 Rss20ItemFormatter();

public Rss20ItemFormatter ();

Public Sub New ()

Rss20ItemFormatter(SyndicationItem)

创建 Rss20ItemFormatter 类的新实例。

public:

public Rss20ItemFormatter (System.ServiceModel.Syndication.SyndicationItem itemToWrite);

new System.ServiceModel.Syndication.Rss20ItemFormatter : System.ServiceModel.Syndication.SyndicationItem -> System.ServiceModel.Syndication.Rss20ItemFormatter

Public Sub New (itemToWrite As SyndicationItem)

参数

itemToWrite

SyndicationItem

要序列化的 SyndicationItem。

示例

下面的示例演示如何调用此构造函数。

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 = new SyndicationFeed();
item.Summary = new TextSyndicationContent("This the item summary");

XmlWriter rssWriter = XmlWriter.Create("RssItem.xml");
Rss20ItemFormatter formatter = new Rss20ItemFormatter(item);

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 = New SyndicationFeed()
item.Summary = New TextSyndicationContent("This the item summary")

Dim rssWriter As XmlWriter = XmlWriter.Create("RssItem.xml")
Dim formatter As Rss20ItemFormatter = New Rss20ItemFormatter(item)

Rss20ItemFormatter(Type)

创建 Rss20ItemFormatter 类的新实例。

public:
 Rss20ItemFormatter(Type ^ itemTypeToCreate);

public Rss20ItemFormatter (Type itemTypeToCreate);

new System.ServiceModel.Syndication.Rss20ItemFormatter : Type -> System.ServiceModel.Syndication.Rss20ItemFormatter

Public Sub New (itemTypeToCreate As Type)

参数

itemTypeToCreate

Type

要与 SyndicationItem 关联的派生自 Rss20ItemFormatter 的实例。

示例

下面的代码演示如何使用此构造函数。

Rss20ItemFormatter myItemRssFormatter = new Rss20ItemFormatter(typeof(MySyndicationItem));
XmlReader rssReader = XmlReader.Create("http://Contoso/Feeds/MyFeed/Items");
myItemRssFormatter.ReadFrom(rssReader);
rssReader.Close();

注解

使用此构造函数可以指定要在读入联合项时实例化的 SyndicationItem 派生类。

Rss20ItemFormatter(SyndicationItem, Boolean)

创建 Rss20ItemFormatter 类的新实例。

public:
 Rss20ItemFormatter(System::ServiceModel::Syndication::SyndicationItem ^ itemToWrite, bool serializeExtensionsAsAtom);

public Rss20ItemFormatter (System.ServiceModel.Syndication.SyndicationItem itemToWrite, bool serializeExtensionsAsAtom);

new System.ServiceModel.Syndication.Rss20ItemFormatter : System.ServiceModel.Syndication.SyndicationItem * bool -> System.ServiceModel.Syndication.Rss20ItemFormatter

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

参数

itemToWrite

SyndicationItem

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。

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 = new SyndicationFeed();
item.Summary = new TextSyndicationContent("This the item summary");

XmlWriter rssWriter = XmlWriter.Create("RssItem.xml");
Rss20ItemFormatter formatter = new Rss20ItemFormatter(item, true);

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 = New SyndicationFeed()
item.Summary = New TextSyndicationContent("This the item summary")

Dim rssWriter As XmlWriter = XmlWriter.Create("RssItem.xml")
Dim formatter As Rss20ItemFormatter = New Rss20ItemFormatter(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。
