C# XAML：从代码隐藏设置情节提要动画的值

我有一个要求，我需要一个按钮在几秒钟内从屏幕的一端水平移动到另一端。我试过这个，在一定程度上奏效了

<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(CompositeTransform.TranslateX)" Storyboard.TargetName="button">
            <EasingDoubleKeyFrame KeyTime="0:0:1" Value="0" />
            <!--<EasingDoubleKeyFrame KeyTime="0:0:6.9" Value="{Binding MainPage.width}">-->
                <EasingDoubleKeyFrame KeyTime="0:0:6.9" Value="-1283.725">
                <EasingDoubleKeyFrame.EasingFunction>
                    <CircleEase EasingMode="EaseIn"/>
                </EasingDoubleKeyFrame.EasingFunction>
            </EasingDoubleKeyFrame>
        </DoubleAnimationUsingKeyFrames>
        <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(CompositeTransform.TranslateY)" Storyboard.TargetName="button">
            <EasingDoubleKeyFrame KeyTime="0:0:1" Value="0"/>
            <!--<EasingDoubleKeyFrame KeyTime="0:0:6.9" Value="{Binding Path=MainPage.height}">-->
            <EasingDoubleKeyFrame KeyTime="0:0:6.9" Value="-467.732">
                <EasingDoubleKeyFrame.EasingFunction>
                    <CircleEase EasingMode="EaseIn"/>
                </EasingDoubleKeyFrame.EasingFunction>
            </EasingDoubleKeyFrame>
        </DoubleAnimationUsingKeyFrames>

如果有简单的方法，请告诉我

我找不到绑定故事板表达式值的方法

但是，解决方法是每次手动设置。我们可以给它一个name属性，如：

    <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).    (CompositeTransform.TranslateX)" Storyboard.TargetName="button">
         <EasingDoubleKeyFrame KeyTime="0:0:1" Value="0" />
         <EasingDoubleKeyFrame x:Name="buttonTranslateX"  KeyTime="0:0:9.9" Value="0" />
     </DoubleAnimationUsingKeyFrames>

这将创建一个很好的小动画，其中一个对象将在大约9秒内在屏幕上水平移动

Rect bounds = Window.Current.Bounds;
static double height = 0;
static double  width = 0;

public MainPage()
{
    this.InitializeComponent();
    this.Loaded += MainPage_Loaded;
    height = bounds.Height;
    width = -1 * bounds.Width;
    buttonTranslateX.Value = width;
}
