Sitemap in Asp.Net MVC

Anonymous User 2986 10 Oct 2014

'm trying to create an automatic sitemap ActionResult that outputs a valid sitemap.xml file. The actual generation of the file is not a problem, but I can't seem to figure out how to populate the list of URL's in the system. Here is the code I have so far:

public ContentResult Sitemap()
        {
            XNamespace xmlns = "http://www.sitemaps.org/schemas/sitemap/0.9";
            XElement root = new XElement(xmlns + "urlset");
 
            using (MemoryStream ms = new MemoryStream())
            {
                using (StreamWriter writer = new StreamWriter(ms, Encoding.UTF8))
                {
                    root.Save(writer);
                }
 
                return Content(Encoding.UTF8.GetString(ms.ToArray()), "text/xml", Encoding.UTF8);
            }
        }

For instance, suppose I have two controllers, and each controller has two actions associated with them:

HelpController

· Edit

· Create

AboutController

· Company

· Management

I took a look at Maarten Balliauw's approach per likwid's comment, but it seems to be overkill for what I'm trying to do.

I've hacked together a temporary solution. I'm simply passing the controller and action names to generate the URL's. In order to generate the URL's, I'm using the following code:

    List<string> urlList = new List<string>();
    urlList.Add(GetUrl(new { controller = "Help", action = "Edit" }));
    urlList.Add(GetUrl(new { controller = "Help", action = "Create" }));
    urlList.Add(GetUrl(new { controller = "About", action = "Company" }));
    urlList.Add(GetUrl(new { controller = "About", action = "Management" }));

where GetUrl is as below:

protected string GetUrl(object routeValues)
        {
            RouteValueDictionary values = new RouteValueDictionary(routeValues);
            RequestContext context = new RequestContext(HttpContext, RouteData);
 
            string url = RouteTable.Routes.GetVirtualPath(context, values).VirtualPath;
 
            return new Uri(Request.Url, url).AbsoluteUri;
        }

This seems to do the trick for now, though I do like the idea of having actionfilter's applied to certain actions that get pulled together automatically.
