Executing methods at a specified time

Question

I would like to execute method at a specified time e.g. execute some method in five minutes. I don't need to execute it in interval ( every day or every hour), just once. I making web application with asp.net core 2.1. I would like to be able to add e.g. 3 jobs to do 1) in 5 min 2) in 10 min 3) in 15 min and expecting to perform when time is over. How can I do it in a simple way?

Why not use timers. Simple and easy...

private System.Timers.Timer myTimer;
private int minutes = Settings.Default.5MinuteTimer;

private void SetTimer()
{
    myTimer= new System.Timers.Timer(1000 * 60 * minutes);          
    myTimer.Elapsed += OnTimedEvent;
    myTimer.AutoReset = false; //Fire event only once.
    myTimer.Enabled = true;
}

private void OnTimedEvent(Object source, ElapsedEventArgs e)
{
    MyMethod();
}

private MyMethod()
{
    myTimer.Stop(); //Calling stop will also Dispose the timer.
    // Other code.
}
