WP7 Silverlight 上基于帧的动画
来自 iOS 世界，我们有 UIImageView 和属性animationImages： http://developer.apple.com/library/ios/documentation/UIKit/Reference/UIImageView_Class/Reference/Reference.html#//apple_ref/occ/instp/UIImageView/animationImages
其中AnimationImages 只是任意动画帧的数组。您指定图像（可能是 15 个），然后在其他属性之一中设置总动画时间（可能是 4 秒），然后启动动画，animationImages 中的图像将以均匀的帧速率在指定时间内按顺序播放。
我如何对 WP7/Silverlight 执行同样的操作？这一切表达混合看起来很棒，但我只是找不到一种方法来动画图像源（我猜这可能是不可能的）。我会怎样做同样的事情？我是否应该为动画中的每个帧添加一个唯一的图像对象，然后使用可见性/不透明度属性并手动创建所有间隔开的关键帧？这听起来像是很多额外的工作+开销，这不是一个好方法......
Coming from the iOS world where we have UIImageView and the property animationImages:
http://developer.apple.com/library/ios/documentation/UIKit/Reference/UIImageView_Class/Reference/Reference.html#//apple_ref/occ/instp/UIImageView/animationImages
Where animationImages is just an array of arbitrary animation frames. You specify the images (maybe 15), then set the total animation time (maybe 4 seconds) in one of the other properties, then just start the anim and the images in animationImages will play sequentially over the specified time with an even frame rate.
How would I do the same with WP7/Silverlight? This all Expression Blend seems wonderful, but I just can't find a way to animate the image source (I'm guessing it might be impossible). How would I do the same? Should I add a unique image object for each frame in the animation, then play around with visibility/opacity properties and manually have to create all the spaced out key frames? That sounds like a lot of extra work + overhead and not a nice way to go...

尝试这些链接。尤其是第一个，我想第一个就解决了你所有的疑惑。在 wp7 中，我们可以选择两种选项：基于 XAML 的（静态）动画/或借助 C# 代码。通过使用混合，你可以毫无问题地创建所有静态动画。这里的动画是在页面框架的基础上工作的。如果您有兴趣了解更多有关动画的信息，也可以尝试一下；

Try out these links. Especially the first one, I think the first one resolve all you doubts. In wp7 we can go for two options either XAML based (static) animations / or with the help of C# code. By using blend u can create all sot of static animation with out any issue. Here the animation is working on the basis of page frames. If u are interested in learning more about Animation try this too;

您实际上可以对 Image.Source 属性进行动画处理，这是一个教程。
