探索 Silverlight：声音、视频与深度缩放功能全解析

1. 综合示例代码

以下是一段结合视频、交互性和特效的代码示例：

squareMoveStoryboard.Stop(); 
Canvas.SetLeft(rectangle, left); 
Canvas.SetTop(rectangle, top); 

// Attach the animation. 
squareMoveStoryboard.Stop(); 
Storyboard.SetTarget(squareMoveStoryboard, rectangle); 

// Choose a random direction and movement amount. 
Random rand = new Random(); 
int sign = 1; 
if (rand.Next(0, 2) == 0) sign = -1; 
leftAnimation.To = Canvas.GetLeft(rectangle) + rand.Next(60,150) * sign; 
topAnimation.To = Canvas.GetTop(rectangle) + rand.Next(60, 150) * sign; 

// Store a reference to the square that's being animated. 
previousRectangle = rectangle; 

// Start the animation. 
squareMoveStoryboard.Begin();
