    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            //border中可以容纳一个其他元素
            Border br = new Border();//实例化创建一个border
            br.Width = br.Height = 100;//设置border的宽高
            br.Background = Brushes.Pink;//设置border的背景颜色
            //设置border的left和top
            Canvas.SetLeft(br, 100);
            Canvas.SetTop(br, 100);
            BG.Children.Add(br);//将border加入BG画布中
            //边框的厚度
            br.BorderThickness = new Thickness(20);
            //边框的颜色
            br.BorderBrush = Brushes.Red;
            //边框圆角
            br.CornerRadius = new CornerRadius(50);

            //动画
            //1.找剧本,故事本
            Storyboard story1 = new Storyboard();
            //2.选择动画的类型
            //两点动画:差值动画
            DoubleAnimation da = new DoubleAnimation();
            //3.设置动画的起始值
            da.From = 100;
            //设置动画的终止值
            da.To = 500;
            //设置动画的进行时间
            da.Duration = new Duration(TimeSpan.FromSeconds(2));
            //4.设置某个动画的男女一号
            Storyboard.SetTarget(da, br);
            //5.设置动画的属性
            Storyboard.SetTargetProperty(da, new PropertyPath("(Canvas.Top)"));
            da.AutoReverse = true;//动画的可选属性1,是否反着播放
           // da.RepeatBehavior = RepeatBehavior.Forever;//动画的可选属性2,是否重复播放
            da.RepeatBehavior = new RepeatBehavior(TimeSpan.FromSeconds(50));//可以设置重复的次数/时间
            //将动画添加进故事版里面
            story1.Children.Add(da);
            story1.Begin();
        }
    }
}
