how to route url having QueryString to specific ActionResult of Controller

Question

I am working on ASP.NET MVC 3 in C# and I want to route the URL consisting of QueryString to desired controller and action Method. URL will be like localhost:44578/HVAC/?pos=installer I want to route this. I don't know how to do that. I am new to MVC.

default route in RouteConfig is

routes.MapRoute(
                name: "Default",
                url: "{siteName}/{controller}/{action}/{id}",
                defaults: new { controller = "SeoTree", 
                action = "Index", id = UrlParameter.Optional }
            );

I want to create new Map route which routes the url to Contoller = "SeoTree" ,action ="PositionInAll"

Answer 1

just map the route as you wanted like:

routes.MapRoute("Custom",
    "{controller}/{action}/{pos}",
    new { controller = "seoTree", action = "PositionInAll"},
    new { pos = @"\d+" }
    );
