Question

I am using a DispatchTimer to do something every second, how can I make it do Something for a set amount of time say 1 minute or 2 minutes? Do I need anther nested DispatcherTimer?

My code is below

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

    private void StartButton_Click(object sender, RoutedEventArgs e)
    {
        TimeSpan interval;
        interval = (TimeSpan)intervalPicker.Value;
        dt.Interval = interval;
        dt.Tick += new EventHandler(dt_Tick);
        dt.Start();
    }

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

I would appreciate if you could help me thanks.

Use the Stopwatch class:

Stopwatch sw = new Stopwatch();

private void StartButton_Click(object sender, RoutedEventArgs e)
{
    sw.Start();
    ...
}

void dt_Tick(object sender, EventArgs e)
{
   // stops the timer after 66 seconds
   if(sw.ElapsedMilliseconds/1000 > 66)
   {
       dt.Stop();
       sw.Reset();
   }          
}
