Answer 1

1. 指定名稱的BeginStoryboard

   <BeginStoryboard x:Name="Move"> 
   

2. 要暫停，添加此

   <EventTrigger RoutedEvent="MouseEnter"> 
       <PauseStoryboard BeginStoryboardName="Move"/> 
   </EventTrigger> 
   

3. 要恢復，添加此

   <EventTrigger RoutedEvent="MouseLeave"> 
       <ResumeStoryboard BeginStoryboardName="Move"/> 
   </EventTrigger>
