C# Blog Reader - 2 - Get data into an app

Dan Fernandez, Golnaz, Jim Walker — Fri, 26 Oct 2012 16:50:21 GMT

In this video we'll build a set of classes to represent a blog post, a blog, and a collection of blogs that download RSS or Atom feeds from the Web using the SyndicationClient class.

Changes in the video as of 3/25/2013

Change URLs to use blogs.windows instead of windowsteamblogs. For feed1, change it to use the new SkyDrive blog in place of the deleted Developers blog.

public async Task GetFeedsAsync()

{

Task feed1 =

GetFeedAsync("http://blogs.windows.com/skydrive/b/skydrive/atom.aspx");

Task feed2 =

GetFeedAsync("http://blogs.windows.com/windows/b/windowsexperience/atom.aspx");

Task feed3 =

GetFeedAsync("http://blogs.windows.com/windows/b/extremewindows/atom.aspx");

Task feed4 =

GetFeedAsync("http://blogs.windows.com/windows/b/business/atom.aspx");

Task feed5 =

GetFeedAsync("http://blogs.windows.com/windows/b/bloggingwindows/atom.aspx");

Task feed6 =

GetFeedAsync("http://blogs.windows.com/windows/b/windowssecurity/atom.aspx");

Task feed7 =

GetFeedAsync("http://blogs.windows.com/windows/b/springboard/atom.aspx");

Task feed8 =

GetFeedAsync("http://blogs.windows.com/windows/b/windowshomeserver/atom.aspx");

// There is no Atom feed for this blog, so use the RSS feed.

Task feed9 =

GetFeedAsync("http://blogs.windows.com/windows_live/b/windowslive/rss.aspx");

Task feed10 =

GetFeedAsync("http://blogs.windows.com/windows_live/b/developer/atom.aspx");

Task feed11 =

GetFeedAsync("http://blogs.windows.com/ie/b/ie/atom.aspx");

Task feed12 =

GetFeedAsync("http://blogs.windows.com/windows_phone/b/wpdev/atom.aspx");

Task feed13 =

GetFeedAsync("http://blogs.windows.com/windows_phone/b/wmdev/atom.aspx");

Task feed14 =

GetFeedAsync("http://blogs.windows.com/windows_phone/b/windowsphone/atom.aspx");

In GetFeedAsync, don't add 'http://windowsteamblog.com' to the item id when processing an Atom feed. They've updated the id format, so we can just use the id now.

if (feed.SourceFormat == SyndicationFormat.Atom10)

{

if (item.Content != null && item.Content.Text != null)

{

feedItem.Content = item.Content.Text;

}

if (item.Id != null)

{

feedItem.Link = new Uri("http://windowsteamblog.com" + item.Id); // just use feedItem.Link = new Uri(item.Id);

Check for null values in GetFeed and GetItem.

var matches = _feedDataSource.Feeds.Where((feed) => feed != null && feed.Title.Equals(title));

var matches = _feedDataSource.Feeds

.Where(group => group != null)

.SelectMany(group => group.Items).Where((item) => item.Title.Equals(uniqueId));
