Exemples

L’exemple suivant illustre les TransactedInstallerméthodes et Install Uninstall de la TransactedInstaller classe .

Cet exemple fournit une implémentation similaire à celle de Installutil.exe (outil d’installation). Il installe les 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 utilisées 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 s’affichent sur la console.

Remarques

Appelez cette méthode pour supprimer une installation précédemment terminée. Cette Uninstall méthode appelle la Uninstall méthode de chaque programme d’installation de la Installers propriété pour désinstaller toutes les ressources définies pendant l’installation. Toutes les exceptions pendant la désinstallation sont ignorées.

Notes

Bien que les Install méthodes et Commit enregistrent l’état de l’ordinateur après les installations, le fichier contenant le IDictionarysavedState du paramètre a peut-être été supprimé à un moment donné une fois l’installation terminée. Si le fichier est supprimé, le savedState paramètre est null.
