Question

I have a method which is running very long. I want to be able to stop, pause and continue the execution of that method.I viewed this question and the answer is nice, but I want to use more general library like TPL.
TPL has a cancellation mechanism, but I can’t find pause/continue functionality.

edit

Thanks for all answers. But the problem is that I don’t write that “long running” method, I just call that method.

Answer 1

The easiest way to implement this is with a BackgroundWorker control. It supports cancel and progress reporting.

Oh, I see. Well, there is no “clean” way of pausing and resuming a method that you didn’t write, unless you want to suspend the thread. And, if the method isn’t thread-safe, you might be out of luck. http://msdn.microsoft.com/en-us/library/d00bd51t.aspx
