 event System::Windows::Forms::HtmlElementEventHandler ^ Unload;
public event System.Windows.Forms.HtmlElementEventHandler Unload;
member this.Unload : System.Windows.Forms.HtmlElementEventHandler 
Public Custom Event Unload As HtmlElementEventHandler 

次のコード例では、このメンバーの使用を示します。The following code example demonstrates the use of this member. 例では、イベント ハンドラーが発生するときに報告、Unloadイベント。In the example, an event handler reports on the occurrence of the Unload event. このレポートでは、イベントが発生してデバッグに役立つについて説明します。This report helps you to learn when the event occurs and can assist you in debugging. 複数のイベントまたは頻繁に発生するイベントを報告する、交換を検討MessageBox.ShowConsole.WriteLineまたはメッセージを複数行に追加TextBoxします。To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

コード例を実行する型のインスタンスを含むプロジェクトに貼り付けることHtmlWindowというHtmlWindow1します。To run the example code, paste it into a project that contains an instance of type HtmlWindow named HtmlWindow1. イベント ハンドラーに関連付けられていることを確認し、Unloadイベント。Then ensure that the event handler is associated with the Unload event.
