storyboard创建动画有关问题

storyboard创建动画问题
要求：
创建一个button(起始坐标为(0,0))，沿x轴方向由0移动到100
在xaml中可以正常实现（使用），实现方法如下:

C# code

<Window.Resources>        <Storyboard x:Key="sboard">            <DoubleAnimation Storyboard.TargetName="ttXaml" Storyboard.TargetProperty="X"                             Duration="00:00:01" From="0" To="30" />        </Storyboard>    </Window.Resources>    <Grid>        <Button x:Name="button1" Content="click" Click="button1_Click" Width="50" Height="50">               <Rectangle.RenderTransform>                <TranslateTransform x:Name="ttXaml"/>            </Rectangle.RenderTransform>        </Button>    </Grid>

C#部分代码如下：

C# code

(this.Resources["sboard"] as Storyboard).Begin();

代码运行正常，现在我想根据xaml代码转换成C#代码，我做了如下转换:

C# code

            TranslateTransform tt = new TranslateTransform();            // RotateTransform rt = new RotateTransform();            this.button1.RenderTransform = tt;            this.button1.Name = "button1";            NameScope.SetNameScope(this, new NameScope());            this.RegisterName(this.button1.Name, this.button1);            DoubleAnimation xAnimation = new DoubleAnimation();            xAnimation.From = 0;            xAnimation.To = 100;            xAnimation.Duration = new Duration(TimeSpan.FromSeconds(1));            DependencyProperty[] propertyChain = new DependencyProperty[] // 使用属性链的时候应用            {                Button.RenderTransformProperty,                TranslateTransform.XProperty,                RotateTransform.AngleProperty // 调整角度时候用            };            Storyboard story = new Storyboard();            // story.AutoReverse = true;            // story.RepeatBehavior = RepeatBehavior.Forever;            story.Children.Add(xAnimation);            //Storyboard.SetTargetName(xAnimation, this.button1.Name);            //Storyboard.SetTargetProperty(xAnimation, new PropertyPath("(0).(1)", propertyChain));            Storyboard.SetTarget(xAnimation, tt);            Storyboard.SetTargetProperty(xAnimation, new PropertyPath(TranslateTransform.XProperty));            //Storyboard.SetTarget(xAnimation, rt);            //Storyboard.SetTargetProperty(xAnimation, new PropertyPath(RotateTransform.AngleProperty));            story.Begin(this);

运行之后却没有反应，但是，如果使用：
  //Storyboard.SetTargetName(xAnimation, this.button1.Name);
  //Storyboard.SetTargetProperty(xAnimation, new PropertyPath("(0).(1)", propertyChain));
这个方法就可以得到想要的效果。
我看xaml代码部分的TargeName属性设置为了"ttXaml"也就是对应对象是TranslateTransform变形啊，为什么我在C#代买中这样写就没有效果呢？能帮忙看下是否代码写错了？
非常感谢！

“RenderTrasform.X"

A Storyboard can be used to animate dependency properties of animatable classes (for more information about what makes a class animatable, see the Animation Overview). However, because storyboarding is a framework-level feature, the object must belong to the NameScope of a FrameworkElement or a FrameworkContentElement.
