Remarks

You use the UriMapper class to store the collection of UriMapping objects to use for converting a requested URI to another URI. You define the UriMapper object and its collection of UriMapping objects for a frame by assigning the UriMapper object to the UriMapper property of the frame.

The UriMappings property contains the collections of mapping objects. The MapUri method converts a requested URI to the new URI based on the mappings you defined in objects you added to the UriMappings property.

Typically, you will not need to programmatically call the MapUri method. The Silverlight framework automatically calls the MapUri method for each request when you have added an instance of the UriMapper class to your application.

Examples

The following example shows an instance of UriMapper that is defined within a frame named ContentFrame. The element contains a collection of UriMapping objects.

<sdk:Frame 
       x:Name="ContentFrame" 
       Style="{StaticResource ContentFrameStyle}" 
       Source="/Home" 
       Navigated="ContentFrame_Navigated" 
       NavigationFailed="ContentFrame_NavigationFailed">
    <sdk:Frame.UriMapper>
        <sdk:UriMapper>
            <sdk:UriMapping 
                Uri="/ProductDetail/{productid}" 
                MappedUri="/Views/ProductDetail.xaml?ProductId={productid}"/>
            <sdk:UriMapping 
                Uri="/Reports/{type}/{selection}" 
                MappedUri="/Views/ReportsPage.xaml?type={type}&amp;selection={selection}"/>
            <sdk:UriMapping 
                Uri="/{pageName}" 
                MappedUri="/Views/{pageName}.xaml"/>
        </sdk:UriMapper>
    </sdk:Frame.UriMapper>
</sdk:Frame>
