savedState
IDictionary

IDictionary,包含 Installers 屬性中包含的安裝程式都復原之後的電腦狀態。An IDictionary that contains the state of the computer after the installers contained in the Installers property are rolled back.

備註

這個方法會在這個Rollback InstallerCollection實例中所有安裝程式的方法都執行之後呼叫。This method is called after the Rollback methods of all the installers in this instance's InstallerCollection have run.

引發事件會透過委派叫用此事件處理常式。Raising an event invokes the event handler through a delegate. 如需詳細資訊, 請參閱處理和引發事件For more information, see Handling and Raising Events.

OnAfterRollback方法可讓衍生類別處理事件, 而不需要附加委派。The OnAfterRollback method allows derived classes to handle the event without attaching a delegate. 這是在衍生類別中處理事件的慣用技巧。This is the preferred technique for handling the event in a derived class.

給繼承者的注意事項

當在衍生類別中覆寫 OnAfterRollback(IDictionary) 時,請確定呼叫基底類別的 OnAfterRollback(IDictionary) 方法,使已註冊的委派能接收到事件。When overriding OnAfterRollback(IDictionary) in a derived class, be sure to call the base class's OnAfterRollback(IDictionary) method so that registered delegates receive the event.
