Commenti

Utilizzare la AttributeName proprietà per specificare un nome di attributo XML quando non è possibile utilizzare il valore predefinito. Ad esempio, se il nome dell'attributo XML non è valido come identificatore di membro, è possibile usare un nome valido per l'identificatore impostando su AttributeName un nome non valido.
