IDictionary，其中這個方法儲存執行認可、復原或解除安裝作業所需的資訊。
例外狀況
savedState 參數為 null。
安裝失敗，正在進行復原。
範例
下列範例示範 TransactedInstaller類別的 TransactedInstaller 、 Install 和 Uninstall 方法。
此範例提供與 InstallUtil.exe 類似的實作。 它會使用該特定元件前面的選項來安裝元件。 如果未為元件指定選項，如果清單中有先前的元件，則會採用先前的元件選項。 如果指定 『/u』 或 『/uninstall』 選項，則會卸載元件。 如果 '/？' 或 '/help' 選項會提供，然後會將說明資訊列印到控制台。

備註
這個方法會 Install 呼叫這個實例的 屬性中包含的 Installers 每個安裝程式方法。 IDictionary參數所savedState參考的物件會更新，以反映安裝在自主安裝程式執行之後的狀態。 如果所有 Install 方法都成功，則會 Commit 呼叫 方法。 否則， Rollback 會針對每個安裝程式呼叫 方法。
給呼叫者的注意事項
IDictionary傳遞至 Install(IDictionary) 方法時，savedState參數所指定的 應該為空白。
