How do I route a URL with a querystring in ASP.NET MVC?

Question

I\'m trying to setup a custom route in MVC to take a URL from another system in the following format:

../ABC/ABC01?Key=123&Group=456

The 01

When defining routes, you cannot use a / at the beginning of the route:

routes.MapRoute("OpenCase",
    "/ABC/{controller}/{key}/{group}", // Bad. Uses a / at the beginning
    new { controller = "", action = "OpenCase" },
    new { key = @"\d+", group = @"\d+" }
    );

routes.MapRoute("OpenCase",
    "ABC/{controller}/{key}/{group}",  // Good. No / at the beginning
    new { controller = "", action = "OpenCase" },
    new { key = @"\d+", group = @"\d+" }
    );

Try this:

routes.MapRoute("OpenCase",
    "ABC/{controller}/{key}/{group}",
    new { controller = "", action = "OpenCase" },
    new { key = @"\d+", group = @"\d+" }
    );

Then your action should look as follows:

public ActionResult OpenCase(int key, int group)
{
    //do stuff here
}

It looks like you're putting together the stepNo and the "ABC" to get a controller that is ABC1. That's why I replaced that section of the URL with {controller}.

Since you also have a route that defines the 'key', and 'group', the above route will also catch your initial URL and send it to the action.
