XNode.WriteTo(XmlWriter) 方法

定义

命名空间:

System.Xml.Linq

程序集:

System.Xml.XDocument.dll

程序集:

System.Xml.Linq.dll

程序集:

netstandard.dll

将此节点写入 XmlWriter。

public:
 abstract void WriteTo(System::Xml::XmlWriter ^ writer);

public abstract void WriteTo (System.Xml.XmlWriter writer);

abstract member WriteTo : System.Xml.XmlWriter -> unit

Public MustOverride Sub WriteTo (writer As XmlWriter)

参数

writer

XmlWriter

此方法将写入其中的 XmlWriter。

示例

以下示例创建一个 XmlWriter 写入到 a StringBuilder. 然后，此方法使用此方法将两个 XML 树写入编写器。

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())  

该示例产生下面的输出：

<Root>  
  <Child>  
    <GrandChild>some content</GrandChild>  
  </Child>  
  <AnotherChild>  
    <GrandChild>different content</GrandChild>  
  </AnotherChild>  
</Root>
