示例
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.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 = feed;
item.Summary = new TextSyndicationContent("This the item summary");
List<SyndicationItem> items = new List<SyndicationItem>();
items.Add(item);
feed.Items = items;
XmlWriter rssWriter = XmlWriter.Create("Rss.xml");
Rss20FeedFormatter<MySyndicationFeed> rssFormatter = new Rss20FeedFormatter<MySyndicationFeed>(feed);
Dim feed As MySyndicationFeed = New MySyndicationFeed("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)
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 = 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)
适用于
Rss20FeedFormatter<TSyndicationFeed>(TSyndicationFeed, Boolean)
使用指定的 Rss20FeedFormatter<TSyndicationFeed> 派生实例创建 SyndicationFeed 类的新实例。
public:
Rss20FeedFormatter(TSyndicationFeed feedToWrite, bool serializeExtensionsAsAtom);public Rss20FeedFormatter (TSyndicationFeed feedToWrite, bool serializeExtensionsAsAtom);new System.ServiceModel.Syndication.Rss20FeedFormatter<'SyndicationFeed (requires 'SyndicationFeed :> System.ServiceModel.Syndication.SyndicationFeed and 'SyndicationFeed : (new : unit -> 'SyndicationFeed))> : 'SyndicationFeed * bool -> System.ServiceModel.Syndication.Rss20FeedFormatter<'SyndicationFeed (requires 'SyndicationFeed :> System.ServiceModel.Syndication.SyndicationFeed and 'SyndicationFeed : (new : unit -> 'SyndicationFeed))>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。
示例
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.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 = feed;
item.Summary = new TextSyndicationContent("This the item summary");
List<SyndicationItem> items = new List<SyndicationItem>();
items.Add(item);
feed.Items = items;
XmlWriter rssWriter = XmlWriter.Create("Rss.xml");
Rss20FeedFormatter<MySyndicationFeed> rssFormatter = new Rss20FeedFormatter<MySyndicationFeed>(feed, true);
Dim feed As MySyndicationFeed = New MySyndicationFeed("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)
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 = 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。
