Change name of parameter in action

Question

i have project with Map Route (that's all):

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

and I have method in controller:

public ViewResult List(int id = 1)
{
  ...
}

and in List.cshtml:

@Html.ActionLink(i.ToString(), "List", "Product", new { id = i }, null)

but i want to change id to page, but not change it in RouteConfig.cs, i think that's some attribute which can config my route for action. I want this solution:

@Html.ActionLink(i.ToString(), "List", "Product", new { page = i }, null)

and

[maybe here I can add my specify route?]
public ViewResult List(int page = 1)
{
  ...
}

You can use attribute routing to override the convention.

First make sure attribute routing is enabled:

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.MapMvcAttributeRoutes();   

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

Then add appropriate attribute to your controller method, for example:

[Route("YourControllerName/List/{page?}")]
public ViewResult List(int page = 1)
{
    ...
}

Question mark makes the page parameter optional.

If it's a default controller and action

[Route("")]
[Route("YourControllerName/List/{page?}")]
public ViewResult List(int page = 1)
{
    ...
}
