There are several ways to load and manipulate a feed.

• Load – takes 3 overloads taking either a System.Uri, a String containg the feed's XML, or an XmlReader. You can provide RSS/Atom/RDF or OPML formatted feeds for any of these 3 overloads and it will automatically identify the base feed type and construct the class appropriately.
• SelectItems – returns an IEnumerable which can be gives the ability to iterate over the collection. It is also used internally to provide data binding capability to RssDataSource.
• ToXml – returns a String with the Xml of the feed in any supported format for publishing the feed . The input parameter {(enum DocumentType}} specifies the format of Xml returned as RSS/Atom/RDF or OPML.
• ToDataSet – returns the feed contents as a DataSet. This is useful to directly assign to a data-bound control.

An example of using RssDocument directly to bind to a GridView:

void Page_Load(object sender, EventArgs e)
{
    RssToolkit.Rss.RssDocument rss = RssToolkit.Rss.RssDocument.Load(new System.Uri("http://rss.msnbc.msn.com/id/3032091/device/rss/rss.xml"));
    Image1.ImageUrl = rss.Channel.Image.Url;
    GridView1.DataSource = rss.SelectItems();
    GridView1.DataBind();
}
