Hur WCF Syndication Object Model Kartor till Atom och RSS
När du utvecklar en Windows Communication Foundation-syndikeringstjänst (WCF) skapar du feeds och objekt med hjälp av följande klasser:
A SyndicationFeed kan serialiseras till valfritt syndikeringsformat som en formatering har definierats för. WCF levereras med två formaterare: Atom10FeedFormatter och Rss20FeedFormatter.
Objektmodellen runt SyndicationFeed och SyndicationItem justeras närmare med Atom 1.0-specifikationen än RSS 2.0-specifikationen. Det beror på att Atom 1.0 är en mer omfattande specifikation som definierar element som är tvetydiga eller utelämnade från RSS 2.0-specifikationen. Därför har många objekt i WCF-syndikeringsobjektmodellen ingen direkt representation i RSS 2.0-specifikationen. När du serialiserar SyndicationFeed och SyndicationItem objekt i RSS 2.0 kan du med WCF serialisera Atomspecifika dataelement som namnområdeskvalificerade tilläggselement som överensstämmer med Atom-specifikationen. Du kan styra detta med en parameter som skickas Rss20FeedFormatter till konstruktorn.
Kodexemplen i det här avsnittet använder en av två metoder som definierats här för att utföra den faktiska serialiseringen.
SerializeFeed serialiserar ett syndikeringsflöde.
public void SerializeFeed(SyndicationFeed feed)
{
Atom10FeedFormatter atomFormatter = feed.GetAtom10Formatter();
Rss20FeedFormatter rssFormatter = feed.GetRss20Formatter();
XmlWriter atomWriter = XmlWriter.Create("atom.xml");
XmlWriter rssWriter = XmlWriter.Create("rss.xml");
atomFormatter.WriteTo(atomWriter);
rssFormatter.WriteTo(rssWriter);
atomWriter.Close();
rssWriter.Close();
}
Public Sub SerializeFeed(ByVal feed As SyndicationFeed)
Dim atomFormatter As Atom10FeedFormatter = feed.GetAtom10Formatter()
Dim rssFormatter As Rss20FeedFormatter = feed.GetRss20Formatter()
Dim atomWriter As XmlWriter = XmlWriter.Create("atom.xml")
Dim rssWriter As XmlWriter = XmlWriter.Create("rss.xml")
atomFormatter.WriteTo(atomWriter)
rssFormatter.WriteTo(rssWriter)
atomWriter.Close()
rssWriter.Close()
End Sub
SerializeItem serialiserar ett syndikeringsobjekt.
public void SerializeItem(SyndicationItem item)
{
Atom10ItemFormatter atomFormatter = item.GetAtom10Formatter();
Rss20ItemFormatter rssFormatter = item.GetRss20Formatter();
XmlWriter atomWriter = XmlWriter.Create("atom.xml");
XmlWriter rssWriter = XmlWriter.Create("rss.xml");
atomFormatter.WriteTo(atomWriter);
rssFormatter.WriteTo(rssWriter);
atomWriter.Close();
rssWriter.Close();
}
Public Sub SerializeItem(ByVal item As SyndicationItem)
Dim atomFormatter As Atom10ItemFormatter = item.GetAtom10Formatter()
Dim rssFormatter As Rss20ItemFormatter = item.GetRss20Formatter()
Dim atomWriter As XmlWriter = XmlWriter.Create("atom.xml")
Dim rssWriter As XmlWriter = XmlWriter.Create("rss.xml")
atomFormatter.WriteTo(atomWriter)
rssFormatter.WriteTo(rssWriter)
atomWriter.Close()
rssWriter.Close()
End Sub
