c# async wait for event
Hi Experts,
I'd like to write an async method that does this:
while(true) {
await WaitForEventToBeSet(someEv
DoWork();
}
Somewhere else in the code:
someEvent.Set();
is this possible with async? What class can I use?
Thanks a lot!
Mike

Hi it_saige. That's not really what I'm looking for. The problem is that that will block. I wanted to have something that I could await. I think I'm diving a bit too deep on this one though. Not sure this is possible.
If you've used async and await, think of it this way, I call some function that loops and waits on an event, but does so asynchronously.

Thanks a lot for your explanation.
Sorry for taking so long to get back. I had a broken project for a while after a nuget update...
I wasn't awaiting the original call that calls this function. So that one runs off seemingly on its own thread (but not). I know there's never any other thread involved, but I was hoping somehow it would magically be able to wait for an event after "skipping over" the original call and getting to the stuff that will cause events to be set which would wake up my "thread" (without actually using a thread). This will work if I don't block.... So I guess I could just put a wait with a timeout. Would be totally cool to be able to do it with interrupts though.
Basically, the loop was just a provider that updates the UI asynchronously whenever events are fired off to it, and it also throttles how often it updates the UI by awaiting Task.Delay making sure a minimum time has passed before updating again... But I guess I've answered my own question here with the wait with timeout... Not what I was hoping for though. Maybe you'll have something better for me?

Nope - I cannot do this because I'm eating away at processing time... I guess I need a real thread unless you can see another way. I've been kind of overdoing it with async and await because of the simplicity but maybe this is just getting silly.
