我如何在 WPF 中的段之间停止动画一段时间

Question

我有一个移动点。它有 2 个片段，我需要暂时停止它们之间的动画。 我如何到达它？ 有什么办法可以达到这个目的吗？

private void TrainAnim()
        {
            
            Path myPath = new Path();
            myPath.Stroke = Brushes.Black;
            myPath.StrokeThickness = 1;

            
            PathGeometry pathGeometry = new PathGeometry();
            PathFigure pathFigure = new PathFigure();
            pathFigure.StartPoint = new Point(10, 20);
            pathFigure.Segments.Add(new LineSegment(new Point(100, 20), true));
            
            pathFigure.Segments.Add(new LineSegment(new Point(400, 20), true));

            pathGeometry.Figures.Add(pathFigure);

            
            myPath.Data = pathGeometry;

            Ellipse ellipse = new Ellipse
            {
                Fill = Brushes.Purple,
                Height = 20,
                Width = 20,
                Margin = new Thickness(0, 0, 0, 0)
            };

            DoubleAnimationUsingPath anim = new DoubleAnimationUsingPath
            {
                PathGeometry = pathGeometry,
                Duration = TimeSpan.FromSeconds(1),
            };

            Storyboard storyboard = new Storyboard
            {
                
            };

            Storyboard.SetTargetName(anim, ellipse.Name);
            Storyboard.SetTargetProperty(anim, new PropertyPath(Canvas.LeftProperty));
            storyboard.Children.Add(anim);

            canvasAnim.Children.Add(ellipse);
            canvasAnim.Children.Add(myPath);

            ellipse.BeginAnimation(Canvas.LeftProperty, anim);
        }

有什么办法吗？ canvasAnim 是 MainWindow 上的 Canvas
