Question

I am having tasks which are running Work method

private void Work(Crawler crawler, PropertyBag propertyBag) {}

Now I want to stop all taks for 3 minutes and then continue with execution. I try with

Thread.Sleep but not working. Tasks still working. What is good solution to stop tasks for 3 minutes and then continue. Maybe locking and how to do it?

Answer 1

Thread.Sleep does not work because it sleeps the current thread.

If you create the threads by hand, not using TPL, then you hopefully have a list/array of the threads. You can use the Thread.Suspend and Thread.Resume methods.

foreach (var t in threads) t.Suspend();

// Then in 3 minutes.
foreach (var t in threads) t.Resume();

Note that Sleep/Resume are obsolete!

EDIT

Without having a list of threads, then you can use a ManualResetEvent. In your Work method do a .WaitOne() on it before attempting to any work.

On your main thread call .Reset when you want to sleep the tasks, and then in 3 minutes call .Set.
