ASP.NET MVC4 Custom routing

asp.net-mvc-4, asp.net-mvc-routing

Solution

       routes.MapRoute(
            name: "ArticleList",
            url: "{controller}/{category}/{page}",
            defaults: new
            {
                category = UrlParameter.Optional,
                page = 1,
                action = "Index"
            },
            constraints: new
            {
                controller = "Articles"
            }
       );


        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );

EDIT

I should have added this to the answer but I was in a hurry:

- Register your custom routes first, the more custom the more priority they have.

In the example above using the constraints or hard-coding the route produces the same result. Constraints are more flexible because you can use regex to restrict the controllers/actions/parameters values that your route is for. For instance, if you add a new route that uses the /category/page pattern your can then modify the controller constraint accordingly:

constraints: new { controller = @"^(Articles|AnotherController)$" }

Problem

I want to create simple blog engine. For fancy and clean url I'd like to use routing mechanism implemented in MVC4. I added to RouteConfig.cs this lines: ``` 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 } ); routes.MapRoute( name: "ArticleList", url: "Articles/{category}/{page}", defaults: new { controller = "Articles", category = UrlParameter.Optional, page = 1 }); } } ``` And if I write in web browser url: ``` http://localhost:6666/Articles/SomeCategory/3 ``` I want to move to this controller: ``` public class ArticlesController : ControllerBase<IHomeService> { public ActionResult Index(string category, int page = 0) { return View("~/Views/Article/Articles.cshtml"); } } ``` with parameters category = "SomeCategory" and page = 1. All I recieve is Server Error in '/' Application. The resource cannot be found. What is wrong?
