Question

I tried following code to run timer in class library but timer_Elapsed wasn’t fired. I also tried using timer from System.Windows.Forms but it didn’t worked.

private static void SetTimer(DateTime dateTime)
{
    timer = new System.Timers.Timer();
    TimeSpan timeSpan = dateTime - DateTime.Now;
    timer.Interval = timeSpan.Milliseconds;
    timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed);
    timer.Enabled = true;
    timer.Start();
}

private static void timer_Elapsed(object myobject, System.Timers.ElapsedEventArgs e) 
{ 
    timer.Enabled = false; 
    timer.Stop(); 
    Start(_appCastURL, _remindLaterAt, _remindLaterFormat); 
}

Answer 1

Removed Static from the timer declaration and remove static from event and SetTimer method, put it in the class extending Form in the class library and it worked.

private void SetTimer(DateTime remindLater)
{
    timer = new System.Timers.Timer();
    TimeSpan timeSpan = remindLater - DateTime.Now;
    timer.Interval = (int) timeSpan.TotalMilliseconds;
    timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed);
    timer.Start();
}

private void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
    timer.Stop();
    AutoUpdater.Start(appCast, remindLaterAt, remindLaterFormat);
}
