我可以从Sitemap生成ASP.NET MVC路由吗？

<?xml version="1.0" encoding="utf-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
</urlset>

public class SitemapController : Controller
{
    public ActionResult Index()
    {
        var routes = RouteTable.Routes.OfType<Route>();
        var urls = new List<string>();

        foreach (var route in routes)
        {
            var url = route.Url;
            urls.Add(url);
        }

        var sitemap = new XElement("urlset",
            from url in urls
            select new XElement("url",
                new XElement("loc", url)
            )
        );

        return Content(sitemap.ToString(), "application/xml");
    }
}

@model string

@{
    Layout = null;
}

@Html.Raw(Model)
