How to unblock ConnectNamedPipe and ReadFile? [C#]

[Shaitan00]

I have a class (NamedPipeManager) which has a thread (PipeThread) that waits for a NamedPipe connection using (ConnectNamedPipe) and then reads (ReadFile) - these are blocking calls (not-overlapped) - however there comes a point when I want to unblock them - for example when the calling class tries to stop the NamedPipeManager...

 

How can I interupt it? Using Thread.abort? Thread.interrupt? Is there a proper way to handle this?

Refer to the code below which illustrates my current situation

 

    main()

    {

        NamedPipeManager np = new NamedPipeManager();

            ... do stuff ...

        ... do stuff ...

        np.Stop();		// at this point I want to stop waiting on a connection

    }





    class NamedPipeManager

    {

    private Thread PipeThread;

    

    public NamedPipeManager

    {

        PipeThread = new Thread(new ThreadStart(ManagePipes));

        PipeThread.IsBackground = true;

        PipeThread.Name = "NamedPipe Manager";

        PipeThread.Start();

    }



    private void ManagePipes()

    {

        handle = CreateNamedPipe(..., PIPE_WAIT, ...);

        ConnectNamedPipe(handle, null);		// this is the BLOCKING call waiting for client connection

        

        ReadFile(....);				// this is the BLOCKING call to readfile after a connection has been established

        }





    public void Stop()

    {

        /// This is where I need to do my magic

        /// But somehow I need to stop PipeThread

        PipeThread.abort();		//?? my gut tells me this is bad

    }

    };

[/Code]

 

So, in function Stop() - how would I gracefully unblock the call to ConnectNamedPipe(...) or ReadFile(...)?

 

Any help would be appreciated.

Thanks,

I am assuming that CreateNamedPipe is just the Windows API being called - if so you should just use CloseHandle to close the pipe.
