XmlDocumentFragment.CloneNode(Boolean) 方法
定义
重要
一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。 对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。
创建此节点的副本。
public:
override System::Xml::XmlNode ^ CloneNode(bool deep);public override System.Xml.XmlNode CloneNode(bool deep);override this.CloneNode : bool -> System.Xml.XmlNodePublic Overrides Function CloneNode (deep As Boolean) As XmlNode参数
- deep
- Boolean
若要递归地克隆指定节点下的子树，则为 true；若仅克隆节点本身，则为 false。
返回
克隆的节点。
示例
以下示例演示深层克隆和浅表克隆之间的差异。
using System;
using System.IO;
using System.Xml;
public class Sample
{
public static void Main()
{
// Create the XmlDocument.
XmlDocument doc = new XmlDocument();
doc.LoadXml("<items/>");
// Create a document fragment.
XmlDocumentFragment docFrag = doc.CreateDocumentFragment();
// Set the contents of the document fragment.
docFrag.InnerXml ="<item>widget</item>";
// Create a deep clone. The cloned node
// includes child nodes.
XmlNode deep = docFrag.CloneNode(true);
Console.WriteLine("Name: " + deep.Name);
Console.WriteLine("OuterXml: " + deep.OuterXml);
// Create a shallow clone. The cloned node does
// not include any child nodes.
XmlNode shallow = docFrag.CloneNode(false);
Console.WriteLine("Name: " + shallow.Name);
Console.WriteLine("OuterXml: " + shallow.OuterXml);
}
}
Imports System.IO
Imports System.Xml
public class Sample
public shared sub Main()
' Create the XmlDocument.
Dim doc as XmlDocument = new XmlDocument()
doc.LoadXml("<items/>")
' Create a document fragment.
Dim docFrag as XmlDocumentFragment = doc.CreateDocumentFragment()
' Set the contents of the document fragment.
docFrag.InnerXml ="<item>widget</item>"
' Create a deep clone. The cloned node
' includes child nodes.
Dim deep as XmlNode = docFrag.CloneNode(true)
Console.WriteLine("Name: " + deep.Name)
Console.WriteLine("OuterXml: " + deep.OuterXml)
' Create a shallow clone. The cloned node does
' not include any child nodes.
Dim shallow as XmlNode = docFrag.CloneNode(false)
Console.WriteLine("Name: " + shallow.Name)
Console.WriteLine("OuterXml: " + shallow.OuterXml)
end sub
end class
注解
CloneNode 用作节点的复制构造函数。 若要查看此方法与其他节点类型的行为方式，请参阅 XmlNode.CloneNode。
克隆的节点没有父 (ParentNode 返回 null) 。
