How to Get Fully Qualified Route Urls from GetRouteUrl

by Updated June 10, 2011

The new Routing features in ASP.NET 4.0 are pretty awesome.  However, one issue I ran into recently was trying to get the fully qualified urls from Page.GetRouteUrl as string urls to be used in emails messages.  Unfortunately, I wanted something that worked both on the localhost development server, and on the production server.  So I ended up creating a RouteUrlToFullUrl method which will get the route url and turn it into a fully qualified url, to be used as url string in emails or when you just want the full url.

The RouteUrlToFullUrl below is in class that I call Utilities.cs

    /// 
    /// Get route url and turn it into full url, to use in emails or when you need the full url
    /// 
    public static string RouteUrlToFullUrl(string route)
    {
        if(string.IsNullOrEmpty(route))
        {
            return route;
        }

        // *** Is it already an absolute Url?    
        if (route.IndexOf("://") > -1)
            return route;

        HttpContext context = HttpContext.Current;
            return String.Concat(context.Request.Url.Scheme, "://", context.Request.Url.Authority, route);
    }

 I then use the RouteUrlToFullUrl below, to get a route's fully qualified url:

string articleUrl = Utilities.RouteUrlToFullUrl(Page.GetRouteUrl("ArticleStory", new { pathname = Page.RouteData.Values["pathname"] }));

This works with both the localhost and on a production server to get the full correct domain url.  

NOTE: 'Utilities' is just the class where the RouteUrlToFullUrl function is located in, but you can surely place RouteUrlToFullUrl anywhere in your code project.

For a while I wasn't sure how to access GetRouteUrl from an .ashx IHttpHandler page. I wanted to access route url's setup in the Global.asax file to be used in files like rss.ashx, instead of having to hard codes the page URL's in my .ashx pages. Well,...  more »
