Atom10FeedFormatter Class

A class that serializes a SyndicationFeed instance to and from Atom 1.0 format.

Namespace:  System.ServiceModel.Syndication
Assembly:  System.ServiceModel.Web (in System.ServiceModel.Web.dll)

public class Atom10FeedFormatter : SyndicationFeedFormatter, 

Use this class to serialize instances of SyndicationFeed and to create instances of SyndicationFeed from XML documents that represent Atom1.0 feeds. If you have derived a class from SyndicationFeed and want to serialize it, use the Atom10FeedFormatter<TSyndicationFeed> formatter.


The Atom 1.0 specification allows for fractional seconds to be specified in any of its date constructs. When serializing and deserializing, the WCF implementation ignores the fractional seconds.

The following code shows how to create a SyndicationFeed and serialize it to Atom 1.0.

SyndicationFeed feed = new SyndicationFeed("Test Feed", "This is a test feed", new Uri("http://Contoso/testfeed"), "TestFeedID", DateTime.Now);
SyndicationItem item = new SyndicationItem("Test Item", "This is the content for Test Item", new Uri("http://localhost/ItemOne"), "TestItemID", DateTime.Now);

List<SyndicationItem> items = new List<SyndicationItem>();
feed.Items = items;

XmlWriter atomWriter = XmlWriter.Create("Atom.xml");
Atom10FeedFormatter atomFormatter = new Atom10FeedFormatter(feed);

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
