System.Timers.Timer: How to raise elapsed event after start interval?

I have simple timer:

private System.Timers.Timer _timer;
public Ctor()
{
      _timer = new System.Timers.Timer(timeout);
      _timer.Elapsed += Timer_Elapsed;
      _timer.Start();
}

How to make that timer rise Elapsed event after timeout time expired? It is for the first elapsed event, of course.

I think you're asking for a timer to be started after an initial delay? If that's the case then consider using a System.Threading.Timers.Timer instead, as follows:

int initialDelay = 5000; // five seconds
int timerPeriod = 1000; // one second
var timer = new Timer(_ => MethodToCallWhenExpired(), null, initialDelay, timerPeriod);

Alternatively you can use Timeout.Infinite and then call the Change() method to alter the Timer behaviour after creation.

Sorry if that's not what you were asking though! :)

A Timer does exactly what you want , it raises the event after the specified interval elapses. If you don't want it to be recurring (Runs once only), then set the AutoResetProperty:

public Ctor()
{
      _timer = new System.Timers.Timer(timeout);
      _timer.AutoReset = false;
      _timer.Elapsed += Timer_Elapsed;
      _timer.Start();
}


private void Timer_Elapsed(object sender, ElapsedEventArgs e)
{
    // your code here runs after the timeout elapsed
}
