在WPF動畫中重複之間暫停

Question

我已將以下FadeIn/FadeOut動畫應用於WPF中的Canvas。

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

MyCanvas.BeginAnimation(OpacityProperty, fadingInOutAnimation); 

現在我想讓它暫停1秒，當它達到動畫結束之前再次重複。

因此，它是這樣的：

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

您可以添加一個故事板，做自動倒車和重複，但具有比動畫持續時間較長：

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);
