c# - 如何在 C# 中为 Windows Phone 7 延迟一个方法？

Question

我有一个方法。

public bool bBIntersectsBT(Rect barTopTipRect, Rect barBottomTipRect, Rect blueBallRect)
    {
        barTopTipRect.Intersect(blueBallRect);
        barBottomTipRect.Intersect(blueBallRect);

        if (barTopTipRect.IsEmpty && barBottomTipRect.IsEmpty)
        {
            return false;
        }
        else
        {
            return true;
        }
    }

我想在再次执行此方法之前将此方法延迟 2 秒。我已经阅读了有关 Thread.Sleep 的内容，但是，这不是我想要的。我不希望程序暂停和恢复。

使用 DispatcherTimer:

DispatcherTimer timer = new DispatcherTimer();

//TimeSpan is in format: Days, hours, minutes, seconds, milliseconds.
timer.Interval = new TimeSpan(0, 0, 0, 2);
timer.Tick += timerTick;
timer.Start();

private void timerTick(Object sender, EventArgs e)
{
    //Your code you want to execute every 2 seconds

    //If you want to stop after the two seconds just add timer.Stop() here
}
