asp.net mvc - ActionLink to show parameters in URL instead of querystring mvc -

i need url http://localhost:53249/admin/editposts/1/edit unfortunately m getting query string in url http://localhost:53249/admin/editposts?id=1&operation=edit

this actionlink(anchor tag)

<td>@html.actionlink(@posts.title, "editposts", "admin", new { id = posts.id, operation="detail" }, null)</td> 

this route config:

 public static void registerroutes(routecollection routes)         {             //routes.ignoreroute("{resource}.axd/{*pathinfo}");              routes.mapmvcattributeroutes();             routes.maproute(              name: "admin",              url: "admin/editposts/{id}/{operation}",              defaults: new { controller = "admin", action = "editposts"}          );              routes.maproute(                 name: "default",                 url: "{controller}/{action}/{id}",                 defaults: new { controller = "home", action = "index", id = urlparameter.optional }             );          } 

in case mixing action , operation.

i suggest use url this:

http://localhost:53249/admin/posts/1/edit 

because way indicate action, edit, posts objects, , edit action, not operation, following standard rest.

to use url suggested must change maproute to:

routes.maproute(     name: "admin",     url: "admin/posts/{id}/{action}",     defaults: new { controller = "posts", action = "details" } //details action default );
