Question

我是这个网站的新手，但很久以来一直在阅读。我对这个IP东西感到困惑，我是合理的程序员，但在IP方面很差。

我想用Android Server实现C＃客户端[Android设备遍布全球，所以首先要获取其IP地址]。

我已经在stackOverflow问题中编写了[复制]以下android代码并尝试使用它。

public static String getLocalIpAddress() {
        try {
            for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
                NetworkInterface intf = en.nextElement();
                for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
                    InetAddress inetAddress = enumIpAddr.nextElement();
                    if (!inetAddress.isLoopbackAddress()) {
                        String ip = Formatter.formatIpAddress(inetAddress.hashCode());
                        Log.i("IP", "***** IP="+ ip);
                        return ip;
                    }
                }
            }
        } catch (SocketException ex) {
            Log.e("EXCPTN", ex.toString());
        }
        return null;
}

问题1：它给了我一些Ip让我们说142.171.13.206，但是当我通过Google搜索检查我的IP时，我的ip＆＃39;从我的andoird决定，我完全得到新的IP [120.100.78.14]。我在做什么错？我在Wifi上运行，没有边缘没有3g或其他东西。

问题2：如果我有一个C＃客户端，我应该尝试连接哪个Android IP？因为我无法连接到Android服务器。

我的C＃客户端代码是这样的

    try
        {
            const int Port = 4321;
            TcpClient ourMagicClient = new TcpClient();

            //Connect to the server - change this IP address to match your server's IP!
            ourMagicClient.Connect("192.177.111.200", Port);

            //Use a NetworkStream object to send and/or receive some data
            NetworkStream ourStream = ourMagicClient.GetStream();

            //Let's set up some data!
            byte[] data = Encoding.ASCII.GetBytes("Plz recieve this msg!");

            //Everyone ready? Send that bad-boy!
            ourStream.Write(data, 0, data.Length); //Start at the 0'th position in our string and send until the end of the string, but we can stop there...
        }
        catch (Exception ex)
        {
            textBox1.Text = ex.ToString();
        }

最后这是运行4.4 Kitkat

的Android监听器的代码

private class SocketServerThread extends Thread {

      static final int SocketServerPORT = 4321;
      int count = 0;

      @Override
      public void run() {
       try {
        serverSocket = new ServerSocket(SocketServerPORT);
        MainActivity.this.runOnUiThread(new Runnable() {

         @Override
         public void run() {
          info.setText("I'm waiting here: "
            + serverSocket.getLocalPort());
             ;
         }
        });

        while (true) {
         Socket socket = serverSocket.accept();
         count++;
         message += "#" + count + " from " + socket.getInetAddress()
           + ":" + socket.getPort() + "\n";

         MainActivity.this.runOnUiThread(new Runnable() {

          @Override
          public void run() {
           msg.setText(message);
          }
         });

         SocketServerReplyThread socketServerReplyThread = new SocketServerReplyThread(
           socket, count);
         socketServerReplyThread.run();

        }
       } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
       }
      }

     }

private class SocketServerReplyThread extends Thread {

      private Socket hostThreadSocket;
      int cnt;

      SocketServerReplyThread(Socket socket, int c) {
       hostThreadSocket = socket;
       cnt = c;
      }

      @Override
      public void run() {
       OutputStream outputStream;
       String msgReply = "Hello from Android, you are #" + cnt;

       try {
        outputStream = hostThreadSocket.getOutputStream();
                 PrintStream printStream = new PrintStream(outputStream);
                 printStream.print(msgReply);
                 printStream.close();

        message += "replayed: " + msgReply + "\n";

        MainActivity.this.runOnUiThread(new Runnable() {

         @Override
         public void run() {
          msg.setText(message);
         }
        });

       } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        message += "Something wrong! " + e.toString() + "\n";
       }

       MainActivity.this.runOnUiThread(new Runnable() {

        @Override
        public void run() {
         msg.setText(message);
        }
       });
      }

     }

我有很多googles，也搜索过这个网站，但是我无法用Andoird服务器连接C＃客户端。 Plz帮助我解释代码在哪里修复。或者如果你有完全不同的工作代码，请与我分享。注意：感谢我复制上面代码的所有人[不幸的是我没有参考他们的网站]。 THX！
