MVC routing with multiple parameter with different parameter name

Question

In my home controller, I have 3 Action methods. which is give below.

        public ActionResult Index(int id)
        {
            return View();
        }


        public ActionResult Index2(int did,int docType)
        {
            return View();
        }


        public ActionResult Index3(int uid,int docId,int typeId)
        {
            return View();
        }

As I had given diffrent parameter name in each action methods so I have to change in Route.config.

I have Done this

Method 1

routes.MapRoute(
                name: "Home",
                url: "{controller}/{action}/{did}/{docType}",
                defaults: new { controller = "Home", action = "Index2", did = UrlParameter.Optional, docType = UrlParameter.Optional }
            );
            routes.MapRoute(
                name: "Home",
                url: "{controller}/{action}/{uid}/{docId}/{typeId}",
                defaults: new { controller = "Home", action = "Index3", uid = UrlParameter.Optional, docId = UrlParameter.Optional, typeId = UrlParameter.Optional }
            );
            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );

but it is giving me exception like

Home' is already in the route collection. Route names must be unique

So I have change it to like this

Method 2

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

When I hit Url like

http://localhost:50958/Home/Index/2

http://localhost:50958/Home/Index2/2/3

http://localhost:50958/Home/Index3/2/3/4

it throwing me exception.

This is Solution.

As suggested by Stephen Muecke

 routes.MapRoute(
                name: "Admin",
                url: "{controller}/{action}/{did}/{docType}",
                defaults: new { controller = "Home", action = "Index2", did = UrlParameter.Optional, docType = UrlParameter.Optional }
            );
            routes.MapRoute(
                name: "User",
                url: "{controller}/{action}/{uid}/{docId}/{typeId}",
                defaults: new { controller = "Home", action = "Index3", uid = UrlParameter.Optional, docId = UrlParameter.Optional, typeId = UrlParameter.Optional }
            );
            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );

Solution 1

As I had given same name to all route. and route name must be unique, now i have rename the route with different name.

routes.MapRoute(
                name: "Admin",
                url: "{controller}/{action}/{did}/{docType}",
                defaults: new { controller = "Home", action = "Index2", did = UrlParameter.Optional, docType = UrlParameter.Optional }
            );
            routes.MapRoute(
                name: "User",
                url: "{controller}/{action}/{uid}/{docId}/{typeId}",
                defaults: new { controller = "Home", action = "Index3", uid = UrlParameter.Optional, docId = UrlParameter.Optional, typeId = UrlParameter.Optional }
            );
            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );

Solution 2

Route name should be unique, You have two routes with same name: "Home"
