如何在C#中设置Storyboard.TargetProperty？

我正在用C#开发wpf应用程序。下面的xaml代码对我来说运行良好

<VisualStateManager.VisualStateGroups>
    <VisualStateGroup x:Name="VisualStateGroup">
        <VisualState x:Name="DefaultVisualState">
            <Storyboard/>
        </VisualState>
        <VisualState x:Name="FocusVisualState">
            <Storyboard>
                <ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(Shape.Fill).(SolidColorBrush.Color)" Storyboard.TargetName="CircleEllipse1">
                    <EasingColorKeyFrame KeyTime="0" Value="#FF0004FF"/>
                </ColorAnimationUsingKeyFrames>
                <ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(TextElement.Background).(SolidColorBrush.Color)" Storyboard.TargetName="TextBlock1">
                    <EasingColorKeyFrame KeyTime="0" Value="#FFBCB0B0"/>
                </ColorAnimationUsingKeyFrames>
            </Storyboard>
        </VisualState>
    </VisualStateGroup>
</VisualStateManager.VisualStateGroups>

在上面的代码中，我应该如何设置

故事板.TargetProperty=“（Shape.Fill）。（SolidColorBrush.Color）”

和

故事板.TargetProperty=“（TextElement.Background）。（SolidColorBrush.Color）”

在C#

中，您需要将其指定为字符串

private void AnimateColor(string ellipseName, Color ellipseColor, string textBlockName, Color textBlockColor)
            {
                EasingColorKeyFrame easingColorKeyFrameEllipseObj = new EasingColorKeyFrame();
                easingColorKeyFrameEllipseObj.KeyTime = KeyTime.FromTimeSpan(TimeSpan.FromSeconds(12));
                easingColorKeyFrameEllipseObj.Value = ellipseColor;

                ColorAnimationUsingKeyFrames colorAnimationUsingKeyFramesEllipseObj = new ColorAnimationUsingKeyFrames();
                Storyboard.SetTargetName(colorAnimationUsingKeyFramesEllipseObj, ellipseName);
                Storyboard.SetTargetProperty(
                    colorAnimationUsingKeyFramesEllipseObj, new PropertyPath("(Shape.Fill).(SolidColorBrush.Color)"));
                colorAnimationUsingKeyFramesEllipseObj.KeyFrames.Add(easingColorKeyFrameEllipseObj);

                EasingColorKeyFrame easingColorKeyFrameTextBlockObj = new EasingColorKeyFrame();
                easingColorKeyFrameTextBlockObj.KeyTime = KeyTime.FromTimeSpan(TimeSpan.FromSeconds(12));
                easingColorKeyFrameTextBlockObj.Value = textBlockColor;

                ColorAnimationUsingKeyFrames colorAnimationUsingKeyFramesTextBlockObj = new ColorAnimationUsingKeyFrames();
                Storyboard.SetTargetName(colorAnimationUsingKeyFramesTextBlockObj, textBlockName);
                Storyboard.SetTargetProperty(
                    colorAnimationUsingKeyFramesTextBlockObj, new PropertyPath("(TextElement.Background).(SolidColorBrush.Color)"));
                colorAnimationUsingKeyFramesTextBlockObj.KeyFrames.Add(easingColorKeyFrameTextBlockObj);


                Storyboard storyboard = new Storyboard();

                storyboard.Children.Add(colorAnimationUsingKeyFramesEllipseObj);
                storyboard.Children.Add(colorAnimationUsingKeyFramesTextBlockObj);

                storyboard.Begin(this, true);
            }

private void AnimateColor(string ellipseName, Color ellipseColor, string textBlockName, Color textBlockColor)
            {
                EasingColorKeyFrame easingColorKeyFrameEllipseObj = new EasingColorKeyFrame();
                easingColorKeyFrameEllipseObj.KeyTime = KeyTime.FromTimeSpan(TimeSpan.FromSeconds(12));
                easingColorKeyFrameEllipseObj.Value = ellipseColor;

                ColorAnimationUsingKeyFrames colorAnimationUsingKeyFramesEllipseObj = new ColorAnimationUsingKeyFrames();
                Storyboard.SetTargetName(colorAnimationUsingKeyFramesEllipseObj, ellipseName);
                Storyboard.SetTargetProperty(
                    colorAnimationUsingKeyFramesEllipseObj, new PropertyPath("(Shape.Fill).(SolidColorBrush.Color)"));
                colorAnimationUsingKeyFramesEllipseObj.KeyFrames.Add(easingColorKeyFrameEllipseObj);

                EasingColorKeyFrame easingColorKeyFrameTextBlockObj = new EasingColorKeyFrame();
                easingColorKeyFrameTextBlockObj.KeyTime = KeyTime.FromTimeSpan(TimeSpan.FromSeconds(12));
                easingColorKeyFrameTextBlockObj.Value = textBlockColor;

                ColorAnimationUsingKeyFrames colorAnimationUsingKeyFramesTextBlockObj = new ColorAnimationUsingKeyFrames();
                Storyboard.SetTargetName(colorAnimationUsingKeyFramesTextBlockObj, textBlockName);
                Storyboard.SetTargetProperty(
                    colorAnimationUsingKeyFramesTextBlockObj, new PropertyPath("(TextElement.Background).(SolidColorBrush.Color)"));
                colorAnimationUsingKeyFramesTextBlockObj.KeyFrames.Add(easingColorKeyFrameTextBlockObj);


                Storyboard storyboard = new Storyboard();

                storyboard.Children.Add(colorAnimationUsingKeyFramesEllipseObj);
                storyboard.Children.Add(colorAnimationUsingKeyFramesTextBlockObj);

                storyboard.Begin(this, true);
            }
