Dim rssWriter As XmlWriter = XmlWriter.Create("Rss.xml")
Dim rssFormatter As Rss20FeedFormatter(Of MySyndicationFeed) = New Rss20FeedFormatter(Of MySyndicationFeed)(feed)
适用于
Rss20FeedFormatter<TSyndicationFeed>(TSyndicationFeed, Boolean)

Public Sub New (feedToWrite As TSyndicationFeed, serializeExtensionsAsAtom As Boolean)
参数
- feedToWrite
- TSyndicationFeed
要序列化的源。
- serializeExtensionsAsAtom
- Boolean
一个值,指定是否对在 Atom 1.0 规范中已定义但在 RSS 2.0 规范中未定义的元素进行序列化。 默认值为 true
。

下面的示例演示如何调用此构造函数。
MySyndicationFeed feed = new MySyndicationFeed("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);

item.SourceFeed = feed
item.Summary = New TextSyndicationContent("This the item summary")
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(Of MySyndicationFeed) = New Rss20FeedFormatter(Of MySyndicationFeed)(feed, True)
注解
如果 serializeExtensionsAsAtom
参数为 true
,则会用 Atom 1.0 命名空间对在 Atom 1.0 规范中已定义但在 RSS 2.0 规范中未定义的所有元素进行序列化。
