简单的SOCKET通信问题

Question

1、实现一个简单的SOCKET通信程序
启动服务端，由客户端发起连接，连通后向服务端发送连通时间
2、问题（如代码）：
这里ServerIP改成127.0.0.1，客户端程序是可以执行与服务端的通信的，但如果改成我的机器IP时，就不通过，问题停留在“ int Bytes = Strm.Read(inputBuffer, 0, inputBuffer.Length);”这句话上。
3、代码：（客户端）
            TcpClient client = new TcpClient();
            client.Connect(new IPEndPoint(ServerIP, 139));
            //获取流

            Stream Strm;
            try
            {
                Strm = client.GetStream();
            }
            catch (InvalidOperationException)
            {
                label3.Text = String.Format("Cannot Connect to Server :{0}", ServerTextBox.Text);
                return;
            }
            catch (SocketException exc)
            {
                StringBuilder strB = new StringBuilder("");
                strB.Append(String.Format("Cannot connect to Server :{0}\r\n", ServerTextBox.Text));
                strB.Append(exc.Message + "\r\r");
                strB.Append("Socket Error Code:" + exc.ErrorCode.ToString());
                label3.Text = strB.ToString();
                return;
            }
            //读取流,并转ASCII码
            Byte[] inputBuffer = new Byte[128];
            int Bytes = Strm.Read(inputBuffer, 0, inputBuffer.Length);

谢谢！！

Answer 1

把服务器端的监听IP地址改成0.0.0.0即IPAddress.Any
Any 字段指示 Socket 实例应侦听所有网络接口上的客户端活动

Answer 2

服务端程序如下：请问你说的IpAddress.Any放在哪些 ,谢谢
               TcpListener tcpServer = new TcpListener(139);
                tcpServer.Start();

                //Report所在位置
                IPHostEntry thisHost = Dns.Resolve(Dns.GetHostName());
                Console.WriteLine("Host:{0} listening on : {1},port: {2}", thisHost.HostName, thisHost.AddressList[0].ToString(), 139);
                Console.WriteLine("Waiting for the connecting...");

                //接收阻塞,直到有人连接
                TcpClient clientConn = tcpServer.AcceptTcpClient();
                //发回包括时间在内的消息
                Response = "Server Response sent at  " + DateTime.Now.ToLongTimeString();

                //将字符串转换成字符数组,然后发送该数组
                byte[] byteResponse = Encoding.ASCII.GetBytes(Response.ToCharArray());
                clientConn.GetStream().Write(byteResponse, 0, byteResponse.Length);
                clientConn.Close();

Answer 3

这是我以前写的：通讯没有出过我问题，

//设置编号方式
            Encoding myEncoding = Encoding.GetEncoding("GB2312");
            //发送消息
            int port = 10000;//端口号
            string host = "192.168.0.0";//ip地址
            IPAddress ip = IPAddress.Parse(host);
            IPEndPoint ipe = new IPEndPoint(ip, port);//把ip和端口转化为IPEndPoint实例
            Socket SockSend = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);//创建一个Socket
            SockSend.Connect(ipe);//连接到服务器
            byte[] SendString = myEncoding.GetBytes(sendStr);
            SockSend.Send(SendString, SendString.Length, 0);//发送消息
            //接收消息
            string recvStr = "";
            byte[] recvBytes = new byte[1024];
            int bytes;
            bytes = SockSend.Receive(recvBytes, recvBytes.Length, 0);//从服务器端接受返回信息
            recvStr += myEncoding.GetString(recvBytes, 0, bytes);
