【ASP.NET】System.Web.Routing - Route Class

Provides properties and methods for defining a route and for obtaining information about the route.

ex:

void Application_Start(object sender, EventArgs e)
{
    RegisterRoutes(RouteTable.Routes);
}

public static void RegisterRoutes(RouteCollection routes)
{
    routes.Add(new Route
    (
         "Category/{action}/{categoryName}"
         , new CategoryRouteHandler()
    ));
}

The Route class enables you to specify how routing is processed in an ASP.NET application. You create a Route object for each URL pattern that you want to map to a class that can handle requests that correspond to that pattern. You then add the route to the Routes collection. When the application receives a request, ASP.NET routing iterates through the routes in the Routes collection to find the first route that matches the pattern of the URL.
