silverlight,frame page QueryString及uri映射

silverlight中frame相当一个框架似的，可提供在不同*.xaml之间的导航，frame显示的内容就是一个一个的page

类似*.aspx一样。请注意frame导航的是page而不是userControl,所以在新建的时候记得选Silveright Page.

在不同page导航的时候可以像aspx一样传递QueryString不过写法有点改变而已。

uri映射就不多说了，其实也是就虚拟的uri.

示例代码：

MainPage.xaml

<UserControl 
    xmlns:my="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation"  
    xmlns:windowsNav="clr-namespace:System.Windows.Navigation;assembly=System.Windows.Controls.Navigation"

    d:DesignHeight="300" d:DesignWidth="400">

    <Grid x:Name="LayoutRoot" Background="White">
