.NET Framework Class Library MailMessageEventHandler Delegate Represents the method that handles mail events. (in System.Web.dll)
Syntax
Public Delegate Sub MailMessageEventHandler ( _
sender As Object, _
e As MailMessageEventArgs _
)
public delegate void MailMessageEventHandler(
Object sender,
MailMessageEventArgs e
)
public delegate void MailMessageEventHandler(
Object^ sender,
MailMessageEventArgs^ e
)
type MailMessageEventHandler =
delegate of
sender:Object *
e:MailMessageEventArgs -> unit
Remarks
The MailMessageEventHandler delegate modifies the contents of an Internet e-mail message before the message is sent to the recipients. For example, you can add additional recipients or a custom message footer identifying your Web site to all messages using this handler. The e parameter is a MailMessageEventArgs instance that contains the e-mail message specified in the Message property. When you create a MailMessageEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see Events and Delegates.
Examples
The following code example creates a MailMessageEventHandler instance to modify an e-mail message before sending it to the recipient.

Bibliothèque de classes .NET Framework MailMessageEventHandler, délégué Représente la méthode qui gère des événements de messagerie. (dans System.Web.dll)
Syntaxe
Public Delegate Sub MailMessageEventHandler ( _
sender As Object, _
e As MailMessageEventArgs _
)
public delegate void MailMessageEventHandler(
Object sender,
MailMessageEventArgs e
)
public delegate void MailMessageEventHandler(
Object^ sender,
MailMessageEventArgs^ e
)
type MailMessageEventHandler =
delegate of
sender:Object *
e:MailMessageEventArgs -> unit
Notes
Le délégué MailMessageEventHandler modifie le contenu d'un message électronique Internet avant que le message soit envoyé aux destinataires. Par exemple, vous pouvez ajouter des destinataires supplémentaires ou un pied de page de message personnalisé qui identifie votre site Web à tous les messages à l'aide de ce gestionnaire. Le paramètre e est une instance de MailMessageEventArgs qui contient le message électronique spécifié dans la propriété Message. Lorsque vous créez un délégué MailMessageEventHandler, vous identifiez la méthode qui gérera l'événement. Pour associer l'événement à votre gestionnaire d'événements, ajoutez une instance du délégué à l'événement. Le gestionnaire d'événements est appelé à chaque fois que l'événement se produit, sauf si vous supprimez le délégué. Pour plus d'informations sur les délégués de gestionnaires d'événements, consultez Événements et délégués.

L'exemple de code suivant crée une instance de MailMessageEventHandler pour modifier un message électronique avant de l'envoyer au destinataire.
