Question

Is there an analog to the following static function from the Qt library in Windows Forms?

http://doc.qt.io/qt-5/qtimer.html#singleShot

The best I can come up with is the following:

ThreadPool.QueueUserWorkItem((o) =>
{
    Thread.Sleep(someNumberOfMilliseconds);
    DoDelayedWorkHere();
});

UPDATE

This does the trick using System.Windows.Forms.Timer.

var timer = new System.Windows.Forms.Timer();
timer.Interval = someNumberOfMilliseconds;
timer.Tick += (o, args) =>
    {
        timer.Stop();
        DoDelayedWorkHere();
    };
timer.Start();

QTimer is a synchronous timer, just like the Winforms Timer. Threading or one of the other Timer classes is not a substitute. A single-shot is easy to implement, just set the timer’s Enabled property to false in the Tick event handler. No danger of a race:

    private void timer1_Tick(object sender, EventArgs e) {
        ((Timer)sender).Enabled = false;
        // etc..
    }
