How to map a route for /News/5 to my news controller

Question

I am trying to identify how to map a route for /News/5 to my news controller.

This is my NewsController:

public class NewsController : BaseController
{
    //
    // GET: /News

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

}

This is my Global.asax.cs rule:

        routes.MapRoute(
            "News", // Route name
            "{controller}/{action}/{id}", // URL with parameters
            new { controller = "News", action = "Index", id = -1 } // Parameter defaults
        );

I try to go to /News/5 but I receive a resource not found error, however when going to /News/Index/5 it works?

I have tried just {controller}/{id} but that just produced the same issue.

Thanks!

Answer 1

Your {controller}/{id} route was correct but you problaby registered it AFTER the other route. In the route list it searches top down and the first match it finds wins.

To help steer routing I would suggest creating route constraints for this to ensure that #1 the controller exists and #2 the {id} is a number.

See this article

Mainly:

 routes.MapRoute( 
        "Index Action", // Route name 
        "{controller}/{id}", // URL with parameters EDIT: forgot starting "
        new { controller = "News", action = "Index" },
        new {id= @"\d+" }
    );
