C#笔记（9）Socket长连接

新建类SocketIO.cs

class SocketIO
    {
        public static Socket client;
        public static Thread thread;
        public static IPAddress ip = new IPAddress(new byte[] {IP号, IP号, IP号, IP号 });
        public static IPEndPoint point = new IPEndPoint(ip, Convert.ToInt32(端口号));
        public static System.Windows.Forms.Timer heartBeat;
        public static void startSocket()
        {
            client = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            client.Connect(point);
            thread = new Thread(new ThreadStart(ReceiveMsg));
            thread.IsBackground = true;
            thread.Start();
        }
        public static void ReceiveMsg()
        {
            while (true)
            {
                byte[] buffer = new byte[1024 * 1024];
                if (client.Receive(buffer) != 0)
                {
                    String json = Encoding.UTF8.GetString(buffer);//将byte转换成String
                    json=json.Replace("\0", "");//去掉多余的\0
                    //接收数据后做的事情
                }
            }
        }
        public static void SendMsg(String msg)
        {
            //客户端给服务器发消息
            if (client != null)
            {
                byte[] buffer = Encoding.UTF8.GetBytes(msg);
                client.Send(buffer);
            }
        }
    }
