Ejemplos

En el código siguiente se muestra cómo crear una SyndicationItem clase derivada y serializarla en RSS 2.0.

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

item.Links.Add(new SyndicationLink(new Uri("http://Contoso"), "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 rssWriter = XmlWriter.Create("RssItem.xml");
Rss20ItemFormatter<MySyndicationItem> formatter = new Rss20ItemFormatter<MySyndicationItem>(item);
formatter.WriteTo(rssWriter);
rssWriter.Close();

Dim item As MySyndicationItem = New MySyndicationItem("Test Item", "This is the content for Test Item", New Uri("http://Contoso/ItemOne"), "TestItemID", DateTime.Now)

item.Links.Add(New SyndicationLink(New Uri("http://Contoso"), "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")

Dim rssWriter As XmlWriter = XmlWriter.Create("RssItem.xml")
Dim formatter As Rss20ItemFormatter(Of MySyndicationItem) = New Rss20ItemFormatter(Of MySyndicationItem)(item)
formatter.WriteTo(rssWriter)
rssWriter.Close()

Comentarios

Use esta clase para serializar instancias de clases derivadas de SyndicationItemy para crear instancias de clases derivadas de SyndicationFeeddocumentos XML que representan elementos RSS 2.0. Si necesita serializar una SyndicationItem instancia, use el Rss20ItemFormatter formateador.
