在WPF中的动画中重复之间暂停

我已将以下FadeIn/FadeOut动画应用于WPF的Canvas 。

 var fadingInOutAnimation = new DoubleAnimation { From = 1, To = 0, Duration = new Duration(TimeSpan.FromMilliseconds(1000)), AutoReverse = true, RepeatBehavior = RepeatBehavior.Forever, }; MyCanvas.BeginAnimation(OpacityProperty, fadingInOutAnimation); 

现在我希望它在到达动画结束时暂停1秒钟，然后再重复一次。

所以它是这样的：

 Animation --- Pause (1 Sec) --- Animation --- Pause (1 Sec) and so on.

您可以添加一个自动反转和重复的Storyboard，但其持续时间比动画更长：

 var fadeInOutAnimation = new DoubleAnimation() { From = 1, To = 0, Duration = TimeSpan.FromSeconds(1), }; var storyboard = new Storyboard { Duration = TimeSpan.FromSeconds(2), AutoReverse = true, RepeatBehavior = RepeatBehavior.Forever }; Storyboard.SetTarget(fadeInOutAnimation, MyCanvas); Storyboard.SetTargetProperty(fadeInOutAnimation, new PropertyPath(Canvas.OpacityProperty)); storyboard.Children.Add(fadeInOutAnimation); MyCanvas.BeginStoryboard(storyboard);
