urls on asp.net mvc 5

One possibility would be to use the Data Annotation [Route] for this, first, you have to activate MapMvcAttributeRoutes() in the class RouteConfig.cs

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {

        routes.MapMvcAttributeRoutes();

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

Then, it would be enough to use [Route] in the method where you want to customize your route

No parameters

[Route("~/ControladorA/el-ejemplo")]
     public ViewResult metodoEjemplo()
     {
         return View();
         //En este ejemplo la ruta sería http://localhost/ControladorA/el-ejemplo
     }

With Parameters

[Route("~/Pelicula/{idpelicula}")]
     public ViewResult metodoEjemplo(int idpelicula)
     {             
         return View();
         //En este ejemplo la ruta sería, por ejemplo  http://localhost/Pelicula/3
         //donde 3 representa el id de una película
     }

For more information on the subject you can directly see the Microsoft Documentation , since you will see different options to reach the same result, and you may find one that is more comfortable for you

You can use the attribute Route where you specify a format for your url.

For example:

public classs HomeController : Controller{
    public ActionResult Index() {
      return View();
    }
}

Normally to invoke index would be /home/index . Adding the Route attribute can change the url of that controller. For example let's say you want it to be /h-ome/index :

public classs HomeController : Controller{

   [Route("h-ome/index/")]
   public ActionResult Index() {
        return View();
   }
}

With route you can simulate subdirectories too:

[Route("home/user/start")]
public ActionResult Index()
{
  //...
}

Where the url would be /home/user/start and therefore Index would be executed.

Take a look at the documentation so you can get a good dose of the subject.

Bonus: If your action requires parameters, with Route you can make the URL more user friendly, for example, to see the user's information, normally it would be /user/info?username=einer . This can be changed to /user/einer/info :

[Route("user/{username}/info")]
public ActionResult UserInfo(string username) {
    //...
}
