Remarques

Les propriétés du nouvel MailMessage objet sont initialisées comme suit :

Paramètre	Propriété
from	From
to	To
subject	Subject
body	Body

Par défaut, l’objet et le contenu sont supposés utiliser l’encodage par défaut en fonction des paramètres de l’ordinateur local. Utilisez les BodyEncoding propriétés et SubjectEncoding pour spécifier différents encodages.
