UWP - 为什么我的简单动画不是 运行

Question

我现在完全迷路了。我的动画有什么问题？为什么不是运行？任何帮助将不胜感激！我想开发一种圆形进度条，它是 "rolling in" 就好像进度条被填满了一样。

以下代码在 MainPage 的已加载处理程序中的空 UWP 应用程序中运行。没有别的...

ArcSegment myArcSegment = new ArcSegment();
myArcSegment.Size = new Size(90, 80);
myArcSegment.SweepDirection = SweepDirection.Clockwise;

PathSegmentCollection myPathSegmentCollection = new PathSegmentCollection();
myPathSegmentCollection.Add(myArcSegment);

PathFigure myPathFigure = new PathFigure();

myPathFigure.StartPoint = new Point(100, 200);

myPathFigure.Segments = myPathSegmentCollection;

PathFigureCollection myPathFigureCollection = new PathFigureCollection();
myPathFigureCollection.Add(myPathFigure);

PathGeometry myPathGeometry = new PathGeometry();
myPathGeometry.Figures = myPathFigureCollection;

Path myPath = new Path();
myPath.Stroke = new SolidColorBrush(Colors.Aqua);
myPath.StrokeThickness = 1;

myPath.Data = myPathGeometry;

PointAnimation mySizeAnimation = new PointAnimation();
mySizeAnimation.Duration = TimeSpan.FromSeconds(2);

mySizeAnimation.From = new Point(90, 80);
mySizeAnimation.To = new Point(500, 200);

Storyboard.SetTarget(mySizeAnimation, myArcSegment);
Storyboard.SetTargetProperty(mySizeAnimation, nameof(ArcSegment.Point));

Storyboard ellipseStoryboard = new Storyboard();
ellipseStoryboard.Children.Add(mySizeAnimation);

myPath.Loaded += delegate (object o, RoutedEventArgs e)
{
    ellipseStoryboard.Begin();
};

Canvas containerCanvas = new Canvas();
containerCanvas.Children.Add(myPath);

Content = containerCanvas;

感谢您的帮助！

天哪...我刚刚读了这个post：http://blog.jerrynixon.com/2012/06/windows-8-animated-pie-slice.html

无意中我读到了关于 EnableDependendAnimation 属性... 从未听说过，但将其设置为 true刚刚制作了动画 运行。我现在会仔细阅读。无论如何谢谢！
