I am using a Timer to run an event periodically on a reasonably long interval (2 minutes). This is working fine. However I would like the event to fire immediately when the timer is created (instead of waiting 2 minutes).
Note that I can’t do this just by calling the method, since it takes some time to run and would block the application. I need the timer to fire as normal and run the event in a separate thread.
The best way I can think of doing this at the moment is subclassing the timer and creating a TriggerManually method that would do something like this:
- Turn auto reset off
- Set the interval to 1ms
- Enable the timer
This would trigger the elapsed event straight away, and I could put all the settings back to normal.
Seems a bit roundabout though. Is there a better way to do it?
Could you use a System.Threading.Timer instead ?
It has a constructor that lets you choose the interval as well as the delay (which can be set to 0 to begin immediately).
