La Namespace proprietà consente di impostare un nome univoco per l'attributo XML. La Namespace proprietà è conforme alle regole per la creazione di uno spazio dei nomi XML disponibile nel documento XML del World Wide Web Consortium.
Per impostare la Namespace proprietà su un nome preceduto, creare un oggetto XmlSerializerNamespaces contenente gli spazi dei nomi e i prefissi usati nel documento XML. Impostare la Namespace proprietà su uno degli spazi dei nomi in XmlSerializerNamespaces. Quando viene generato il codice XML, il nome dell'attributo viene preceduto correttamente dal prefisso associato allo spazio dei nomi specificato.
