Esempio

Il codice seguente illustra come creare una SyndicationItem classe derivata e serializzarla in 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()

Commenti

Utilizzare questa classe per serializzare istanze di SyndicationItemclassi derivate da e per creare istanze di SyndicationFeedclassi derivate da documenti XML che rappresentano elementi RSS 2.0. Se è necessario serializzare un'istanza SyndicationItem di , usare il formattatore Rss20ItemFormatter .
