Exemples

L’exemple suivant illustre la Add méthode de la InstallerCollection classe . Cet exemple fournit une implémentation similaire à celle de Installutil.exe (outil d’installation). Il installe des assemblys avec les options qui précèdent cet assembly particulier. Si aucune option n’est spécifiée pour un assembly, les options de l’assembly précédent sont prises s’il existe un assembly précédent dans la liste. Si l’option « /u » ou « /uninstall » est spécifiée, les assemblys sont désinstallés. Si l’option « / ? » ou « /help » est fournie, les informations d’aide sont affichées dans la console.

Remarques

Fournit InstallerCollection les méthodes et les propriétés dont votre application a besoin pour gérer une collection d’objets Installer .

Utilisez l’une des trois méthodes suivantes pour ajouter des programmes d’installation à la collection :

• La Add méthode ajoute un programme d’installation unique à la collection.

• Les AddRange méthodes ajoutent plusieurs programmes d’installation à la collection.

• La Insert méthode et la Item[] propriété, qui est l’indexeur InstallerCollection , ajoutent chacun un programme d’installation unique à la collection à l’index spécifié.

Supprimez les programmes d’installation à l’aide de la Remove méthode . Vérifiez si un programme d’installation se trouve dans la collection à l’aide de la Contains méthode . Recherchez l’emplacement d’un programme d’installation dans la collection à l’aide de la IndexOf méthode .

Les programmes d’installation d’une collection sont exécutés lorsque le programme d’installation contenant la collection, comme spécifié par la Installer.Parent propriété , appelle leurs Installméthodes , Commit, Rollbackou Uninstall .

Pour obtenir des exemples d’utilisation d’une collection de programmes d’installation, consultez les AssemblyInstaller classes et TransactedInstaller .
