Ruft den Knoten am angegebenen Index in der XmlNamedNodeMap ab.

public:
 virtual System::Xml::XmlNode ^ Item(int index);

public virtual System.Xml.XmlNode Item (int index);

public virtual System.Xml.XmlNode? Item (int index);

abstract member Item : int -> System.Xml.XmlNode
override this.Item : int -> System.Xml.XmlNode

Public Overridable Function Item (index As Integer) As XmlNode

Parameter

index

Int32

Die Indexposition des aus der XmlNamedNodeMap abzurufenden Knotens. Der Index ist nullbasiert. Daher ist der Index des ersten Knotens 0 und der des letzten Knotens Count -1.

Gibt zurück

XmlNode

Das XmlNode-Objekt am angegebenen Index. Wenn index kleiner als 0 oder größer oder gleich der Count-Eigenschaft ist, wird null zurückgegeben.

Beispiele

Im folgenden Beispiel wird die XmlAttributeCollection Klasse (die erbt von XmlNamedNodeMap) verwendet, um alle Attribute eines Buchs anzuzeigen.

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
{
   XmlDocument^ doc = gcnew XmlDocument;
   doc->LoadXml( "<book genre='novel' publicationdate='1997'>   <title>Pride And Prejudice</title></book>" );
   XmlAttributeCollection^ attrColl = doc->DocumentElement->Attributes;
   Console::WriteLine( "Display all the attributes for this book..." );
   for ( int i = 0; i < attrColl->Count; i++ )
   {
      Console::WriteLine( "{0} = {1}", attrColl->Item( i )->Name, attrColl->Item( i )->Value );

   }
}

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

public class Sample
{
  public static void Main()
  {
     XmlDocument doc = new XmlDocument();
     doc.LoadXml("<book genre='novel' publicationdate='1997'> " +
                 "  <title>Pride And Prejudice</title>" +
                 "</book>");

     XmlAttributeCollection attrColl = doc.DocumentElement.Attributes;

     Console.WriteLine("Display all the attributes for this book...");
     for (int i=0; i < attrColl.Count; i++)
     {
        Console.WriteLine("{0} = {1}", attrColl.Item(i).Name, attrColl.Item(i).Value);
     }
  }
}
