ASP.NET (C#) Question

Dynamic routing action name in ASP.NET MVC

I would like to create a dynamic routing to a URL like following:

http://localhost:51577/Item/AnyActionName/Id


Please note that the controller name is static and doesn't need to be dynamic. On the other hand, I need to have the action name part dynamic so that whatever is written in that part of URL, I would redirect the user to the
Index
action inside of
Item
controller.

What I have tried so far is:

public static void RegisterRoutes(RouteCollection routes)
{
routes.MapRoute(
"Items",
"Item/{action}/{id}",
new { controller = "Item", action = "Index", id = UrlParameter.Optional });
}


And when I build my app I get a following error:


The resource cannot be found.


Edit:

Here is my
Global.asax
file and the
routeconfig.cs
file:

public class MvcApplication : System.Web.HttpApplication
{

protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
}
}


And here's the content of the
RouteConfig.cs
file with the answer that @Nkosi provided:

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: "Items",
url: "Item/{id}/{*slug}",
defaults: new { controller = "Item", action = "Index", slug = UrlParameter.Optional }
);
}
}

Answer

What you are referring to in your question is called a slug.

I answered a similar question here for web api

Web api - how to route using slugs?

With the slug at the end the route config would look like this

public static void RegisterRoutes(RouteCollection routes) {

    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    routes.MapRoute(
        name: "Items",
        url: "Item/{id}/{*slug}",
        defaults: new { controller = "Item", action = "Index", slug = RouteParameter.Optional }
    );

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

}

which could match an example controller action...

public class ItemController : Controller {
    public ActionResult Index(int id, string slug = null) {
        //...
    }
}

the example URL...

"Item/31223512/Any-Item-Name"

would then have the parameters matched as follows...

  • id = 31223512
  • slug = "Any-Item-Name"

And because the slug is optional, the above URL will still be matched to

"Item/31223512"
