Sumber:

XmlDocumentFragment.cs

Membuat duplikat simpul ini.

public:
 override System::Xml::XmlNode ^ CloneNode(bool deep);

public override System.Xml.XmlNode CloneNode(bool deep);

override this.CloneNode : bool -> System.Xml.XmlNode

Public Overrides Function CloneNode (deep As Boolean) As XmlNode

Parameter

deep

Boolean

true untuk mengkloning subtree secara rekursif di bawah simpul yang ditentukan; false untuk mengkloning hanya simpul itu sendiri.

Mengembalikan

XmlNode

Simpul kloning.

Contoh

Contoh berikut menunjukkan perbedaan antara klon yang dalam dan dangkal.

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

Keterangan

CloneNode berfungsi sebagai konstruktor salinan untuk simpul. Untuk melihat perilaku metode ini dengan jenis node lain, lihat XmlNode.CloneNode.

Simpul kloning tidak memiliki induk (ParentNode mengembalikan null).
