Pausing and resuming BackgroundWorker

I've been wondering is there any way in which we can move BackgroundWorker to sleep and resume it again just like thread. I've searched in many forums in vain. None of them show any method which would do that. I checked Microsoft documentation and found out there isn't any predefined methods.

I know the workarounds by using resetEvents. Just asking for any other possible and much easier way.

From within your DoWork handler, you can call Thread.Sleep() whenever you want. If you want, from the GUI, to be able to signal the worker to pause, set up a concurrent queue, feed your sleep requests into it from the GUI thread, and have your DoWork handler check the queue periodically, pausing as requested.

(If you want to pause the BackgroundWorker until signaled again rather than for a certain period of time, you can do that in a similar way--just periodically check the queue for a "restart" command and sleep a few milliseconds before checking again.)
