sockets-android客户端到c#服务器连接

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#Server时，问题就开始了

C#：

爪哇：

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，它在“Sender_Socket=newsocket（serverAddr，SERVERPORT）；”上停止

这应该是java socket函数中的问题-需要另一个函数来连接到C#-服务器。

您需要实际发送一些东西，您在java类中所做的一切就是检索InetAddress并打开一个套接字

你实际上需要做一些事情，比如发送一个包

从阅读以下内容开始：

然后通过以下几个例子进行练习：

此外，您还应该确保添加另一个（这次是通用的）错误捕捉器，因为在使用套接字/连接时，您处理的异常并不是唯一两个可能发生的异常

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
        }
    }

我只擅长C#

我关掉了防火墙，现在他们可以连接了

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
        }
    }
