Using SyndicationFeed to display photos from spaces.live.com

  • Artikel

The SyndicationFeed class from System.ServiceModel.Syndicatation makes it easy to work with feeds and extensions. The code below uses an RSS feed from space.live.com to show photo albums on a page. Of course there are many ways to consume RSS with and w/o code, but the WCF enhancements with .NET 3.5 are a nice new trick. You can see the result at https://www.steveres.com/SpacesPics.aspx

r = XmlReader.Create("https://yournamegoeshere.spaces.live.com/photos/feed.rss");
albums = SyndicationFeed.Load(r);
r.Close();
foreach (SyndicationItem album in albums.Items)
{

// album.links[0].URI points to this album page on spaces.live.com
// album.Summary (not shown) is an HTML block with thumbnails of the album pics
cell.Text= string.Format("<a href='{0}'>{1}</a>", album.Links[0].Uri, album.Title.Text);
albumRSS = GetAlbumRSS(album);
r = XmlReader.Create(albumRSS);
photos = SyndicationFeed.Load(r);
r.Close();
foreach (SyndicationItem photo in photos.Items)
{
// photo.Summary is an HTML block with a thumbnail of the pic
      cell.Text = string.Format("{0}", photo.Summary.Text);
}

}
//
// helper to extract the feed to one album from the albums feed
//
private string GetAlbumRSS(SyndicationItem album)
{

string url = "";
foreach (SyndicationElementExtension ext in album.ElementExtensions)
       if (ext.OuterName == "itemRSS") url = ext.GetObject<string>();
return (url);

}

    Hi Steve, I want to validate RSS feed url given by the user programmatically. Ofcourse, there are lot of web sites they do validate rss feeds...like http://validator.w3.org/feed/check.cgi?url="RSS Feed uRL"...it will validate and tell you the results. But i want to do programmatically using .NET ...so is there any API is available....it would be great if you help in this regard. Thanks & Regards, Kathir

    Ashokraj we use webclient to solve this issue. using (WebClient client = new WebClient())            {                //set your proxy to client here                string data = client.DownloadString(url);                using (XmlReader reader = XmlReader.Create(new StringReader(data)))                {                    SyndicationFeed feed = SyndicationFeed.Load(reader);                    foreach (SyndicationItem item in feed.Items)                    {                        String subject = item.Title.Text;                        Console.WriteLine("{0}" , subject);                    }                }            }
