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;
}

这可以很好地工作，但是我想将这个故事板移动到另一个程序集中。所以我需要指定StoryBoard.TargetName表单代码。我该怎么做呢？

Answer 1

附加的属性可以通过名为"Set" + PropertyName的静态帮助器方法从代码中设置

请参见C#示例here

Storyboard.SetTargetName(yourAnimation, "NotifyWindow"); 

Answer 2

为依赖项对象设置依赖项属性的标准方法与附加属性相同：

dependencyObjectInstance.SetValue(SampleClass.PropertyName + "Property", value);

在您的示例中：

fading.SetValue(Storyboard.TargetNameProperty, "NotifyWindow");
