Question

Could someone please provide me with an example on how to use the System.Windows.Forms.Timer in a windows service. The timer should ‘invoke’ a non-static windows service method every 10 seconds. I have (unsuccessfully) tried this in my OnStart method:

_timer.Tick += new EventHandler(StartProcessingItems);
_timer.Interval = 10000;
_timer.Enabled = true;
_timer.Start();    

Here StartProcessingItems is my on-static windows service method.

Answer 1

use instead System.Threading.Timer:

var t = new Timer(o => 
{
   Console.WriteLine("Hello from the past! " + (DateTime)o);
}, DateTime.Now, TimeSpan.FromSeconds(10), TimeSpan.FromMinutes(1));

It will execute the delegate 10s after, and then with a frequency of 1min
