How to create route mappings for 2 different parameters

I am very new to MVC concepts and am working with MVC4 and noticed an issue. Any help would be greatly appreciated.

I have 2 different methods in my controller. One requires int parameter "id" and the other requires int parameter "userId". As suggested in some articles, I am registering a separate route map for each parameter name in Global.asax.cs - RegisterRouteMapping method. According to these articles its all required to be done to support 2 parameter names.

The problem is: When I type url Controller/GetValues/5 it works and I get 5 as "id" in GetValues method. But when I type Controller/Details/10 the "userId" is null in the Detail method.

If I interchange the mappings and put the one for userId on top, I get correct value for "userId" in Details method but "id" will be null in the GetValues method.

Following are the two methods in controller

public ActionResult GetValues(int? id)

{ return View(); }

public ActionResult Details(int? userId)

{ return View (); }

Following is code from Global.asax

public static void RegisterRoutes(RouteCollection routes)

{

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

//Add the default route for id

routes.MapRoute( "Default", // Route name

"{controller}/{action}/{id}", // URL with parameters

new { controller = "Home", action = "Index", id = UrlParameter.Optional }, // Parameter defaults

new String[] { namespaces }

);

//Add the default route for userId

routes.MapRoute( "Default_user", // Route name

"{controller}/{action}/{userId}", // URL with parameters

new { controller = "Home", action = "Index", userId = UrlParameter.Optional }, // Parameter defaults

new String[] { namespaces } ); }

Thanks in advance

Re: How to create route mappings for 2 different parameters

your routing will not work. routing picks the first match. route matching is pattern matching only

{controller}/{action}/{id}

with default values for controlelr, action, and option id, this pattern matches all the follwing.

/
/somevalue
/somevalue/
/somevalue/anothervalue
/somevalue/anothervalue/
/somevalue/anothervalue/yetanothervalue
/somevalue/anothervalue/yetanothervalue?a=b

there is no pattern that will fail to match here that will match

{controller}/{action}/{id}

as they are the same pattern.

SJMVC
"{controller}/{action}/{userId}"

SJMVC
"{controller}/{action}/{id}",

is the same route! For example, if you have

a/b/c , both are satisfied. MVC picks first route that satisfies and assign parameters

SJMVC
But when I type Controller/Details/10 the "userId" is null in the Detail method.

SJMVC
public ActionResult Details(int? userId)

put

public ActionResult Details(int? id)

as in the route registration.
