding.ASCII.GetBytes(sendMessage));                      Console.WriteLine("向伺服器發送訊息：{0}" + sendMessage);                  }                  catch                  {                      clientSocket.Shutdown(SocketShutdown.Both);                      clientSocket.Close();                      break;                  }              }              Console.WriteLine("發送完畢，按斷行符號鍵退出");              Console.ReadLine();          }      }  }

編譯成功後，先運行 服務端（server），再運行用戶端（client）即可達到通訊效果。
