Gets a collection of objects that derive from the RouteBase class.
Assembly: System.Web (in System.Web.dll)
Routes are URL patterns that are used for processing requests and that can be used to construct URLs dynamically. The property is a static property (Shared in Visual Basic) that represents all the objects that are used to specify how a URL request is matched to a class that handles the request. To specify a route, you add the route definition to the property. Typically, you add routes to the property from an event handler for the Application_Start event in the Global.asax file.
When an ASP.NET application handles a request, the application iterates through the collection of routes in the property to find the route that matches the format of the URL request. The order of the routes that you add to the property is significant, because the application uses the first route in the collection that matches the URL.
