Question

I need to build a URL for self-ping action. I want to initialize that URL from Application_Start, which doesn’t have HttpContext (on ISS 7.0 integrated mode).

I have code to build absolute Action URL using HttpContext, now I need the same but use HttpRuntime instead.

using System;
using System.IO;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;

class Program
{
    static void Main()
    {
        RouteTable.Routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        RouteTable.Routes.MapRoute(
            "Default",
            "{controller}/{action}/{id}",
            new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );

        var request = new HttpRequest("/", "http://foo.com", "");
        var response = new HttpResponse(new StringWriter());
        var httpContext = new HttpContext(request, response);
        var httpContextBase = new HttpContextWrapper(httpContext);
        var routeData = new RouteData();
        var requestContext = new RequestContext(httpContextBase, routeData);
        var urlHelper = new UrlHelper(requestContext, RouteTable.Routes);

        var url = urlHelper.Action("Index", "Home", new { id = "123" }, "http");
        Console.WriteLine(url);
    }
}
