Question

我有一个控制台应用程序，它等待客户端连接指定的套接字，然后接受客户端，开始提供数据，如果一段时间后客户端应用程序停止，分发器退出自己，但我会让分配器只是改变模式在监听对于客户端，当客户端连接丢失时，分发服务器才开始等待，但同时退出。

 static class Program
{
    static void Main()
    {
        Start()           
    }
}
private void Start()
    {            
        WaitForClientConnection();
       //waits till client connect
       StartReceive();
    }
private void WaitForClientConnection()
    {            
        _tcpSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
        _tcpSocket.Bind(new IPEndPoint(IPAddress.Parse("172.16.192.40"), 7000));
        _tcpSocket.Listen(100);
        _tcpClientAcceptSocket = _tcpSocket.Accept();           
    }
public void StartReceive()
    {           
        try
        {
            Console.WriteLine("Starting to receive data...");
            while (_tcpClient.Connected)
            {
               //sendind data to client

            }
            if (!_tcpClient.Connected)
            {
            // if client socket listener is stops somehow, I also close _tcpClient connection after that start to keep waiting for clients
            Console.WriteLine("Closing the connection...");
            _tcpClient.Close();   
            //here start(), and  WaitForClientConnection() are begin again(I realized and sure) however in WaitForClientConnection() function exits itself from application not wait for client
            Start();

            }
        }   
    }

可能是什么问题？

谢谢

第二次调用WaitForClientConnection（）时，尝试将新的侦听套接字绑定到172.16.192.40:7000。从第一次调用WaitForClientConnection（）开始，你已经有一个绑定到该地址的套接字。

尝试这样的事情：

private void CreateListener()
   {
   _tcpSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
   _tcpSocket.Bind(new IPEndPoint(IPAddress.Parse("172.16.192.40"), 7000));
   _tcpSocket.Listen(100);
    }
private void Start()
   {
   if (_tcpSocket == null)
      {
      CreateListener();
      }
   WaitForClientConnection();
   //waits till client connect
   StartReceive();
   }
private void WaitForClientConnection()
   {            
    _tcpClientAcceptSocket = _tcpSocket.Accept();           
   }

真的可以完全摆脱WaitForClientConnection，因为它现在只是一行代码。但那不是我写这个的方式;我只是想接近原始代码。

关键是你创建了一次监听套接字。当你接受对话时它不会消失。

我不知道这是否是唯一的问题。您应该捕获并报告异常，因此我们确切知道什么是终止该过程。
