Remarques
Dans l’exemple suivant d’en-tête Content-Type, la valeur de la Name propriété est "data.xyz"
.
content-type: application/x-myType; name=data.xyz
Une grammaire qui détaille la syntaxe de l’en-tête Content-Type est décrite dans RFC 2045 Section 5.1, disponible à l’adresse https://www.ietf.org.
Lorsque vous spécifiez le contenu d’un AttachmentStream en tant que ou String, vous pouvez utiliser Name pour définir le nom du fichier qui stocke le contenu sur le système du destinataire.
