using UriTemplate

Copied from MSDN:

The UriTemplateTable class provides a mechanism for managing a collection of UriTemplate objects. This makes it easy to call Match on the table to find all templates that match the supplied Uri. Alternatively, you can call MatchSingle to ensure it matches only a single UriTemplate in the table.

Uri baseUri = new Uri("http://contoso.com/bookmarkservice");
UriTemplate uriTemplate = new UriTemplate( "users/{username}/bookmarks/{id}");

// generate a new bookmark URI
Uri newBookmarkUri = uriTemplate.BindByPosition(baseUri, "skonnard", "123");

// match an existing bookmark URI
UriTemplateMatch match = uriTemplate.Match(baseUri, newBookmarkUri);
System.Diagnostics.Debug.Assert(match != null);
Console.WriteLine(match.BoundVariables["username"]);
Console.WriteLine(match.BoundVariables["id"]);
