Here is the sample:

using System;

using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Routing;
 
   public static class RouteExtensions
   {
     
   public static string GetUrlForRoute(this System.Web.UI.Page page, string routeName, RouteValueDictionary parameters)

         {
             if (routes == null)
             {
                 throw new ArgumentNullException("routes");
             }
             if (url == null)
             {
                 throw new ArgumentNullException("url");
             }
             IgnoreRouteInternal internal3 = new IgnoreRouteInternal(url);
             internal3.Constraints = new RouteValueDictionary(constraints);
             IgnoreRouteInternal item = internal3;
             routes.Add(item);
         }
 
         public static Route MapRoute(this RouteCollection routes, string name, string url, string physicalFile)

         public static Route MapRoute(this RouteCollection routes, string name, string url, string physicalFile, object defaults, object constraints, string[] namespaces)
         {
             if (routes == null)
             {
                 throw new ArgumentNullException("routes");
             }
             if (url == null)
             {
                 throw new ArgumentNullException("url");
             }
             if (physicalFile == null)
             {
                 throw new ArgumentNullException("physicalfile");
             }
             Route route2 = new Route(url, new PageRouteHandler(physicalFile));
             route2.Defaults = new RouteValueDictionary(defaults);
             route2.Constraints = new RouteValueDictionary(constraints);
             Route item = route2;
             if ((namespaces != null) && (namespaces.Length > 0))
             {
                 item.DataTokens = new RouteValueDictionary();
                 item.DataTokens["Namespaces"] = namespaces;
             }
             routes.Add(name, item);
             return item;
         }
 
         // Nested Types
         private sealed class IgnoreRouteInternal : Route
         {
             // Methods
             public IgnoreRouteInternal(string url)
                 : base(url, new StopRoutingHandler())
             {
             }
 
             public override VirtualPathData GetVirtualPath(RequestContext requestContext, RouteValueDictionary routeValues)
             {
                 return null;
             }
         }
     }

So, how do you use these methods?

These extensions add a few simple methods:

MapRoute

Stolen shamelessly from MVC. These methods provide a shortcut to defining Routes for WebForms.

RouteCollection.MapRoute(string name, string url, string physicalFile);

For example to map a simple route you can now do:

RouteTable.Routes.MapRoute(“ProductDetailsRoute”, “products/{productid}”, “~/ProductDetails.aspx”);

Also has a couple of variants allowing for defining defaults etc…

RouteCollection.MapRoute(string name, string url, string physicalFile, object defaults);

RouteCollection.MapRoute(string name, string url, string physicalFile, object defaults, string[] namespaces);

GetRouteForUrl

Page.GetUrlForRoute(string routeName, RouteValueDictionary parameters);

Using a specifically named route and RouteValueDictionary containing a number of parameters will give you back a string containing the Url to use. REALLY useful in databound apps!

For example:

<asp:hyperlink ID="HyperLink1" runat="server"  NavigateUrl='<%# Page.GetUrlForRoute("ProductDetailsRoute",new RouteValueDictionary( new {productid= Eval("ProductID")}))%>'  Text="Details"></asp:hyperlink>

Page.GetUrlForRoute(RouteValueDictionary parameters);

Same thing, but auto-matches the RouteValueDictionary parameters against a route…

IgnoreRoute

Allows you to define urls which should not be tried for matches against routes (can be useful for upgrading WebForms apps)

RouteCollection.IgnoreRoute(string url);

RouteCollection.IgnoreRoute(string url, object constraints);
