XNode.WriteTo(XmlWriter) 方法
重要
部分資訊涉及發行前產品,在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊,不做任何明確或隱含的瑕疵擔保。
將這個節點寫入 XmlWriter。
public:
abstract void WriteTo(System::Xml::XmlWriter ^ writer);
C#
public abstract void WriteTo(System.Xml.XmlWriter writer);
abstract member WriteTo : System.Xml.XmlWriter -> unit
Public MustOverride Sub WriteTo (writer As XmlWriter)
下列範例會 XmlWriter 建立寫入 的 StringBuilder 。 然後,它會使用這個方法,將兩個 XML 樹狀架構寫入寫入器。
C#
StringBuilder sb = new StringBuilder();
XmlWriterSettings xws = new XmlWriterSettings();
xws.OmitXmlDeclaration = true;
xws.Indent = true;
using (XmlWriter xw = XmlWriter.Create(sb, xws)) {
xw.WriteStartElement("Root");
XElement child1 = new XElement("Child",
new XElement("GrandChild", "some content")
);
child1.WriteTo(xw);
XElement child2 = new XElement("AnotherChild",
new XElement("GrandChild", "different content")
);
child2.WriteTo(xw);
xw.WriteEndElement();
}
Console.WriteLine(sb.ToString());
Dim sb As StringBuilder = New StringBuilder()
Dim xws As XmlWriterSettings = New XmlWriterSettings()
xws.OmitXmlDeclaration = True
xws.Indent = True
Using xw = XmlWriter.Create(sb, xws)
xw.WriteStartElement("Root")
Dim child1 As XElement = <Child>
<GrandChild>some content</GrandChild>
</Child>
child1.WriteTo(xw)
Dim child2 As XElement = <AnotherChild>
<GrandChild>different content</GrandChild>
</AnotherChild>
child2.WriteTo(xw)
xw.WriteEndElement()
End Using
Console.WriteLine(sb.ToString())
這個範例會產生下列輸出:
XML
<Root>
<Child>
<GrandChild>some content</GrandChild>
</Child>
<AnotherChild>
<GrandChild>different content</GrandChild>
</AnotherChild>
</Root>
您可以使用這個方法來撰寫程式碼,以執行非常大型檔的串流轉換。 如需詳細資訊,請參閱 如何執行大型 XML 檔的串流轉換。
