Exempel

I följande exempel visas Add metoden för InstallerCollection klassen. Det här exemplet innehåller en implementering som liknar den förInstallutil.exe (installationsverktyg). Den installerar sammansättningar med de alternativ som föregår den specifika sammansättningen. Om ett alternativ inte har angetts för en sammansättning används alternativen för den tidigare sammansättningen om det finns en tidigare sammansättning i listan. Om alternativet "/u" eller "/uninstall" anges avinstalleras sammansättningarna. Om alternativet "/?" eller "/help" tillhandahålls visas hjälpinformationen för konsolen.

Kommentarer

InstallerCollection Innehåller de metoder och egenskaper som programmet behöver för att hantera en samling Installer objekt.

Använd något av följande tre sätt att lägga till installationsprogram i samlingen:

• Metoden Add lägger till ett enda installationsprogram i samlingen.

• Metoderna AddRange lägger till flera installationsprogram i samlingen.

• Metoden Insert och Item[] egenskapen, som är InstallerCollection indexeraren, lägger var och en till ett enda installationsprogram i samlingen vid det angivna indexet.

Ta bort installationsprogram via Remove -metoden. Kontrollera om ett installationsprogram finns i samlingen med hjälp Contains av metoden . Ta reda på var ett installationsprogram finns i samlingen med hjälp IndexOf av metoden .

Installationsprogrammet i en samling körs när installationsprogrammet som innehåller samlingen, enligt vad som anges av Installer.Parent egenskapen, anropar deras Installmetoder , Commit, Rollbackeller Uninstall .

Exempel på användning av en installationssamling finns i klasserna AssemblyInstaller och TransactedInstaller .
