Question

I have two routes defined thus:

//Custom route for legacy admin page
      routes.MapPageRoute(
       "LocaliseRoute",                         // Route name
       "Admin/Localise",                // URL
       "~/Views/Admin/Localise.aspx"   // File
       );

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

both the following GETs work fine:

http://pegfect.local/Admin/PegModelUpload
http://pegfect.local/Admin/Localise

However, the form action of the former is /Admin/Localise?action=UploadPegModel&controller=Admin

resulting in an expression of “WTF?!”

the code for the form is:

@using (Html.BeginForm("UploadPegModel", "Admin", FormMethod.Post, new { enctype = "multipart/form-data", onsubmit = "return validateForm();" }))
{
  <input type='file' name='file' id='file' />
  <input type="submit" value="submit" />
}
