Exemplos

O código a seguir mostra como criar uma SyndicationFeed classe derivada e serializá-la para Atom 1,0.The following code shows how to create a SyndicationFeed-derived class and serialize it to Atom 1.0.

MySyndicationFeed feed = new MySyndicationFeed("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);

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 = feed;
item.Summary = new TextSyndicationContent("This the item summary");

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

XmlWriter atomWriter = XmlWriter.Create("Atom.xml");
Atom10FeedFormatter<MySyndicationFeed> atomFormatter = new Atom10FeedFormatter<MySyndicationFeed>(feed);
atomFormatter.WriteTo(atomWriter);
atomWriter.Close();
Dim feed As MySyndicationFeed = New MySyndicationFeed("Test Feed", "This is a test feed", New Uri("http:'Contoso/testfeed"), "TestFeedID", DateTime.Now)
Dim item As SyndicationItem = New SyndicationItem("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 = feed
item.Summary = New TextSyndicationContent("This the item summary")

Dim items As List(Of SyndicationItem) = New List(Of SyndicationItem)
items.Add(item)
feed.Items = items

Dim atomWriter As XmlWriter = XmlWriter.Create("Atom.xml")
Dim atomFormatter As Atom10FeedFormatter(Of MySyndicationFeed) = New Atom10FeedFormatter(Of MySyndicationFeed)(feed)
atomFormatter.WriteTo(atomWriter)
atomWriter.Close()

Comentários

Use essa classe para serializar instâncias de SyndicationFeed classes derivadas e para criar instâncias de SyndicationFeed classes derivadas de documentos XML que contêm feeds Atom 1,0.Use this class to serialize instances of SyndicationFeed-derived classes and to create instances of SyndicationFeed derived classes from XML documents that contain Atom 1.0 feeds. Se você precisar serializar uma SyndicationFeed instância, use o Atom10FeedFormatter formatador em vez disso.If you must serialize a SyndicationFeed instance, use the Atom10FeedFormatter formatter instead.

Observação

A especificação Atom 1,0 permite que os segundos fracionários sejam especificados em qualquer uma de suas construções de data.The Atom 1.0 specification allows for fractional seconds to be specified in any of its date constructs. Ao serializar e desserializar, a implementação do WCF ignora os segundos fracionários.When serializing and deserializing, the WCF implementation ignores the fractional seconds.
