Installer.OnCommitted(IDictionary) 方法


引發 Committed 事件。Raises the Committed event.

 virtual void OnCommitted(System::Collections::IDictionary ^ savedState);
protected virtual void OnCommitted (System.Collections.IDictionary savedState);
abstract member OnCommitted : System.Collections.IDictionary -> unit
override this.OnCommitted : System.Collections.IDictionary -> unit
Protected Overridable Sub OnCommitted (savedState As IDictionary)



IDictionary,包含 Installers 屬性中的所有安裝程式執行後的電腦狀態。An IDictionary that contains the state of the computer after all the installers in the Installers property run.


下列範例示範OnCommitted Installer類別的方法。The following example demonstrates the OnCommitted method of the Installer class. OnCommitted方法會在衍生類別中覆寫。The OnCommitted method is overridden in the derived class. 提供空間給使用者, 以新增要在認可之前和認可之後執行的步驟。Space is provided for the user to add the steps to be performed before committing and after committing.

   // Override the 'OnCommitted' method.
   virtual void OnCommitted( IDictionary^ savedState ) override
      Installer::OnCommitted( savedState );
      // Add steps to be done after committing an application.
      Console::WriteLine( "The OnCommitted method of MyInstaller called" );
// Override the 'OnCommitted' method.
protected override void OnCommitted(IDictionary savedState)
   // Add steps to be done after committing an application.
   Console.WriteLine("The OnCommitted method of MyInstaller called");
' Override the 'OnCommitted' method.
Protected Overrides Sub OnCommitted(savedState As IDictionary)
   ' Add steps to be done after committing an application.
   Console.WriteLine("The OnCommitted method of MyInstaller called")
End Sub


這個方法會在這個實例Commit的安裝程式集合中包含的所有安裝程式的方法執行之後呼叫。This method is called after the Commit methods of all the installers contained in this instance's installer collection 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.

OnCommitted方法可讓衍生類別處理事件, 而不需要附加委派。The OnCommitted 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.


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