Consuming RSS Feed in MVC ASP.NET

Introduction

In this article, I will build an MVC application that will consume an RSS feed. I will modify my previous project for RSS Feed. Follow these steps.

Select the "Controllers" Folder and then right click and click on Controller as shown below:

Press Add, and RssFeedController class will be created as shown below. The SyndicationFeed class from System.ServiceModel.Syndicatation makes it easy to work with RSS Feed. The code below uses an RSS feed from weblogs.asp.net to display ASP.NET weblogs on a page.

using System.ServiceModel.Syndication;        // add a System.ServiceModel.Web.dll reference 
public class RSSFeedController : Controller
{
        public ActionResult RSSFeed() 
       {
          string strFeed = "http://weblogs.asp.net/aspnet-team/rss.aspx"; 
          using (XmlReader reader = XmlReader.Create(strFeed)) 
         { 
                  SyndicationFeed rssData = SyndicationFeed.Load(reader); 
                 return View(rssData); 
         }
     }
}

Repeat the above step 2, and Add RSSFeed view in Views\RSSFeed folder. Add the following code in RSSFeed view.

<%@ Page Title="" Language="C#" 

MasterPageFile="~/Views/Shared/Site.Master" 

Inherits="System.Web.Mvc.ViewPage<SyndicationFeed>" %> 
<%@ Import Namespace="System.ServiceModel.Syndication"%>
<asp:Content ID="Content1" 

ContentPlaceHolderID="TitleContent" runat="server">
RSSFeed
</asp:Content> 
<asp:Content ID="Content2" 

ContentPlaceHolderID="MainContent" runat="server">
<h2>RSSFeed</h2>
<% foreach (var item in ViewData.Model.Items) 
{ 
string URL = item.Links[0].Uri.OriginalString; 
string Title = item.Title.Text; 
Response.Write(string.Format("<p>
<a href=\"{0}\"><b>{1}</b></a>", URL, Title)); 
Response.Write("<br/>" + item.Summary.Text + "</p>"); 
} %>
</asp:Content>

Now you can run the project and it will display RSS feed from weblogs.asp.net as shown below:

Summary
