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()

public:
 Rss20ItemFormatter(TSyndicationItem itemToWrite, bool serializeExtensionsAsAtom);

public Rss20ItemFormatter (TSyndicationItem itemToWrite, bool serializeExtensionsAsAtom);

new System.ServiceModel.Syndication.Rss20ItemFormatter<'SyndicationItem (requires 'SyndicationItem :> System.ServiceModel.Syndication.SyndicationItem and 'SyndicationItem : (new : unit -> 'SyndicationItem))> : 'SyndicationItem * bool -> System.ServiceModel.Syndication.Rss20ItemFormatter<'SyndicationItem (requires 'SyndicationItem :> System.ServiceModel.Syndication.SyndicationItem and 'SyndicationItem : (new : unit -> 'SyndicationItem))>

Public Sub New (itemToWrite As TSyndicationItem, serializeExtensionsAsAtom As Boolean)

参数

itemToWrite

TSyndicationItem

要序列化的 SyndicationItem。

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。 默认值是 true。

示例

下面的示例演示如何调用此构造函数。

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, true);

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, 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。
