Question

I have a BackgroundWorker that creates a timer. The timer makes repeated calls to a DataTable. I only want the BackgroundWorker.RunWorkerCompleted event to get called when the timer stops. How do I do this?

Thanks.

Just create a loop in the BackgroundWorker‘s DoWork event handler and repeat the loop until the timer stops. More or less like so:

var worker = new BackgroundWorker();
worker.DoWork += (sender, e) =>
{
    var timer = new Timer();
    timer.Elapsed += (s, _e) =>
    {
       // call the database
    };

    timer.Start();

    while (timer.Enabled)
    {
        // at some point: timer.Stop();
    } 

    // if we are here, timer is no longer Enabled
    // RunWorkerCompleted event will be fired next
};

(Obviously I ommitted setting the timer’s Interval etc.)
