XmlNode.GetEnumerator 方法

定義

命名空間:

System.Xml

組件:

System.Xml.ReaderWriter.dll

來源:

XmlNode.cs

取得逐一查看目前節點中子節點的列舉程式。

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

public System.Collections.IEnumerator GetEnumerator ();

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

Public Function GetEnumerator () As IEnumerator

傳回

IEnumerator

IEnumerator 物件，可用來逐一查看目前節點中的子節點。

範例

下列範例會顯示 XML 檔中的所有書籍。

#using <System.Xml.dll>

using namespace System;
using namespace System::Collections;
using namespace System::Xml;
int main()
{
   XmlDocument^ doc = gcnew 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 = dynamic_cast<XmlNode^>(ienum->Current);
      Console::WriteLine( book->OuterXml );
      Console::WriteLine();
   }
}

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

此範例會使用 檔案 books.xml ，作為輸入。

<?xml version='1.0'?>
<!-- This file represents a fragment of a book store inventory database -->
