   //Create a new attribute.
   XmlAttribute^ newAttr = doc->CreateAttribute( "genre" );
   newAttr->Value = "novel";
   
   //Create an attribute collection and add the new attribute
   //to the collection.
   XmlAttributeCollection^ attrColl = doc->DocumentElement->Attributes;
   attrColl->InsertAfter( newAttr, attrColl[ 0 ] );
   Console::WriteLine( "Display the modified XML...\r\n" );
   Console::WriteLine( doc->OuterXml );
}

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

public class Sample
{
  public static void Main(){

    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<book ISBN='1-861001-57-5'>" +
                "<title>Pride And Prejudice</title>" +
                "</book>");

    //Create a new attribute.
    XmlAttribute newAttr = doc.CreateAttribute("genre");
    newAttr.Value = "novel";

    //Create an attribute collection and add the new attribute
    //to the collection.
    XmlAttributeCollection attrColl = doc.DocumentElement.Attributes;
    attrColl.InsertAfter(newAttr, attrColl[0]);

    Console.WriteLine("Display the modified XML...\r\n");
    Console.WriteLine(doc.OuterXml);
  }
}

Imports System.IO
Imports System.Xml

public class Sample

  public shared sub Main()
  
    Dim doc as XmlDocument = new XmlDocument()
    doc.LoadXml("<book ISBN='1-861001-57-5'>" & _
                "<title>Pride And Prejudice</title>" & _
                "</book>")      

    'Create a new attribute.
    Dim newAttr as XmlAttribute = doc.CreateAttribute("genre")
    newAttr.Value = "novel"

    'Create an attribute collection and add the new attribute
    'to the collection.  
    Dim attrColl as XmlAttributeCollection = doc.DocumentElement.Attributes
    attrColl.InsertAfter(newAttr, attrColl.ItemOf(0))

    Console.WriteLine("Display the modified XML...")
    Console.WriteLine(doc.OuterXml)

  end sub
end class

Remarks

If an attribute with the same name is already present in the collection, the original attribute is removed from the collection and newNode is inserted into the collection. If refNode is null, newNode is inserted at the beginning of the collection.
