如何处理NetworkStream.Write失败

Question

I have two applications a server and a client. I can send messages between the two as long as they are both running.

When I close the server and try to send a message with NetworkStream.Write i get an exception.

What would be the best way to handle this and notify the client that the server is down?

Answer 1

您可以在发送消息之前对服务器执行ping操作，如果ping操作失败，则通知用户并且不发送消息等。

Answer 2

Ping is a bad idea. The connection can go down between the ping and the actual message too.

As you yourself pointed out:

wrap the write in a try/catch and display a nice little message to the user.
