Przykłady

W poniższym przykładzie przedstawiono TransactedInstallerInstall metody TransactedInstaller i klasy .Uninstall

W tym przykładzie przedstawiono implementację podobną do implementacjiInstallutil.exe (narzędzie instalatora). Instaluje zestawy z opcjami poprzedzającymi ten konkretny zestaw. Jeśli dla zestawu nie określono opcji, opcje poprzedniego zestawu są używane, jeśli na liście znajduje się poprzedni zestaw. Jeśli zostanie określona opcja "/u" lub "/uninstall", zestawy zostaną odinstalowane. Jeśli zostanie podana opcja "/?" lub "/help", informacje pomocy zostaną wyświetlone w konsoli programu .

Uwagi

Wywołaj tę metodę, aby usunąć poprzednio ukończoną instalację. Ta Uninstall metoda wywołuje metodę Uninstall każdego instalatora we właściwości, Installers aby odinstalować wszystkie zasoby ustawione podczas instalacji. Wszelkie wyjątki podczas odinstalowywania są ignorowane.

Uwaga

Install Mimo że metody i Commit zapisują stan komputera po instalacji, plik zawierający IDictionary parametr savedState mógł zostać usunięty w pewnym momencie po zakończeniu instalacji. Jeśli plik zostanie usunięty, savedState parametr to null.
