c# - StoryBoard - 从代码隐藏设置目标名称

Question

我在资源中有 Storyboard

  <Window.Resources>
    <Storyboard x:Key="Fading" Storyboard.TargetName="NotifyWindow" Storyboard.TargetProperty="Opacity" >
        <DoubleAnimation From="1" To="0" Duration="0:0:1">
        </DoubleAnimation>
    </Storyboard>
  </Window.Resources>

在 WindowClosing 上我有下一个代码

private void NotifyWindow_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{
    Storyboard fading = this.Resources["Fading"] as Storyboard;
    if (fading != null && !fadingCompleted)
    {
        fading.Completed += FadingStoryBoard_Completed;
        fading.Begin();
        e.Cancel = true;
    }
}

private void FadingStoryBoard_Completed(object sender, EventArgs e)
{
   fadingCompleted = true;
   Close();
   fadingCompleted = false;
}

这工作正常，但我想将这个 Storyboard移动到另一个程序集。所以我需要指定 StoryBoard.TargetName 表单代码。我该怎么做？

附加属性可以通过静态辅助方法从代码中设置:"Set"+ PropertyName

参见 C# 示例 here :

Storyboard.SetTargetName(yourAnimation, "NotifyWindow");
