Rss20FeedFormatter()

建立 Rss20FeedFormatter 類別的新執行個體。

public:
 Rss20FeedFormatter();

public Rss20FeedFormatter ();

Public Sub New ()

範例

下列程式碼會示範如何建立 Rss20FeedFormatter 執行個體，並讀入 RSS 新聞訂閱摘要。

XmlReader rssReader = XmlReader.Create("http://contoso/Feeds/RSS/MyFeed");
Rss20FeedFormatter rssFormatter = new Rss20FeedFormatter();
rssFormatter.ReadFrom(rssReader);
rssReader.Close();

Dim rssReader As XmlReader = XmlReader.Create("http://contoso/Feeds/RSS/MyFeed")
Dim rssFormatter As New Rss20FeedFormatter()
rssFormatter.ReadFrom(rssReader)
rssReader.Close()

Rss20FeedFormatter(SyndicationFeed)

以指定的 Rss20FeedFormatter 執行個體建立 SyndicationFeed 類別的新執行個體。

public:
 Rss20FeedFormatter(System::ServiceModel::Syndication::SyndicationFeed ^ feedToWrite);

public Rss20FeedFormatter (System.ServiceModel.Syndication.SyndicationFeed feedToWrite);

new System.ServiceModel.Syndication.Rss20FeedFormatter : System.ServiceModel.Syndication.SyndicationFeed -> System.ServiceModel.Syndication.Rss20FeedFormatter

Public Sub New (feedToWrite As SyndicationFeed)

參數

feedToWrite

SyndicationFeed

要序列化的 SyndicationFeed。

範例

下列範例將示範如何呼叫這個建構函式。

    SyndicationFeed feed = new SyndicationFeed("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);

List<SyndicationItem> items = new List<SyndicationItem>();
items.Add(item);
    feed.Items = items;

    XmlWriter rssWriter = XmlWriter.Create("RSS.xml");
    Rss20FeedFormatter rssFormatter = new Rss20FeedFormatter(feed);

Dim feed As SyndicationFeed = New SyndicationFeed("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)

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 = New Rss20FeedFormatter(feed)

Rss20FeedFormatter(Type)

建立 Rss20FeedFormatter 類別的新執行個體。

public:
 Rss20FeedFormatter(Type ^ feedTypeToCreate);

public Rss20FeedFormatter (Type feedTypeToCreate);

new System.ServiceModel.Syndication.Rss20FeedFormatter : Type -> System.ServiceModel.Syndication.Rss20FeedFormatter

Public Sub New (feedTypeToCreate As Type)

參數

feedTypeToCreate

Type

要序列化的 SyndicationFeed 衍生執行個體。

範例

下列程式碼示範如何使用這個建構函式。

Rss20FeedFormatter myFeedRssFormatter = new Rss20FeedFormatter(typeof(MySyndicationFeed));
XmlReader rssReader = XmlReader.Create("http://Contoso/Feeds/MyFeed");
myFeedRssFormatter.ReadFrom(rssReader);
rssReader.Close();

Dim myFeedRssFormatter As New Rss20FeedFormatter(GetType(MySyndicationFeed))
Dim rssReader As XmlReader = XmlReader.Create("http://Contoso/Feeds/MyFeed")
myFeedRssFormatter.ReadFrom(rssReader)
rssReader.Close()

備註

您可以使用此建構函式，指定讀入新聞訂閱摘時要具現化的 SyndicationFeed 衍生類別。

Rss20FeedFormatter(SyndicationFeed, Boolean)

以指定的 Rss20FeedFormatter 執行個體建立 SyndicationFeed 類別的新執行個體。

public:
 Rss20FeedFormatter(System::ServiceModel::Syndication::SyndicationFeed ^ feedToWrite, bool serializeExtensionsAsAtom);

public Rss20FeedFormatter (System.ServiceModel.Syndication.SyndicationFeed feedToWrite, bool serializeExtensionsAsAtom);

new System.ServiceModel.Syndication.Rss20FeedFormatter : System.ServiceModel.Syndication.SyndicationFeed * bool -> System.ServiceModel.Syndication.Rss20FeedFormatter

Public Sub New (feedToWrite As SyndicationFeed, serializeExtensionsAsAtom As Boolean)

參數

feedToWrite

SyndicationFeed

要序列化的 SyndicationFeed。

serializeExtensionsAsAtom

Boolean

一個值，指定是否要序列化在 Atom 1.0 規格中已定義，但在 RSS 2.0 規格中並未定義的項目。 預設值是 true。

範例

下列範例將示範如何呼叫這個建構函式。

    SyndicationFeed feed = new SyndicationFeed("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);

List<SyndicationItem> items = new List<SyndicationItem>();
items.Add(item);
    feed.Items = items;

    XmlWriter rssWriter = XmlWriter.Create("RSS.xml");
    Rss20FeedFormatter rssFormatter = new Rss20FeedFormatter(feed, true);

Dim feed As SyndicationFeed = New SyndicationFeed("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)

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 = New Rss20FeedFormatter(feed, True)

備註

如果 serializeExtensionsAsAtom 參數為 true，則會使用 Atom 1.0 命名空間序列化在 Atom 1.0 規格中已定義、但是在 RSS 2.0 規格中未定義的所有項目。
