Atom10ItemFormatter 類別

定義

此類別可將 SyndicationItem 執行個體序列化為 Atom 1.0 格式,或自 Atom 1.0 序列化為原來的執行個體。A class that serializes a SyndicationItem instance to and from Atom 1.0 format.

public ref class Atom10ItemFormatter : System::ServiceModel::Syndication::SyndicationItemFormatter, System::Xml::Serialization::IXmlSerializable
public class Atom10ItemFormatter : System.ServiceModel.Syndication.SyndicationItemFormatter, System.Xml.Serialization.IXmlSerializable
type Atom10ItemFormatter = class
    inherit SyndicationItemFormatter
    interface IXmlSerializable
Public Class Atom10ItemFormatter

範例

下列程式碼會示範如何建立 SyndicationItem 執行個體並將其序列化。The following code shows how to create a SyndicationItem instance and serialize it.

SyndicationItem item = new SyndicationItem("Test Item", "This is the content for Test Item", new Uri("http://localhost/ItemOne"), "TestItemID", DateTime.Now);

item.Links.Add(new SyndicationLink(new Uri("http://someuri"), "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 atomWriter = XmlWriter.Create("AtomItem.xml");
Atom10ItemFormatter formatter = new Atom10ItemFormatter(item);
formatter.WriteTo(atomWriter);
atomWriter.Close();

Dim item As SyndicationItem = New SyndicationItem("Test Item", "This is the content for Test Item", New Uri("http:'localhost/ItemOne"), "TestItemID", DateTime.Now)

item.Links.Add(New SyndicationLink(New Uri("http:'someuri"), "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 atomWriter As XmlWriter = XmlWriter.Create("AtomItem.xml")
Dim formatter As Atom10ItemFormatter = New Atom10ItemFormatter(item)
formatter.WriteTo(atomWriter)
atomWriter.Close()

備註

您可以使用此類別序列化 SyndicationItem 的執行個體,並且從包含 Atom 1.0 項目的 XML 文件,建立 SyndicationItem 的執行個體。Use this class to serialize instances of SyndicationItem and to create an instance of SyndicationItem from an XML document that contains an Atom 1.0 entry. 若您自 SyndicationItem 衍生類別並且想要將它序列化,請改而使用 Atom10ItemFormatter<TSyndicationItem> 格式器。If you have derived a class from SyndicationItem and want to serialize it, use the Atom10ItemFormatter<TSyndicationItem> formatter instead.

注意

Atom 1.0 規格允許在其任何日期建構中指定小數秒數。The Atom 1.0 specification allows for fractional seconds to be specified in any of its date constructs. 當序列化和還原序列化時,WCF 執行會忽略小數秒數。When serializing and deserializing, the WCF implementation ignores the fractional seconds.
