c# - Socket.EndRead 0字节意味着断开连接？

Question

我想知道在我的 C# 异步套接字中，在 EndRead 调用中接收到 0 字节是否意味着服务器实际上已经断开了我们的连接？

我看到的许多例子都表明是这种情况，但我收到的断开连接频率比我预期的要高得多。

这段代码是否正确？或者 endResult <= 0 对连接状态没有任何意义？

private void socket_EndRead(IAsyncResult asyncResult)
{ 
  //Get the socket from the result state
  Socket socket = asyncResult.AsyncState as Socket;

  //End the read
  int endResult = Socket.EndRead(asyncResult);

  if (endResult > 0)
  {
    //Do something with the data here


  }
  else
  {
    //Server closed connection?  
  }
}

From the docs :

If the remote host shuts down the Socket connection and all available data has been received, the EndRead method completes immediately and returns zero bytes.

是的，零字节表示远程关闭。
