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>" & _

    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.Prepend(newAttr)

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

  end sub
end class

注釈

同じ名前の属性がコレクション内に既に存在する場合は、元の属性がコレクションから削除され、node がコレクションの先頭に追加されます。If an attribute with the same name is already present in the collection, the original attribute is removed from the collection and node is added to the beginning of the collection.
