InstallerCollection

Esempio

Nell'esempio seguente viene illustrato il Add metodo della InstallerCollection classe . In questo esempio viene fornita un'implementazione simile a quella di Installutil.exe (strumento di installazione). Installa gli assembly con le opzioni precedenti a quel particolare assembly. Se non viene specificata un'opzione per un assembly, le opzioni dell'assembly precedente vengono prese se è presente un assembly precedente nell'elenco. Se viene specificata l'opzione "/u" o "/uninstall", gli assembly vengono disinstallati. Se viene fornita l'opzione "/?" o "/help", le informazioni della Guida vengono visualizzate nella console.

Commenti

fornisce InstallerCollection i metodi e le proprietà necessari all'applicazione per gestire una raccolta di Installer oggetti.

Usare uno dei tre modi seguenti per aggiungere programmi di installazione alla raccolta:

• Il Add metodo aggiunge un singolo programma di installazione alla raccolta.

• I AddRange metodi aggiungono più programmi di installazione alla raccolta.

• Il Insert metodo e la Item[] proprietà , ovvero l'indicizzatore InstallerCollection , aggiungono un singolo programma di installazione alla raccolta in corrispondenza dell'indice specificato.

Rimuovere i programmi di installazione tramite il Remove metodo . Controllare se un programma di installazione si trova nella raccolta usando il Contains metodo . Individuare dove si trova un programma di installazione nella raccolta usando il IndexOf metodo .

I programmi di installazione in una raccolta vengono eseguiti quando il programma di installazione contenente la raccolta, come specificato dalla Installer.Parent proprietà , chiama i Installrelativi metodi , CommitRollback, o Uninstall .

Per esempi di utilizzo di una raccolta di programmi di installazione, vedere le AssemblyInstaller classi e TransactedInstaller .
