Commenti

Utilizzare questo costruttore per specificare una classe derivata da SyndicationFeed per creare un'istanza durante la lettura di un feed di diffusione.

public:
 Rss20FeedFormatter(System::ServiceModel::Syndication::SyndicationFeed ^ feedToWrite, bool serializeExtensionsAsAtom);

public Rss20FeedFormatter (System.ServiceModel.Syndication.SyndicationFeed feedToWrite, bool serializeExtensionsAsAtom);

new System.ServiceModel.Syndication.Rss20FeedFormatter : System.ServiceModel.Syndication.SyndicationFeed * bool -> System.ServiceModel.Syndication.Rss20FeedFormatter

Public Sub New (feedToWrite As SyndicationFeed, serializeExtensionsAsAtom As Boolean)
