如何在WPF中暂停动画？

Question

假设有一个动画可以持续例如10秒，当鼠标进入相关控件时，如何暂停（不完全停止）动画，然后当鼠标离开时，动画继续完成剩下的动画？

Answer 1

使用PauseStoryboard和ResumeStoryboard类。例如：

<Control> 
    <Control.Triggers> 
     <EventTrigger RoutedEvent="Loaded"> 
      <BeginStoryboard x:Name="theStoryboard"> 
       ... 
      </BeginStoryboard> 
     </EventTrigger> 
     <EventTrigger RoutedEvent="MouseEnter"> 
      <PauseStoryboard BeginStoryboardName="theStoryboard"/> 
     </EventTrigger> 
     <EventTrigger RoutedEvent="MouseLeave"> 
      <ResumeStoryboard BeginStoryboardName="theStoryboard"/> 
     </EventTrigger> 
    </Control.Triggers> 
</Control>
