How can I get my windows service to run at a specific interval?

I want to write a windows service. But it needs to run at specific times. For example, my service should email me every 5 minutes.

private Timer _timer;
private DateTime _lastRun = DateTime.Now;

protected override void OnStart(string[] args)
{
    _timer = new Timer(10 * 60 * 1000); // every 10 minutes
    _timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed);
    //...
}


private void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
    // ignore the time, just compare the date
    if (_lastRun.Date < DateTime.Now.Date)
    {
        // stop the timer while we are running the cleanup task
        _timer.Stop();
        //
        // do cleanup stuff
        //
        _lastRun = DateTime.Now;
        _timer.Start();
    }
}

I want my service to email me every 5 minutes.

For the above said functionality, you can use the combination of console application with windows scheduler.

Schedule your exe to execute every 5 mins. Your exe will email you and stop. Is there anything specific you want to achieve through windows service?

If you need to do an operation on a timer, then you have two choices

  1. Create a Windows Service and implement some kind of scheduling. This can be complex, so be prepared to that you may spend a lot of time solving issues that have already been solved.
  2. You could setup a scheduled task instead that calls your application.

It all depends how much control you really need.

Take a look at Quartz.NET or search for "Windows Task Scheduling".

The first approach is programmatic and the later is configuration.

Your code looks good, but did you make a call to timer.start() in the first place during OnStart?

You might want to use something like Quartz.net in your service. You can then use cron expressions to schedule "jobs" within your service.

Why not just add a timer to your service who does what you want on the interval you configure?
