<form id="form1" runat="server">
        <div>
            <strong>RSS Feed:</strong><br />

            <asp:Button ID="btnRSSFeed" runat="server" Text="Get RSS Feed" OnClick="btnRSSFeed_Click" Style="height: 26px" />

protected void btnRSSFeed_Click(object sender, EventArgs e)
        {
            var posts = GetFeeds(txtrss.Text);
            StringBuilder sb = new StringBuilder();
            sb.Append("<p style='font-weight:larger'><b>Latest News Content</b></p>");
            foreach (var item in posts)
            {
 
                sb.Append("<b>Title: </b>" + item.title);
                sb.Append("<br />");
                sb.Append("<b>Description: </b>" + item.desc);
                sb.Append("<br />");
                sb.Append("<b>Article Link: </b><a target='_blank' href='" + item.contentlink + "'>" + item.contentlink + "</a>");
                sb.Append("<br />");
                sb.Append("<b>Published Date: </b>" + item.pubDate);
                sb.Append("<br />");
                sb.Append("------------------------------------------------------------------------------------------------------------");
                sb.Append("<br />");
 
            }
            HttpContext.Current.Response.Write(sb);  
 
        }
        public static IEnumerable<NewsRead> GetFeeds(string url)
        {
            XDocument rssfeedxml;
            XNamespace namespaceName = "http://www.w3.org/2005/Atom";
            rssfeedxml = XDocument.Load(url);
            StringBuilder rssContent = new StringBuilder();
            var list = (from descendant in rssfeedxml.Descendants("item")
                        select new NewsRead
                        {
                            title = descendant.Element("title").Value,
                            desc = descendant.Element("description").Value,
                            contentlink = descendant.Element("link").Value,
                            pubDate= descendant.Element("pubDate").Value,
                        });
            return list.ToList();
        }  
 

Run the application and paste the RSS feed Link URL in the TextBox and Click the Get RSS Feed Button.
