I am trying to get my URLs in files/id format. I am guessing I should have two Index methods in my controller, one with a parameter and one with not. But I get this error message in browser below.
Anyway here is my controller methods:
public ActionResult Index()
{
return Content("Index ");
}
//
// GET: /Files/5
public ActionResult Index(int id)
{
File file = fileRepository.GetFile(id);
if (file == null) return Content("Not Found");
else return Content(file.FileID.ToString());
}
Error:
Server Error in '/' Application.

Updated Code:
public ActionResult Index(int? id)
{
if (id.HasValue)
{
File file = fileRepository.GetFile(id.Value);
if (file == null) return Content("Not Found");
else return Content(file.FileID.ToString());
}
else
return Content("Index");
}
It's still not the thing I want. URLs have to be in files?id=3 format. I want files/3
routes from global.asax
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index",
id = UrlParameter.Optional } // Parameter defaults
);
//files/3
//it's the one I wrote
routes.MapRoute("Files", "{controller}/{id}",
new { controller = "Files", action = "Index", id = UrlParameter.Optional}
);
I tried adding a new route after reading Jeff's post but I can't get it working. It still works with files?id=2 though.
