[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

When overridden in a derived class, converts a requested uniform resource identifier (URI) to a new URI.

Namespace:  System.Windows.Navigation
Assembly:  Microsoft.Phone (in Microsoft.Phone.dll)


Public MustOverride Function MapUri ( _
    uri As Uri _
) As Uri
public abstract Uri MapUri(
    Uri uri


  • uri
    Type: System..::.Uri
    The original URI value to be mapped to a new URI.

Return Value

Type: System..::.Uri
A URI to use for the request instead of the value in the uri parameter.


To implement customized URI mapping logic, you override the MapUri method and specify in that method how the URI is converted.

The MapUri method of the UriMapper class overrides MapUri and provides a basic implementation for converting one URI to another URI.
