در صورتیکه طراحی شما بر اساس MVC صورت گرفته است، در کمتر از چند دقیقه و در سه مرحله میتوانید پرونده Rss و Sitemap را برای همیشه ببندید. 

پیش از تشریح مراحل، به ساختار این دو فایل توجه کنید. 

مراحل کار : 

مرحله 1. ایجاد نوع(Type) مورد نیاز برای ایجاد Xml ‌های فوق

مرحله 2 . ایجاد کنترلر XML

مرحله 3. ایجاد مسیریابی(Routing)

مرحله 1 : ابتدا یک کلاس به منظور شکل دهی به اطلاعات، بر اساس خواسته‌های xml مرتبط با RSS و Sitemap تشکیل دهید:

public class PostToXml
    {
        
        public int PostId { get; set; }

        public string title { get; set; }

        public string link { get; set; }
        
        public string description { get; set; }

        public Nullable<DateTime> pubDate { get; set; }

      
    }

مرحله 2 : یک کنترلر به نام xml ایجاد کنید و اکشن متدهای زیر را درون آن قرار دهید :

       public ContentResult RSS()
        {
            
            var items = GetRssFeed();
            var rss = new XDocument(new XDeclaration("1.0", "utf-8", "yes"),
              new XElement("rss",
                new XAttribute("version", "2.0"),
                  new XElement("channel",
                    new XElement("title", "آخرین مطالب سایت"),
                    new XElement("link", "http://" + Request.Url.Host+"/rss"),
                    new XElement("description", "آخرین مطالب سایت من"),
                    new XElement("copyright","(c)" + DateTime.Now.Year + ", نام سایت من.تمامی حقوق محفوظ است"),
                  from item in items
                  select
                  new XElement("item",
                    new XElement("title", item.title),
                    new XElement("description", item.description),
                    new XElement("link", item.link),
                    new XElement("pubDate", item.pubDate)

                  )
                )
              )
            );
            return Content(rss.ToString(), "text/xml");
        }



        public ContentResult Sitemap()
        {
            XNamespace ns = "http://www.sitemaps.org/schemas/sitemap/0.9";
            var items = GetLinks();
            var sitemap = new XDocument(new XDeclaration("1.0", "utf-8", "yes"),
                new XElement(ns + "urlset",
                    from item in items
                    select
                    new XElement("url",
                      new XElement("loc", item.link),
                      new XElement("changefreq", "monthly"),
                      new XElement("priority", "0.5")
                      )
                    )
                  );
            return Content(sitemap.ToString(), "text/xml");
        }


        public IEnumerable<PostToXml> GetRssFeed()
        {
          // یک کوئری که لیستی از تایپ مشخص شده به ما بدهد
        }

         public IEnumerable<PostToXml> GetLinks()
        {
            // یک کوئری که لیستی از تایپ مشخص شده به ما بدهد
        }

این کنترلر دارای دو اکشن متد Rss و Sitemap است و این اکشن‌ها وظیفه‌ی ایجاد فایل‌های Xml را به عهده دارند. مواد اولیه این xml ‌ها از دو متد GetRssFeed و GetLinks تهیه می‌شوند. ما این مواد را در تمپلیت Rss و Sitemap جایگذاری خواهیم کرد. (به کمک دو اکشن متد Rss و Sitemap )

کافیست لیستی از مواردی را که می‌خواهیم در Rss یا Sitemap ثبت شوند، تهیه کنیم. این لیست بر اساس شکل تنظیم دیتابیس و مسیریابی سایت، می‌تواند پیچیده و یا ساده باشد. (به کمک کوئری گرفتن با linq و یا اضافه کردن مستقیم آدرس‌ها به لیست و یا ترکیبی از هر دو مورد) برای درک بهتر موضوع، لطفا تصویر موجود در ابتدای مقاله را مشاهده نمایید.

مرحله 3 : در مرحله آخر کافیست دو مورد زیر را به فایل RoutConfig.cs بیافزایید: 

routes.MapRoute(
              "Sitemap", "sitemap",
              new { controller = "XML", action = "Sitemap" });
 routes.MapRoute(
              "RSS", "rss",
               new { controller = "XML", action = "RSS" });

به کمک آدرس‌های زیر می‌توانید به آنچه که تهیه کرده‌اید دسترسی داشته باشید :

http://domain.com/rss
http://domain.com/sitemap
