XmlNode.Clone XmlNode.Clone XmlNode.Clone XmlNode.Clone Method

定義

建立這個節點的複本。Creates a duplicate of this node.

public:
 virtual System::Xml::XmlNode ^ Clone();
public virtual System.Xml.XmlNode Clone ();
abstract member Clone : unit -> System.Xml.XmlNode
override this.Clone : unit -> System.Xml.XmlNode
Public Overridable Function Clone () As XmlNode

傳回

複製的節點。The cloned node.

範例

下列範例會複製 XML 檔的根節點。The following example clones the root node of the XML document.

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
{
   XmlDocument^ doc = gcnew XmlDocument;
   doc->LoadXml( "<book ISBN='1-861001-57-5'>"
   "<title>Pride And Prejudice</title>"
   "<price>19.95</price>"
   "</book>" );
   XmlNode^ root = doc->FirstChild;
   
   //Clone the root node.  The cloned node includes
   //child nodes. This is similar to calling CloneNode(true).
   XmlNode^ clone = root->Clone();
   Console::WriteLine( clone->OuterXml );
}

using System;
using System.IO;
using System.Xml;

public class Sample {

  public static void Main() {

    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<book ISBN='1-861001-57-5'>" +
                "<title>Pride And Prejudice</title>" +
                "<price>19.95</price>" +
                "</book>");

    XmlNode root = doc.FirstChild;

    //Clone the root node.  The cloned node includes
    //child nodes. This is similar to calling CloneNode(true).
    XmlNode clone = root.Clone();
    Console.WriteLine(clone.OuterXml);
  }
}
Option Explicit
Option Strict

Imports System.IO
Imports System.Xml

Public Class Sample
    Public Shared Sub Main()
        
        Dim doc As New XmlDocument()
        doc.LoadXml("<book ISBN='1-861001-57-5'>" & _
                    "<title>Pride And Prejudice</title>" & _
                    "<price>19.95</price>" & _
                    "</book>")
        
        Dim root As XmlNode = doc.FirstChild
        
        'Clone the root node.  The cloned node includes
        'child nodes. This is similar to calling CloneNode(true).
        Dim clone As XmlNode = root.Clone()
        Console.WriteLine(clone.OuterXml)
    End Sub

備註

XmlElement複製所有屬性及其值,包括由 XML 處理器產生以代表預設屬性的屬性。Cloning an XmlElement copies all attributes and their values, including those generated by the XML processor to represent defaulted attributes. 這個方法會以遞迴方式複製節點及其底下的子樹。This method recursively clones the node and the subtree underneath it.

Clone相當於呼叫CloneNode(true)Clone is equivalent to calling CloneNode(true).

下表描述每個XmlNodeType的特定行為。The following table describes the specific behavior for each XmlNodeType.
