Silverlight多媒体与样式行为全解析

一、Silverlight动画与多媒体特性概述

在Silverlight应用开发中，我们可以通过代码实现动画效果。以下是一段用于实现矩形动画移动的代码：

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

' Choose a random direction and movement amount.
Dim rand As New Random()
Dim sign As Integer = 1
If rand.Next(0, 2) = 0 Then
    sign = -1
End If
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()
End Sub

这段代码结合了视频、交互性，能产生比其他基于浏览器的应用平台更出色的效果。
