Answer 1

System.Windows.Threading.DispatcherTimer dt = new System.Windows.Threading.DispatcherTimer();

dt.Interval = TimeSpan.FromMilliseconds(500);
dt.Tick +=new EventHandler(dt_Tick);

void dt_Tick(object sender, EventArgs e)
{
       //code
}

and

dt.start() ;

dt.stop() ;

Depending on what you're trying to do, you'll want to use:

• Timer , if you want to start a 'simple' background task : http://msdn.microsoft.com/en-us/library/system.threading.timer%28v=vs.95%29.aspx

• DispatcherTimer , if you want to modify the UI: http://msdn.microsoft.com/en-us/library/system.windows.threading.dispatchertimer%28v=vs.95%29.aspx
