检测互联网断开时的插座断开。 [英] Detect socket disconnection on internet disconnection.

问题描述

为重复问题而道歉。

我已经尝试过给出的解决方案，在我的情况下不起作用。

对于断开连接我已经处理了套接字异常，0收到的用于处理断开连接的字节。

这在服务器关闭，局域网断开的情况下非常有效。

但是当互联网断开连接时，套接字不会立即断开连接。

当我在套接字上发送一些数据后断开互联网连接时，那个时间套接字

断开连接。

如果互联网断开，我如何立即检测到套接字断开。

我试过Socket.Poll（）。这不行。

我的代码是用c＃.net

Apologize for repeating question.
I have already tried the solution given, doesn't work in my case.
For disconnection i have already handled socket exception , 0 bytes received for handling disconnection.
This works perfectly in case of server shutdown , lan disconnection.
But when internet disconnects, socket does not disconnects immediately.
After internet disconnection when i sent some data on socket, that time socket
get disconnected.
How do i immediately detect socket disconnection in case of internet disconnection.
I have tried Socket.Poll().This doesn't works.
My code is written in c# .net

推荐答案

你不能。在尝试向服务器发送内容超时并失败之前，不会做出决定。

You can't. The determination isn't made until an attempt to send something to the server times out and fails.
