How to cancel await Task.Delay()?

by

Use the overload of Task.Delay which accepts a CancellationToken

public async Task TaskDelayTest(CancellationToken token)
{
    while (LoopCheck)
    {
        token.throwIfCancellationRequested();
        for (int i = 0; i < 100; i++)
        {
            textBox1.Text = i.ToString();
            await Task.Delay(1000, token);
        }
    }
}

var tokenSource = new CancellationTokenSource();
TaskDelayTest(tokenSource.Token);
...
tokenSource.Cancel();
