Question

I’m using ASP.Net MVC 3 and am trying to pass an email address as a parameter in a URL like this:

http://www.myapp.co.uk/customers/changedetails/[e-mail]

The parameter value is null when passed in. If I use parameters then it works;

http://www.myapp.co.uk/customers/changedetails/?email=[e-mail]

My controller looks like this:

    public class CustomerController {

    [HttpGet]
    public ViewResult ChangeDetails(string email)
    {
      var model = GetModel(email);
       return View(model);
    }
    }

My register routes looks like this:

   public static void RegisterRoutes(RouteCollection routes)
   {
      routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
      routes.MapRoute(
          "Default",
          "{controller}/{action}/{id}",
          new { controller = "Home", action = "Index", id = UrlParameter.Optional }
      );
   }

What am I missing to be able to use the email as the {id} parameter (http://www.myapp.co.uk/customers/changedetails/[e-mail])?:

You need to add another route:

      routes.MapRoute(
          "ChangeEmail",
          "customers/changedetails/{email}",
          new { controller = "Customers", action = "ChangeDetails", email = UrlParameter.Optional }
      );

The URL parameter name needs to match the action method parameter name.
