FeedReader .NET Library

FeedReader is a .NET library for reading and parsing RSS and ATOM feeds. It supports RSS 0.91, 0.92, 1.0, 2.0, and ATOM formats. You can install it as a NuGet package.

https://www.nuget.org/packages/CodeHollow.FeedReader/

Use FeedReader.ReadAsync(url) to asynchronously fetch and parse a feed. The returned object provides common properties like Title, Description, ImageUrl, and a collection of Items.

var feed = await FeedReader.ReadAsync("https://arminreiter.com/feed");

Console.WriteLine("Feed Title: " + feed.Title);
Console.WriteLine("Feed Description: " + feed.Description);
Console.WriteLine("Feed Image: " + feed.ImageUrl);
// ...
foreach(var item in feed.Items)
{
    Console.WriteLine(item.Title + " - " + item.Link);
}

If you only have a website URL and not the direct feed URL, use FeedReader.GetFeedUrlsFromUrl(url) to parse the HTML page and find available feed links.

string url = "arminreiter.com";
var urls = FeedReader.GetFeedUrlsFromUrl(url);
            
string feedUrl;
if (urls.Count() < 1) // no url - probably the url is already the right feed url
    feedUrl = url;
else if (urls.Count() == 1)
    feedUrl = urls.First().Url;
else if (urls.Count() == 2) // if 2 urls, then its usually a feed and a comments feed, so take the first per default
    feedUrl = urls.First().Url;
else
{
    // show all urls and let the user select (or take the first or ...)
    // ...
}

var readerTask = FeedReader.ReadAsync(feedUrl);
readerTask.ConfigureAwait(false);

foreach (var item in readerTask.Result.Items)
{
    Console.WriteLine(item.Title + " - " + item.Link);
    // ...
}

Some properties are specific to certain feed versions (e.g., RSS 2.0). To access these, check the Type property and cast the SpecificFeed property to the appropriate type, such as Feeds.Rss20Feed.

var feed = await FeedReader.ReadAsync("https://arminreiter.com/feed");

Console.WriteLine("Feed Title: " + feed.Title);
            
if(feed.Type == FeedType.Rss_2_0)
{
    var rss20feed = (Feeds.Rss20Feed)feed.SpecificFeed;
    Console.WriteLine("Generator: " + rss20feed.Generator);
}
