I might be missing something here, but in ASP.NET MVC 4, I can't get the following to work.
Given the following controller:
public class HomeController : Controller
{
public ActionResult Index()
{
return View();
}
[HttpPost]
public ActionResult Index(string order1, string order2)
{
return null;
}
}
and it's view:
@{
ViewBag.Title = "Home";
}
@using (Html.BeginForm())
{
@Html.TextBox("order1")<br />
@Html.TextBox("order2")
<input type="submit" value="Save"/>
}
When start the app, all I get is this:
The current request for action 'Index' on controller type
'HomeController' is ambiguous between the following action methods:
System.Web.Mvc.ActionResult Index() on type
ViewData.Controllers.HomeController System.Web.Mvc.ActionResult
Index(System.String, System.String) on type
ViewData.Controllers.HomeController
Now, in ASP.NET MVC 3 the above works fine, I just tried it, so what's changed in ASP.NET MVC 4 to break this?
OK there could be a chance that I'm doing something silly here, and not noticing it.
EDIT:
I notice that in the MVC 4 app, the Global.asax.cs file did not contain this:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
}
which the MVC 3 app does, by default. So I added the above to the MVC 4 app but it fails with the same error. Note that the MVC 3 app does work fine with the above route. I'm passing the "order" data via the Request.Form.
EDIT:
In the file RouteConfig.cs I can see RegisterRoutes is executed, with the following default route:
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional });
I still get the original error, regards ambiguity between which Index() method to call.
