智能设备和pc通过socket连接问题

Question

我用一台Gps手持机和pc通过socket连接
pc当主机，手持机当客户端
主机代码如下：            IPAddress ipAddress = Dns.GetHostAddresses(Dns.GetHostName())[0];
            IPEndPoint ipEndPoint = new IPEndPoint(ipAddress, 34567);
            ServerSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            ServerSocket.Bind(ipEndPoint );
            ListenThread = new Thread(ListenClientMessage);
            ListenThread.Start();
            ServerSocket.Listen(0);
            MessageBox.Show("服务器打开");
            Socket socket = ServerSocket.Accept();
            if (socket != null)
。。客户端代码如下：
 IPAddress ipAddress = IPAddress.Parse("192.168.0.105");
            IPEndPoint ipEndPoint = new IPEndPoint(ipAddress, 34567);
            ClientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            ClientSocket.Connect(ipEndPoint);//运行到这就提示 主机主动拒绝
            MessageBox.Show("连接服务器成功");
……每次只要 手持机通过数据线连在pc上
运行 连接 就提示 主机主动拒绝
我通过 ipconfig 可以获得 pc 和手持机的ip
并且可以ping 通
 
这个图和解决啊  求助啊

Answer 1

telnet 192.168.0.105  34567
试试通不通检查防火墙是否屏蔽了该端口

Answer 2

都拒绝你连接了你就应该看你pc的监听程序了
ip地址最好不要直接指定为第一个，或者你有多个网卡呢
listen（）多个连接看看
不行单步调试看看那句报错的

PC端主要代码，你可以参考下
        Socket s = null;
        TcpClient clientsocket;
        NetworkStream ns;
        TcpListener tcpListener = null;
        TcpClient tcpClient = null;
        private System.Threading.Thread pcThread = null;
        private static bool IsDone = true;
        if (tcpListener == null)
        {
              int port = 34567;
              IPEndPoint localEndPoint = new IPEndPoint(IPAddress.Any, port);              tcpListener = new TcpListener(localEndPoint);
              tcpListener.Start(10);              if (pcThread==null)
                     pcThread = new System.Threading.Thread(new System.Threading.ThreadStart(StartServer));
              pcThread.Start();
        }
       private void StartServer()
        {                
            while (IsDone)
            {
                string data = null;
                
                try
                {                   
                    tcpClient = tcpListener.AcceptTcpClient();
                    tcpClient.ReceiveTimeout = 240 * 1000;                   
                    
                    ns = tcpClient.GetStream();
                    byte[] recvBytes = new byte[1024];
                    int bytes = ns.Read(recvBytes, 0, recvBytes.Length);//从客户端接受信息  
                    if (bytes > 0)
                    {
                        data = Encoding.GetEncoding("GBK").GetString(recvBytes, 0, bytes);
                        //TO DO
// //返回响应
                        byte[] bSend = Encoding.GetEncoding("GBK").GetBytes("SUCCESS");
                        ns.Write(bSend, 0, bSend.Length);
                    }
                }
                catch (SocketException ex)
                {
                    //
                }
                catch (Exception ex)
                {
                   //
                }
                finally
                {
                    if (ns != null)
                    {
                        ns.Dispose();
                        ns.Close();
                        ns = null;
                    }
                    if (tcpClient != null)
                    {
                        tcpClient.Close();
                        tcpClient = null;
                    }
                }
                System.Threading.Thread.Sleep(500);
            }
        }

你的DNS  get的【0】个你看过是什么值么 ？我没错记错的是话IPv6吧 。这个就不对 。
