c# - How to stop a timer Immediately

Question

I have a System.Timers.Timer with 100 interval. my question is that if I set enable = false in timer, is current working process in timer method stop immediately? or after method finished.

private void watchTags(object obj, ElapsedEventArgs handler)
    {
        for(int i=0 ; i<10000;i++){
            // some works
        }
    }
private void stop_button(){
    watcher.Enabled = false;
}

is my loop immediately stop or after finish?

so google doesn't work on your end.. ?? come on now... for example here is a previous posting http://stackoverflow.com/questions/4563704/c-sharp-how-do-you-stop-a-timer — MethodMan, Jul 02 '15 at 04:38
@MethodMan I'm already know about that. my question is when process terminate. after finish current method or as soon as enable set to false — nariman amani, Jul 02 '15 at 04:43
so explain how watchTags is being called .. you have a for loop but what are you wanting to do inside the for loop.. — MethodMan, Jul 02 '15 at 04:54
If your method is under time ticker event it will stop without finishing process. — Vijay Kumbhoje, Jul 02 '15 at 05:10

Doing timer.Enabled = false would stop Timer. Its same as timer.Stop();

timer.Enabled = false = System.Threading.Timer or System.Timers.Timer

timer.Stop(); =System.Windows.Forms.Timer

If you are using System.Timers.Timer you can stop like this

timer.Enabled = false

if you are using System.Threading.Timer, use this

timer.Change(Timeout.Infinite , Timeout.Infinite)

Or use

timer.Stop();

if you are using System.Windows.Forms.Timer

Okay. as Vijay Kumbhoje said in comments when the timer is finished , any process in watchTags method immediately ends without finishing job.

If someone in 2020 went here and see this accepted answer, it's not right. Elapsed event will not stop with timer.Stop(). This will only stop launching Elapsed event again, nothing else.

I think accepted answer in this thread doing it right: c# Task cancellation when using System.Timers
