FeedReader is a .net library used for reading and parsing RSS and ATOM feeds. SupportsRSS 0.91, 0.92, 1.0, 2.0 and ATOM.Developed because tested existing libraries do not work with different languages, encodings or have other issues.Library tested with multiple languages, encodings and feeds.
FeedReader library is available as NuGet package:https://www.nuget.org/packages/CodeHollow.FeedReader/
The simplest way to read a feed and show the information is:
varfeed=awaitFeedReader.ReadAsync("https://arminreiter.com/feed");Console.WriteLine("Feed Title: "+feed.Title);Console.WriteLine("Feed Description: "+feed.Description);Console.WriteLine("Feed Image: "+feed.ImageUrl);// ...foreach(variteminfeed.Items){Console.WriteLine(item.Title+" - "+item.Link);}
There are some properties that are only available in e.g. RSS 2.0. If you want to get those properties, the property "SpecificFeed" is the right one:
varfeed=awaitFeedReader.ReadAsync("https://arminreiter.com/feed");Console.WriteLine("Feed Title: "+feed.Title);if(feed.Type==FeedType.Rss_2_0){varrss20feed=(Feeds.Rss20Feed)feed.SpecificFeed;Console.WriteLine("Generator: "+rss20feed.Generator);}
If the url to the feed is not known, then you can use FeedReader.GetFeedUrlsFromUrl(url) to parse the url from the html webpage:
stringurl="arminreiter.com";varurls=FeedReader.GetFeedUrlsFromUrl(url);stringfeedUrl;if(urls.Count()<1)// no url - probably the url is already the right feed urlfeedUrl=url;elseif(urls.Count()==1)feedUrl=urls.First().Url;elseif(urls.Count()==2)// if 2 urls, then its usually a feed and a comments feed, so take the first per defaultfeedUrl=urls.First().Url;else{// show all urls and let the user select (or take the first or ...)// ...}varreaderTask=FeedReader.ReadAsync(feedUrl);readerTask.ConfigureAwait(false);foreach(variteminreaderTask.Result.Items){Console.WriteLine(item.Title+" - "+item.Link);// ...}
The code contains a sample console application:https://github.com/codehollow/FeedReader/tree/master/FeedReader.ConsoleSample
