Beispiel

Im folgenden Beispiel wird eine Instanz der XmlSerializerNamespaces-Klasse erstellt, und dem Objekt wird ein aus einem Präfix und einem Namespace bestehendes Paar hinzugefügt.

Private Sub CreateBook(filename As String)
   Try
      ' Create instance of XmlSerializerNamespaces and add the namespaces.
      Dim myNameSpaces As New XmlSerializerNamespaces()
      myNameSpaces.Add("BookName", "http://www.cpandl.com")

      ' Create instance of XmlSerializer and specify the type of object;
      ' to be serialized.
      Dim mySerializerObject As New XmlSerializer(GetType(MyBook))
