Atom10ItemFormatter<TSyndicationItem> Class

A class that serializes SyndicationItem-derived classes to and from Atom 1.0 format.

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

public class Atom10ItemFormatter<TSyndicationItem> : Atom10ItemFormatter 
where TSyndicationItem : new(), SyndicationItem

Type Parameters


The SyndicationItem -derived class to serialize.

Use this class to serialize instances of SyndicationItem-derived classes and to create instances of SyndicationFeed-derived classes from XML documents that contain Atom1.0 entries. If you must serialize a SyndicationItem instance use the Atom10ItemFormatter formatter instead.


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 demonstrates how to create a SyndicationItem-derived class and serialize it to Atom 1.0.

MySyndicationItem item = new MySyndicationItem("Test Item", "This is the content for Test Item", new Uri("http://localhost/ItemOne"), "TestItemID", DateTime.Now);

item.Links.Add(new SyndicationLink(new Uri("http://someuri"), "alternate", "MyItemLink", "text/html", 100));
item.PublishDate = new DateTime(1968, 2, 23);
item.LastUpdatedTime = DateTime.Today;
item.SourceFeed = new SyndicationFeed();
item.Summary = new TextSyndicationContent("This the item summary");

XmlWriter atomWriter = XmlWriter.Create("AtomItem.xml");
Atom10ItemFormatter<MySyndicationItem> formatter = new Atom10ItemFormatter<MySyndicationItem>(item);

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