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

I know this answer is late but if you want your System.Timers.Timer to be fired within 100ms (default interval) then you could simply just initialize the Timer object without a specified interval, then set the interval within the called function to whatever you like. Here is an example of what I use in my Windows Service:

private static Timer _timer;

protected override void OnStart(string[] args)
{
    _timer = new Timer(); //This will set the default interval
    _timer.AutoReset = false;
    _timer.Elapsed = OnTimer;
    _timer.Start();
}

private void OnTimer(object sender, ElapsedEventArgs args)
{
    //Do some work here
    _timer.Stop();
    _timer.Interval = 50000; //Set your new interval here
    _timer.Start();
}
