Rss20FeedFormatter rssFormatter = new Rss20FeedFormatter();
rssFormatter.ReadFrom(rssReader);
rssReader.Close();

Dim rssReader As XmlReader = XmlReader.Create("http://contoso/Feeds/RSS/MyFeed")
Dim rssFormatter As New Rss20FeedFormatter()
rssFormatter.ReadFrom(rssReader)
rssReader.Close()

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

public Rss20FeedFormatter (System.ServiceModel.Syndication.SyndicationFeed feedToWrite);

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

Public Sub New (feedToWrite As SyndicationFeed)

Parâmetros

feedToWrite

SyndicationFeed

O SyndicationFeed a ser serializado.

Exemplos

O exemplo a seguir mostra como chamar esse construtor.

    SyndicationFeed feed = new SyndicationFeed("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://Contoso/ItemOne"), "TestItemID", DateTime.Now);

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

    XmlWriter rssWriter = XmlWriter.Create("RSS.xml");
    Rss20FeedFormatter rssFormatter = new Rss20FeedFormatter(feed);

Dim feed As SyndicationFeed = New SyndicationFeed("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://Contoso/ItemOne"), "TestItemID", DateTime.Now)

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

Dim rssWriter As XmlWriter = XmlWriter.Create("RSS.xml")
Dim rssFormatter As Rss20FeedFormatter = New Rss20FeedFormatter(feed)

Rss20FeedFormatter(Type)

Cria uma nova instância da classe Rss20FeedFormatter.

public:
 Rss20FeedFormatter(Type ^ feedTypeToCreate);

public Rss20FeedFormatter (Type feedTypeToCreate);

new System.ServiceModel.Syndication.Rss20FeedFormatter : Type -> System.ServiceModel.Syndication.Rss20FeedFormatter

Public Sub New (feedTypeToCreate As Type)

Parâmetros

feedTypeToCreate

Type

A instância derivada de SyndicationFeed a ser serializada.

Exemplos

O código a seguir mostra como usar esse construtor.

Rss20FeedFormatter myFeedRssFormatter = new Rss20FeedFormatter(typeof(MySyndicationFeed));
XmlReader rssReader = XmlReader.Create("http://Contoso/Feeds/MyFeed");
myFeedRssFormatter.ReadFrom(rssReader);
rssReader.Close();

Dim myFeedRssFormatter As New Rss20FeedFormatter(GetType(MySyndicationFeed))
Dim rssReader As XmlReader = XmlReader.Create("http://Contoso/Feeds/MyFeed")
myFeedRssFormatter.ReadFrom(rssReader)
rssReader.Close()

Comentários

Use esse construtor para especificar uma classe derivada de SyndicationFeed para instanciar quando um feed de sindicalização é lido.

Rss20FeedFormatter(SyndicationFeed, Boolean)

Cria uma nova instância da classe Rss20FeedFormatter com a instância SyndicationFeed especificada.

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)

Parâmetros

feedToWrite

SyndicationFeed

O SyndicationFeed a ser serializado.

serializeExtensionsAsAtom

Boolean

Um valor que especifica se elementos que são definidos na especificação do Atom 1.0, mas não na especificação do RSS 2.0, devem ou não ser serializados. O valor padrão é true.

Exemplos

O exemplo a seguir mostra como chamar esse construtor.

    SyndicationFeed feed = new SyndicationFeed("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://Contoso/ItemOne"), "TestItemID", DateTime.Now);

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

    XmlWriter rssWriter = XmlWriter.Create("RSS.xml");
    Rss20FeedFormatter rssFormatter = new Rss20FeedFormatter(feed, true);

Dim feed As SyndicationFeed = New SyndicationFeed("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://Contoso/ItemOne"), "TestItemID", DateTime.Now)

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

Dim rssWriter As XmlWriter = XmlWriter.Create("RSS.xml")
Dim rssFormatter As Rss20FeedFormatter = New Rss20FeedFormatter(feed, True)

Comentários

Se o serializeExtensionsAsAtom parâmetro for true, todos os elementos definidos na especificação Atom 1.0 que não estão definidos na especificação RSS 2.0 serão serializados no namespace Atom 1.0.
