在win8应用程序中,我正在尝试使用小动画来制作Rectangle 0的高度

像Opacity这样的属性工作正常,但我无法在高度或宽度上添加动画.

<Page.Resources>
    <Storyboard x:Name="NewStory">
        <DoubleAnimation Storyboard.TargetName="MyRectangle"  Storyboard.TargetProperty="Height" From="100" To="0" Duration="0:0:1" />
    </Storyboard>
</Page.Resources> 

<Rectangle Name="MyRectangle" Width="100" Height="100" Tapped="MyRectangle_OnTapped">

private void MyRectangle_OnTapped(object sender, TappedRoutedEventArgs e)
{
    NewStory.Begin();
}
