例

次のコードは、 SyndicationItem 派生クラスを作成し、RSS 2.0 にシリアル化する方法を示しています。

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()

注釈

このクラスを使用して、 SyndicationItem派生クラスのインスタンスをシリアル化し、RSS 2.0 アイテムを表す XML ドキュメントから SyndicationFeed派生クラスのインスタンスを作成します。 SyndicationItem インスタンスをシリアル化する必要がある場合は、Rss20ItemFormatter フォーマッタを使用します。
