次の例ではToolBar 、とToolBarButton 3 つのコントロールをインスタンス化します。The following example instantiates a ToolBar and three ToolBarButton controls. ツールバーのボタンはボタンコレクションに割り当てられ、コレクションはツールバーに割り当てられ、ツールバーはフォームに追加されます。The toolbar buttons are assigned to the button collection, the collection is assigned to the toolbar, and the toolbar is added to the form. ツールバー ToolBarButtonClickEventArgsのイベントでは、のButtonプロパティが評価され、適切なダイアログがButtonClick開きます。On the ButtonClick event of the toolbar, the Button property of the ToolBarButtonClickEventArgs is evaluated, and the appropriate dialog opened. FormこのコードではOpenFileDialog SaveFileDialog、、、、、およびPrintDialogがインスタンス化されていることを前提としています。This code assumes that a Form, an OpenFileDialog, a SaveFileDialog, and a PrintDialog have been instantiated.

注釈

ToolBarButtonClickEventHandler デリゲートを作成する場合は、イベントを処理するメソッドを指定します。When you create a ToolBarButtonClickEventHandler delegate, you identify the method that will handle the event. イベントをイベント ハンドラーに関連付けるには、デリゲートのインスタンスをイベントに追加します。To associate the event with your event handler, add an instance of the delegate to the event. デリゲートを削除しない限り、そのイベントが発生すると常にイベント ハンドラーが呼び出されます。The event handler is called whenever the event occurs, unless you remove the delegate. デリゲートを使用したイベントの処理の詳細については、「イベントの処理と発生」を参照してください。For more information about handling events with delegates, see Handling and Raising Events.
