How to Implement a Rss Feed Reader in C#

Included in this page:
1.) Rss feed model (which you can customized according to your needs)
2.) Rss feed reader

My Objective is to read an rss feed of a news site like google and yahoo:

For example we want to read the RSS feed of yahoo news in the Philippines:

http://ph.news.yahoo.com/rss/most-popular-most-viewed-ph.xml

Note that the model also applies to google news since they have almost the same xml structure:

<item>
  <title>Title</title>
  <pubDate>Publication date</pubDate>
  <description>Description</description>
</item>

First we need to setup a model where we will store the feed. Let's call this class RSSNews:

public class RssNews
    {
        public string Title;
        public string PublicationDate;
        public string Description;
    }

Then you need a class to read a rss feed url:

using System.Collections.Generic;
using System.Net;
using System.Data;
using System.Linq;

public class RssReader
    {
        public static List<rssnews> Read(string url)
        {
            var webResponse = WebRequest.Create(url).GetResponse();
            if (webResponse == null)
                return null;
            var ds = new DataSet();
            ds.ReadXml(webResponse.GetResponseStream());

            var news = (from row in ds.Tables["item"].AsEnumerable()
                         select new RssNews
                                    {
                                         Title = row.Field<string>("title"),
                                        PublicationDate = row.Field<string>("pubDate"),
                                        Description = row.Field<string>("description")
                                    }).ToList();
            return news;
        }
    }

*Make sure you include all the imports.

And finally, the code to call the reader, which you can place in your Page_Load event if you are working on a web app else Main method:

RssReader.Read("http://ph.news.yahoo.com/rss/most-popular-most-viewed-ph.xml");
