推荐答案

网络已断开仅当应用程序尝试从套接字读取数据/将数据写入套接字时，错误才会传播到套接字状态.
1.如果断开连接时客户端与服务器之间已建立的连接可用，则该连接将很容易传播，因为我们将在两端进行读/写操作.

2.如果未建立任何连接，则套接字状态将不会更改，直到我们尝试进行某些连接操作
请让我们知道您的问题情况以及您已解决了多大程度?

Network disconnected error is propagated to socket state only when the application try to read data from / write data to socket.
1. If an established connection is available between client and server at the time of disconnection then it will propagate easily as we will be doing a read / write operation at both ends.

2. If no connection is established then the socket state will not change until we attempt some connect operation
