XmlNode.GetEnumerator Metod

public:
 System::Collections::IEnumerator ^ GetEnumerator();

public System.Collections.IEnumerator GetEnumerator();

member this.GetEnumerator : unit -> System.Collections.IEnumerator

Public Function GetEnumerator () As IEnumerator

Returer

Ett IEnumerator objekt som kan användas för att iterera via de underordnade noderna i den aktuella noden.

Exempel

I följande exempel visas alla böcker i XML-dokumentet.

using System;
using System.Collections;
using System.Xml;

public class Sample {

  public static void Main() {

    XmlDocument doc = new XmlDocument();
    doc.Load("books.xml");

    Console.WriteLine("Display all the books...");
    XmlNode root = doc.DocumentElement;
    IEnumerator ienum = root.GetEnumerator();
    XmlNode book;
    while (ienum.MoveNext())
    {
      book = (XmlNode) ienum.Current;
      Console.WriteLine(book.OuterXml);
      Console.WriteLine();
    }
  }
}

Imports System.Collections
Imports System.Xml

public class Sample

  public shared sub Main()
  
    Dim doc as XmlDocument = new XmlDocument()
    doc.Load("books.xml")

    Console.WriteLine("Display all the books...")
    Dim root as XmlNode = doc.DocumentElement
    Dim ienum as IEnumerator = root.GetEnumerator()
    Dim book as XmlNode
    while (ienum.MoveNext())      
      book = CType(ienum.Current, XmlNode)
      Console.WriteLine(book.OuterXml)
      Console.WriteLine()
    end while

  end sub
end class

I exemplet används filen , books.xmlsom indata.

<?xml version='1.0'?>

Kommentarer

Ger stöd för iterationen "för varje" format över noderna i XmlNode.

Den här metoden är ett Microsoft-tillägg till dokumentobjektmodellen (DOM).
