A simple way to read an RSS feed using C#

I found a decent RSS news feed that was free (http://freenewsfeed.newsfactor.com/rss) and was looking at integrating it into my new blog design. In order to do this I wanted to create a simple class that would read an RSS feed based on a URL passed in, and I thought the best way to do this would be to first create a class I could use to store the RSS feed items. So I created the following:

    /// <summary>
    /// RSS feed item entity
    /// </summary>
    public class RssFeedItem
        /// <summary>
        /// Gets or sets the title
        /// </summary>
        public string Title { get; set; }
        /// <summary>
        /// Gets or sets the description
        /// </summary>
        public string Description { get; set; }

        /// <summary>
        /// Gets or sets the link
        /// </summary>
        public string Link { get; set; }

        /// <summary>
        /// Gets or sets the item id
        /// </summary>
        public int ItemId { get; set; }

        /// <summary>
        /// Gets or sets the publish date
        /// </summary>
        public DateTime PublishDate { get; set; }

        /// <summary>
        /// Gets or sets the channel id
        /// </summary>
        public int ChannelId { get; set; }

Next I needed a manager class that would read any RSS feed and populate a list of the above rss feed item object with the relevant data. To achieve this I created the following static class:

    /// <summary>
    /// RSS manager to read rss feeds
    /// </summary>
    public static class RssManager
        /// <summary>
        /// Reads the relevant Rss feed and returns a list off RssFeedItems
        /// </summary>
        /// <param name="url"></param>
        /// <returns></returns>
        public static List<RssFeedItem> ReadFeed(string url)
            //create a new list of the rss feed items to return
            List<RssFeedItem> rssFeedItems = new List<RssFeedItem>();

            //create an http request which will be used to retrieve the rss feed
            HttpWebRequest rssFeed = (HttpWebRequest)WebRequest.Create(url);

            //use a dataset to retrieve the rss feed
            using (DataSet rssData = new DataSet())
                //read the xml from the stream of the web request

                //loop through the rss items in the dataset and populate the list of rss feed items
                foreach (DataRow dataRow in rssData.Tables["item"].Rows)
                    rssFeedItems.Add(new RssFeedItem
                        ChannelId = Convert.ToInt32(dataRow["channel_Id"]),
                        Description = Convert.ToString(dataRow["description"]),
                        ItemId = Convert.ToInt32(dataRow["item_Id"]),
                        Link = Convert.ToString(dataRow["link"]),
                        PublishDate = Convert.ToDateTime(dataRow["pubDate"]),
                        Title = Convert.ToString(dataRow["title"])

            //return the rss feed items
            return rssFeedItems;

I was all set, all I had to do now was pass in a URL of an RSS feed, and I would be returned a list of rss feed items...

Happy rss-ing!
