About

Provides types for generating and consuming RSS and Atom feeds. It is used for creating and parsing syndication feeds, making it easier to build and integrate web content syndication.

Key Features

• Easy generation and parsing of RSS and Atom feeds.
• Customizable for different syndication needs.
• Support for both feed reading and writing.

How to Use

Creating a Feed

using System.ServiceModel.Syndication;
using System.Xml;

// Create a new syndication feed
SyndicationFeed feed = new SyndicationFeed(
 "Feed Title",
 "Feed Description",
 new Uri("http://example.com"),
 "FeedID",
 DateTime.Now);

// Add items to the feed
SyndicationItem item1 = new SyndicationItem(
 "Title1",
 "Content1",
 new Uri("http://example.com/item1"));
feed.Items = new List<SyndicationItem> { item1 };

// Serialize the feed to RSS format
using (XmlWriter writer = XmlWriter.Create("rss.xml"))
{
 Rss20FeedFormatter rssFormatter = new Rss20FeedFormatter(feed);
 rssFormatter.WriteTo(writer);
}

Resulting RSS feed:

<?xml version="1.0" encoding="utf-8"?>
<rss xmlns:a10="http://www.w3.org/2005/Atom" version="2.0">
 <channel>
 <title>Feed Title</title>
 <link>http://example.com/</link>
 <description>Feed Description</description>
 <lastBuildDate>Sat, 11 Nov 2023 18:05:21 +0100</lastBuildDate>
 <a10:id>FeedID</a10:id>
 <item>
 <link>http://example.com/item1</link>
 <title>Title1</title>
 <description>Content1</description>
 </item>
 </channel>
</rss>

Consuming a Feed

using System.ServiceModel.Syndication;
using System.Xml;

string feedUrl = "https://devblogs.microsoft.com/dotnet/feed/";
using XmlReader reader = XmlReader.Create(feedUrl);

// Read the feed using Atom10FeedFormatter.
SyndicationFeed feed = SyndicationFeed.Load(reader);

Console.WriteLine($"Feed Title: {feed.Title.Text}");
Console.WriteLine("Feed Items:");

// Iterate through the feed items and display the title and a brief summary of each.
foreach (SyndicationItem item in feed.Items)
{
 Console.WriteLine($"Title: {item.Title.Text}");
 Console.WriteLine($"Published Date: {item.PublishDate.DateTime}");
}
