Creating and Registering a Simple Route
Once you have a URL pattern in mind, you can use it to define a route. Routes are defined in the RouteConfig.cs file,
which is in the App_Start project folder. You can see the initial content that Visual Studio defines for this file in Listing 15-5.
Listing 15-5. The Default Contents of the RouteConfig.cs File
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;
namespace UrlsAndRoutes {
public class RouteConfig {
public static void RegisterRoutes(RouteCollection routes) {
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
}
}
}
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index",
id = UrlParameter.Optional }
);
The static RegisterRoutes method that is defined in the RouteConfig.cs file is called from the
Global.asax.cs file, which sets up some of the core MVC features when the application is started. You can see the
default contents of the Global.asax.cs file in Listing 15-6, and I have highlighted the call to the
RouteConfig.RegisterRoutes method, which is made from the Application_Start method.
Listing 15-6. The Default Contents of the Global.asax.cs File
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;
namespace UrlsAndRoutes {
}
public class MvcApplication : System.Web.HttpApplication {
protected void Application_Start() {
AreaRegistration.RegisterAllAreas();
RouteConfig.RegisterRoutes(RouteTable.Routes);
}
}
The Application_Start method is called by the underlying ASP.NET platform when the MVC application is first
