WPF中PropertyPath疑问
我想在点击一个按钮的时候对一个image进行一个动画效果，就是把他略微放大再还原，代码如下：
前台：

XML code

<WrapPanel>            <Image Name="img1" Margin="10" Height="130" Width="130"  Source="/WpfApplication1;component/Images/aa.jpg" Stretch="Uniform"/>            <Image Name="img2" Margin="10" Height="130" Width="130"  Source="/WpfApplication1;component/Images/aa.jpg" Stretch="Uniform"/>            <Image Name="img3" Margin="10" Height="130" Width="130"  Source="/WpfApplication1;component/Images/aa.jpg" Stretch="Uniform"/>            <Image Name="img4" Margin="10" Height="130" Width="130"  Source="/WpfApplication1;component/Images/aa.jpg" Stretch="Uniform"/>            <Image Name="img5" Margin="10" Height="130" Width="130"  Source="/WpfApplication1;component/Images/aa.jpg" Stretch="Uniform"/>            <Image Name="img6" Margin="10" Height="130" Width="130"  Source="/WpfApplication1;component/Images/aa.jpg" Stretch="Uniform"/>            <Image Name="img7" Margin="10" Height="130" Width="130"  Source="/WpfApplication1;component/Images/aa.jpg" Stretch="Uniform"/>        </WrapPanel>

后台：

C# code

 private void button1_Click(object sender, RoutedEventArgs e)        {            Storyboard storyboard = new Storyboard();            DoubleAnimationUsingKeyFrames daufs_w = new DoubleAnimationUsingKeyFrames();            daufs_w.KeyFrames.Add(new LinearDoubleKeyFrame(140, KeyTime.FromTimeSpan(TimeSpan.FromMilliseconds(500))));            daufs_w.KeyFrames.Add(new LinearDoubleKeyFrame(130, KeyTime.FromTimeSpan(TimeSpan.FromMilliseconds(1000))));            DoubleAnimationUsingKeyFrames daufs_h = new DoubleAnimationUsingKeyFrames();            daufs_h.KeyFrames.Add(new LinearDoubleKeyFrame(140, KeyTime.FromTimeSpan(TimeSpan.FromMilliseconds(500))));            daufs_h.KeyFrames.Add(new LinearDoubleKeyFrame(130, KeyTime.FromTimeSpan(TimeSpan.FromMilliseconds(1000))));            DoubleAnimationUsingKeyFrames daufs_margin = new DoubleAnimationUsingKeyFrames();            daufs_margin.KeyFrames.Add(new LinearDoubleKeyFrame(5, KeyTime.FromTimeSpan(TimeSpan.FromMilliseconds(500))));            daufs_margin.KeyFrames.Add(new LinearDoubleKeyFrame(10, KeyTime.FromTimeSpan(TimeSpan.FromMilliseconds(1000))));            Storyboard.SetTarget(daufs_w, img2);            Storyboard.SetTarget(daufs_h, img2);            Storyboard.SetTargetProperty(daufs_w, new PropertyPath("Width"));            Storyboard.SetTargetProperty(daufs_h, new PropertyPath("Height"));            storyboard.Children.Add(daufs_w);            storyboard.Children.Add(daufs_h);            Storyboard.SetTarget(daufs_margin, img2);            //下面的代码有问题            //Storyboard.SetTargetProperty(daufs_margin, new PropertyPath("Margin.Left"));            //Storyboard.SetTargetProperty(daufs_margin, new PropertyPath("Margin/Right"));            //Storyboard.SetTargetProperty(daufs_margin, new PropertyPath("Margin/Top"));            //Storyboard.SetTargetProperty(daufs_margin, new PropertyPath("Margin/Bottom"));            //storyboard.Children.Add(daufs_margin);            if (!Resources.Contains("da"))            {                Resources.Add("da", storyboard);            }            storyboard.Begin();        }

从代码可以看到，因为有一堆图片放在WrapPanel下，我要的效果只是放大其中一个图片，且不能影响其他元素的布局，所以我的做法是同时改变image的Height，Width还有Margin，但是Margin这个东西是Thickness类型的，我的目的是要改变Margin里面的Left，Right，Bottom，Top，请问这些属性如何绑定到PropertyPath，使动画可以成功跑起？？请各位高人赐教,在下不胜感激！！！

[解决办法]
自问自答？？？
我也有个弱弱的问题
就是 new PropertyPath("Margin") 是啥意思？？？
把Margin对象作为字符串属性？？？
不懂？？
