Best Way to read rss feed in .net Using C#

Question

What is the best way to read RSS feeds?

I am using XmlTextReader to achieve this. Is there any other best way to do it?

XmlText         


        

Answer 1

Update: This supports only with UWP - Windows Community Toolkit

There is a much easier way now. You can use the RssParser class. The sample code is given below.

public async void ParseRSS()
{
    string feed = null;

    using (var client = new HttpClient())
    {
        try
        {
            feed = await client.GetStringAsync("https://visualstudiomagazine.com/rss-feeds/news.aspx");
        }
        catch { }
    }

    if (feed != null)
    {
        var parser = new RssParser();
        var rss = parser.Parse(feed);

        foreach (var element in rss)
        {
            Console.WriteLine($"Title: {element.Title}");
            Console.WriteLine($"Summary: {element.Summary}");
        }
    }
}

For non-UWP use the Syndication from the namespace System.ServiceModel.Syndication as others suggested.

public static IEnumerable <FeedItem> GetLatestFivePosts() {
    var reader = XmlReader.Create("https://sibeeshpassion.com/feed/");
    var feed = SyndicationFeed.Load(reader);
    reader.Close();
    return (from itm in feed.Items select new FeedItem {
        Title = itm.Title.Text, Link = itm.Id
    }).ToList().Take(5);
}

public class FeedItem {
    public string Title {
        get;
        set;
    }
    public string Link {
        get;
        set;
    }
}

This is an old post, but to save people some time if you get here now like I did, I suggest you have a look at the CodeHollow.FeedReader package which supports a wider range of RSS versions, is easier to use and seems more robust. https://github.com/codehollow/FeedReader

Answer 3

Use this :

private string GetAlbumRSS(SyndicationItem album)
    {

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

    }
    protected void Page_Load(object sender, EventArgs e)
    {
        string albumRSS;
        string url = "http://www.SomeSite.com/rss‎";
        XmlReader r = XmlReader.Create(url);
        SyndicationFeed albums = SyndicationFeed.Load(r);
        r.Close();
        foreach (SyndicationItem album in albums.Items)
        {

            cell.InnerHtml = cell.InnerHtml +string.Format("<br \'><a href='{0}'>{1}</a>", album.Links[0].Uri, album.Title.Text);
            albumRSS = GetAlbumRSS(album);

        }



    }

Answer 4

Add System.ServiceModel in references

Using SyndicationFeed:

string url = "http://fooblog.com/feed";
XmlReader reader = XmlReader.Create(url);
SyndicationFeed feed = SyndicationFeed.Load(reader);
reader.Close();
foreach (SyndicationItem item in feed.Items)
{
    String subject = item.Title.Text;    
    String summary = item.Summary.Text;
    ...                
}

Answer 5

You're looking for the SyndicationFeed class, which does exactly that.
