WPF从后面的C＃代码访问资源

Question

This is my XAML:

   <TabControl Name="me" SelectionChanged="me_SelectionChanged">

        <TabControl.Resources>

            <Storyboard x:Name="fadein" x:Key="fatal">

                <DoubleAnimation x:Name="fade" Storyboard.TargetProperty="Opacity" To="1" Duration="0:0:3">

                </DoubleAnimation>
            </Storyboard>
        </TabControl.Resources>
        <TabItem Header="MyTabItem">
            <Grid Background="Black" HorizontalAlignment="Stretch" Opacity="0.7"></Grid>


        </TabItem>

    </TabControl>

I'm trying to access the fatal animation through the C# code but I can't...

    public void me_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {

        if (sender == null)
            return;

        fatal.Stop();// cant recognize `fatal`
    }

C# can't identify what fatal is.

What have I done wrong?

Answer 1

Well you can do the following:

StoryBoard sb = (StoryBoard)me.FindResource("fatal");

or

StoryBoard sb = (StoryBoard)me.Resources["fatal"];
