ActionLink is showing query string instead of URL parameters

问题

My question is very similar other questions. When using an ActionLink in MVC .Net 4.5, I am getting a query string for one parameter, instead of just a URL path. I tried the solution HERE, but it did not work.

CODE-

Inside RouteConfig.cs -

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

  routes.MapRoute(
            name: "MyControllerRoute",
            url: "{controller}/{action}/{id}/{description}",
            defaults: new { controller = "MyController", action = "MyAction", id = UrlParameter.Optional, description = UrlParameter.Optional }
        );

Inside HomeController.cs -

public ActionResult Index(){
  --do stuff--
   return View();
}

Inside MyController.cs -

public ActionResult Vote(int id, string description){
   --do stuff--
   return View();
}

Inside Index.cshtml

@Html.ActionLink(
       "This is stuff", 
       "MyAction", 
       "MyController", 
       new { id = 123, description = "This-is-stuff"  }, 
       null)

GETTING THIS RESULT - (NOT WHAT I WANT)

<a href="/MyController/MyAction/123?description=This-is-stuff">This is stuff</a>

DESIRED RESULT - (HOW CAN I GET THIS?)

<a href="/MyController/MyAction/123/This-is-stuff">This is stuff</a>

回答1:

You need to swap the order of the routes. I would also recommend that you use the controller name (and optionally the action name) in the url definition to prevent possible conflicts with other routes. In addition, only the last parameter can be marked as UrlParameter.Optional (otherwise if only one of the parameters were provided, the route would be ignored and the url would revert to using query string values). Your definitions should be (in order)

routes.MapRoute(
    name: "MyControllerRoute",
    url: "MyController/MyAction/{id}/{description}",
    defaults: new { controller = "MyController", action = "MyAction" }
);

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