With System.Timers.Timer you have more options, where System.Threading.Timer is a lightweight timer. I would recommend you to use System.Timers.Timer

Try this ...

using System.Timers;

Timer tmrExecutor = new Timer();

protected override void OnStart(string[] args)
{
      tmrExecutor.Elapsed += new ElapsedEventHandler(tmrExecutor_Elapsed); // adding Event
      tmrExecutor.Interval = 5000; // Set your time here 
      tmrExecutor.Enabled = true;
      tmrExecutor.Start();
}

private void tmrExecutor_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
      //Do your work here 
}

protected override void OnStop()
{
      tmrExecutor.Enabled = false;
}
