Alternative to Thread.Sleep that block

问题

I am looking for an alternative to calling Thread.Sleep which does not block the thread but instead returns the thread back into the thread pool. Does such a thing exist?

回答1:

Use Task.Delay

await Task.Delay(delay);

回答2:

If the thread is returning to the pool, then it isn't going to do any more work in the method in question. Make the next bit of the method a separate method, and create a Timer that calls it.

回答3:

You can use also a Timer for example:

using System.Timers;

private void Main()
{
    Timer t = new Timer();
    t.Interval = 5000; // 5 seconds
    t.AutoReset = false;
    t.Elapsed += new SleepDone(TimerElapsed);
    t.Start();
}

private void SleepDone(object sender, ElapsedEventArgs e)
{
    Console.WriteLine("HERE WHAT COME AFTER SLEEP");
}
