Question

我尝试从android连接到c＃ - 服务器。我的电脑ip地址是：“10.100.102.7”; 我测试了android客户端和服务器应用程序，它们运行良好，当我尝试从android连接到C＃时，问题就开始了 - 服务器

C＃：

IPEndPoint localEndPoint = new IPEndPoint(IPAddress.Parse("10.100.102.7"), 6000);/
listener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
listener.Bind(localEndPoint);
listener.Listen(100);
Receiver = listener.Accept();

Java：

private Socket Sender_Socket;

private static final int SERVERPORT = 6000;

private static final String SERVER_IP = "10.100.102.7";

class Connect_To_Server implements Runnable
 {
  @Override
  public void run()
   {
    try
     {
      InetAddress serverAddr = InetAddress.getByName(SERVER_IP);
      Sender_Socket = new Socket(serverAddr, SERVERPORT);
     }
    catch (UnknownHostException e1)
     {
      e1.printStackTrace();
     }
    catch (IOException e1)
     {
      e1.printStackTrace();
     }
   }
 }

在C＃中 - 它在“Receiver = listener.Accept（）;”上停止在java（android）中 - 它停在“Sender_Socket = new Socket（serverAddr，SERVERPORT）;” 它应该是java socket函数中的问题 - 需要另一个函数来连接到C＃ - server。

Answer 1

你需要实际发送一些东西，你在Java类中所做的一切都是检索InetAddress并打开一个套接字？

你需要实际做一些像发送数据包......

首先阅读：

http://developer.android.com/reference/java/net/Socket.html

然后逐步完成以下一些示例： http://examples.javacodegeeks.com/android/core/socket-core/android-socket-example/

此外，您应该确保添加另一个（这次是通用的）错误捕获器，因为您处理的那些异常不是使用套接字/连接时可能发生的唯一两个。

byte[] byData = System.Text.Encoding.ASCII.GetBytes("Connected");
listener.Send(byData);
waitForData(listener);


void waitForData(SocketState state)
    {
        try
        {
            state.Socket.BeginReceive(state.DataBuffer, 0, state.DataBuffer.Length, SocketFlags.None, new AsyncCallback(readDataCallback), state);
        }
        catch (SocketException se)
        {
            //Socket has been closed  
            //Close/dispose of socket
        }
    }

    public void readDataCallback(IAsyncResult ar)
    {
        SocketState state = (SocketState)ar.AsyncState;
        try
        {
            // Read data from the client socket.
            int iRx = state.Socket.EndReceive(ar);

            //Handle Data....

            waitForData(state);
        }
        catch (ObjectDisposedException)
        {
            //Socket has been closed  
            //Close/dispose of socket
        }
        catch (SocketException se)
        {
            //Socket exception
            //Close/dispose of socket
        }
    }
