Exemples

L’exemple de code suivant définit la valeur de la propriété pour spécifier un nom pour un fichier attaché en tant que flux.

// and the log as an email attachment.

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.
