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}");
}
