WPF 中的动画主要分为 AnimationTimeline（简单动画） 和 Storyboard（一组协同的动画）。

一、简单线性动画

        private void ButtonBase_OnClick(object sender, RoutedEventArgs e)
        {
            DoubleAnimation dx = new DoubleAnimation();
            DoubleAnimation dy = new DoubleAnimation();

            // 指定起点
            dx.From = 0;
            dy.From = 0;

            // 指定终点
            dx.To = new Random().NextDouble() * 200;
            dy.To = new Random().NextDouble() * 200;

            //// 指定幅度
            //dx.By = 100;
            //dy.By = 100;

            // 指定时长
            dx.Duration = new Duration(TimeSpan.FromMilliseconds(1000));
            dy.Duration = new Duration(TimeSpan.FromMilliseconds(2000));

            // 动画主体（TranslateTransform）
            tt.BeginAnimation(TranslateTransform.XProperty,dx);
            tt.BeginAnimation(TranslateTransform.YProperty,dy);
        }

二、高级动画控制

        private void ButtonBase_OnClick1(object sender, RoutedEventArgs e)
        {
           DoubleAnimation dx=new DoubleAnimation();
           DoubleAnimation dy=new DoubleAnimation();

            // 设置弹跳
            BounceEase be=new BounceEase()
            {
                Bounces = 4, // 弹跳次数
                Bounciness = 2,// 弹跳值
            };
            dy.EasingFunction = be;

            // 设置终点
            dx.To = 300;
            dy.To = 300;

            // 设置时长
            dx.Duration = new Duration(TimeSpan.FromMilliseconds(2000));
           dy.Duration = new Duration(TimeSpan.FromMilliseconds(2000));

            // 动画主体
            tt1.BeginAnimation(TranslateTransform.XProperty,dx);
           tt1.BeginAnimation(TranslateTransform.YProperty, dy);
        }

三、关键帧动画

        private void ButtonBase_OnClick2(object sender, RoutedEventArgs e)
        {
            PathGeometry path=this.FindResource("MovePath") as PathGeometry;
            Duration duration =new Duration(TimeSpan.FromMilliseconds(3000));

            // 创建动画
            DoubleAnimationUsingPath dx=new DoubleAnimationUsingPath()
            {
                PathGeometry = path,
                Source = PathAnimationSource.X,
                Duration = duration,
            };

            DoubleAnimationUsingPath dy = new DoubleAnimationUsingPath()
            {
                PathGeometry = path,
                Source = PathAnimationSource.Y,
                Duration = duration,
            };

            // 执行动画
            tt2.BeginAnimation(TranslateTransform.XProperty,dx);
            tt2.BeginAnimation(TranslateTransform.YProperty, dy);
        }

四、场景——Storyboard

例如：实现三个小球（红球、绿球、蓝球）分别沿着跑到运动的动画，具体示例如下：
