- savedState
- IDictionary
Metoda IDictionary , ve které tato metoda ukládá informace potřebné k provedení potvrzení, vrácení zpět nebo odinstalace operace.
Výjimky
Parametr savedState je null.
Instalace se nezdařila a vrací se zpět.
Příklady
Následující příklad ukazuje TransactedInstaller, Install a Uninstall metody TransactedInstaller třídy.
Tento příklad poskytuje implementaci podobnou InstallUtil.exe. Nainstaluje sestavení s možnostmi předcházejícími danému konkrétnímu sestavení. Pokud není pro sestavení zadána možnost, předchozí možnosti sestavení se pořídí, pokud je v seznamu předchozí sestavení. Pokud je zadána možnost /u nebo /uninstall, jsou sestavení odinstalována. Pokud je hodnota /? nebo možnost /help je k dispozici, pak se informace nápovědy vytisknou do konzoly.

Poznámky
Tato metoda volá metodu Install každého instalačního programu obsaženého ve Installers vlastnosti této instance. Objekt IDictionary odkazovaný parametrem savedState se aktualizuje tak, aby odrážel stav instalace po spuštění obsažených instalačních programů. Pokud jsou všechny Install metody úspěšné, volá se Commit metoda. Jinak se Rollback metoda volá pro každý instalační program.
Poznámky pro volající
savedState Zadaný IDictionary parametr by měl být při předání Install(IDictionary) metodě prázdný.
