How to organize the completion of a separately launched thread in C #, if the socket is listening to the network in it?

Question

Multithreading

A separate thread is waiting for a message from the network. Everything works fine, but when you exit the program, the thread remains in memory.

// ...
while (Listening) {
  Socket ChatSocketHandler = ChatSocketListener.Accept();
// ...

Listening, of course, is changed to false to end processing, but it will only reach it on the next message from the network. And I need to interrupt ChatSocketListener.Accept() somehow.

Answer 1

Try setting the IsBackground = true property for this thread so that it becomes a background thread and does not prevent the process from terminating.

Answer 2

The socket must be closed in another thread, then Accept will fall with an exception, which you will process.

Answer 3

AcceptAsync?

Answer 4

Or, indeed, do it asynchronously through BeginAccept (http://msdn.microsoft.com/ru-ru/library/system.net.sockets.socket.beginaccept(v=vs.110).aspx), or, alternatively, create a client socket, and according to the action that you need (exit, as I understand it), make a connection and complete it ...

Answer 5

In principle, everything has already been stated above, I summarize:
There are two options as such:
1. Use APM and the BeginAccept method . The optimal choice. It can also be wrapped in TAP via wrapper and used with await.
2. Move the socket reference to the global space and leave the synchronous method in the thread. But when exiting, close or release the socket from another thread, and assign IsBackground to this thread (more details here ) so that even if the exit is incorrect, the thread does not hang.

Answer 6

Thread.Interrupt()?

Answer 7

Thank you all. I used the v_decadence (IsBackground = true) tip, since no processing is required when the thread ends:

Thread ListeningThread = new Thread(ListeningProcess);
ListeningThread.IsBackground = true;
ListeningThread.Start();
