How to fire timer.Elapsed event immediately

Question

I\'m using the System.Timers.Timer class to create a timer with an Timer.Elapsed event. The thing is the Timer.Elapsed event is fired

Answer 1

Task.Run(() =>
{
   Timer_Elapsed(null, null);
});

After Timer creation/configuration, worked fine for me...

Answer 2

I just called the **ElapsedEventHandler** with null parameters.

Answer 3

not sure about System.Timers.Timer but try

System.Threading.Timer T = new System.Threading.Timer(new TimerCallback(DoSomething), null, 0, 30000);

This starts immediately (0 milliseconds for first run, 30000 milliseconds for subsequents runs)...

Answer 4

Here is the easy answer. (Assuming you're using a Windows form)

After dragging your timer control to your form, set the enabled property to true, and the Interval property to whatever you want the initial value to be. (100 is the default and will start the tick event immediately)

Then within your tick event, simply check the value of the Interval property. If it is not your desired value, set it. It's that simple. The same can be accomplished in your C# code if creating a timer on the fly.
