Socket

客戶端

try
            {
                // TcpListener
                // TcpClient
                int port = 2000;
                string host = "127.0.0.1";
                IPAddress ip = IPAddress.Parse(host);
                IPEndPoint ipe = new IPEndPoint(ip, port);//把ip和端口轉化爲IPEndPoint實例
                Socket c = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);//建立一個Socket
                Console.WriteLine("Conneting");
                c.Connect(ipe);//鏈接到服務器
                string sendStr = "hello!This is a socket test";
                byte[] bs = Encoding.ASCII.GetBytes(sendStr);
                Console.WriteLine("Send Message");
                c.Send(bs, bs.Length, 0);//發送測試信息
                string recvStr = "";
                byte[] recvBytes = new byte[1024];
                int bytes;
                bytes = c.Receive(recvBytes, recvBytes.Length, 0);//從服務器端接受返回信息
                recvStr += Encoding.ASCII.GetString(recvBytes, 0, bytes);
                Console.WriteLine("Client Get Message:{0}", recvStr);//顯示服務器返回信息
                c.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();

　　服務端：

 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);//建立一個Socket類
                s.Bind(ipe);//綁定2000端口
                s.Listen(0);//開始監聽
                Console.WriteLine("Wait for connect");
                Socket temp = s.Accept();//爲新建鏈接建立新的Socket。
                Console.WriteLine("Get a connect");
                string recvStr = "";
                byte[] recvBytes = new byte[1024];
                int bytes;
                bytes = temp.Receive(recvBytes, recvBytes.Length, 0);//從客戶端接受信息
                recvStr += Encoding.ASCII.GetString(recvBytes, 0, bytes);
                Console.WriteLine("Server Get Message:{0}", recvStr);//把客戶端傳來的信息顯示出來
                string sendStr = "Ok!Client Send Message Sucessful!";
                byte[] bs = Encoding.ASCII.GetBytes(sendStr);
                temp.Send(bs, bs.Length, 0);//返回客戶端成功信息
                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();

上述代碼只是同步的Socket通訊，我也只是初學
