如何在窗口加載事件（代碼後面）上觸發StoryBoard？

Question

我有故事板的窗口存儲在窗口的資源，如下所示：

<Storyboard x:Key="FadeInStoryBoard"> 
     <DoubleAnimation Storyboard.TargetName="GridNotificationWindow" From="0.01" To="1" Storyboard.TargetProperty="Opacity" Duration="0:0:2"/> 
     <DoubleAnimation Storyboard.TargetName="GridNotificationWindow" From="1" To="0" Storyboard.TargetProperty="Opacity" Duration="0:0:2" BeginTime="0:0:6"/> 
    </Storyboard> 

而且在後面的代碼如下：

private void Window_Loaded(object sender, RoutedEventArgs e) 
    { 
     Storyboard s = (Storyboard)this.TryFindResource("FadeInStoryBoard"); 
     if(s!=null) 
     { 
      BeginStoryboard(s); 
     } 
    }  

但似乎不工作... 如果我設置它在XAML，它的工作：

<EventTrigger RoutedEvent="Window.Loaded" SourceName="GridNotificationWindow"> 
       <BeginStoryboard x:Name="FadeInStoryBoard" > 
        <Storyboard> 
         <DoubleAnimation Storyboard.TargetName="GridNotificationWindow" From="0.01" To="1" Storyboard.TargetProperty="Opacity" Duration="0:0:2"/> 
         <DoubleAnimation Storyboard.TargetName="GridNotificationWindow" From="1" To="0" Storyboard.TargetProperty="Opacity" Duration="0:0:2" BeginTime="0:0:6"/> 
        </Storyboard> 
       </BeginStoryboard> 
      </EventTrigger> 

如何可以修復後面的代碼？

設定的目標調用BeginStoryboard前

Storyboard.SetTarget(s, TargetName);
