Socket Disconnected Notification

[Vladimir Lushnikov]

Hi,

I know there exist asynchronous socket methods for connecting,
receiving/sending data and disconnecting - but how do you know when the
socket has been terminated - can you assign an event handler or a
delegate as to when the socket is disconnected - either gracefully from
remote or shut down by "brute force"?

In short, something like this:

MySocket.Close += new EventHandler(MySocket_OnClosed);


Anyone?

Unfortunately, no, there is no "direct" event for Closing.

When a socket is closed, you will get a receive notification. When you then
try to read from the socket, you will get 0 bytes received. THIS 0 bytes
received is the notification when a socket gets closed.

Yes.
There is no "direct" event for Closing
and if you worry about the socket is closed or not . You have to check it by
yourself.
