XmlDocumentFragment.CloneNode(Boolean) Metod

Definition

Skapar en dubblett av den här noden.

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

Parametrar

deep
Boolean

true för att rekursivt klona underträdet under den angivna noden. false för att endast klona själva noden.

Returer

Den klonade noden.

Exempel

I följande exempel visas skillnaden mellan en djup och ytlig klon.

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

Kommentarer

CloneNode fungerar som en kopieringskonstruktor för noder. Information om hur den här metoden fungerar med andra nodtyper finns i XmlNode.CloneNode.

Den klonade noden har ingen överordnad (ParentNode returnerar null).
