c# socket連接和socket監聽

封裝的socket類

調用socket實現socket連接

SocketClient sc = new SocketClient("127.0.0.1", 60000);
sc.Connect();//進行連接
//然後可以收發數據

實現socket監聽服務

 		Socket acceptSocket = null;
 		Socket listenSocket = null;
 		/// <summary>
        /// 監聽請求
        /// </summary>
        /// <param name="port"></param>
        public int Listen(IPAddress ip, int port)
        {
            listenSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            listenSocket.Bind(new IPEndPoint(ip, port));
            listenSocket.Listen(100);
            try
            {
                    acceptSocket = listenSocket.Accept();
                    return 0;
            }
            catch (Exception ex)
            {
                    DestroySocket(acceptSocket);
                    return -1;
            }
       }
 		/// <summary>
        /// 銷燬Socket對象
        /// </summary>
        /// <param name="socket"></param>
        private static void DestroySocket(Socket socket)
        {
            if (socket.Connected)
            {
                socket.Shutdown(SocketShutdown.Both);
            }
            socket.Close();
        }
        //然後可以收發數據
        acceptSocket.Send(data);
        acceptSocket.Receive(data);
