下列程式碼範例將示範如何使用這個成員。The following code example demonstrates the use of this member. 在此範例中,事件處理常式會報告事件的發生情況 AppearanceChangedIn the example, an event handler reports on the occurrence of the AppearanceChanged event. 這份報告可協助您瞭解發生事件的時間,並協助您進行調試。This report helps you to learn when the event occurs and can assist you in debugging. 若要報告多個事件或經常發生的事件,請考慮將取代為 MessageBox.Show Console.WriteLine 或將訊息附加至多行 TextBoxTo 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.

若要執行範例程式碼,請將它貼到包含名為之類型實例的專案中 RadioButton RadioButton1To run the example code, paste it into a project that contains an instance of type RadioButton named RadioButton1. 然後確定事件處理常式與事件相關聯 AppearanceChangedThen ensure that the event handler is associated with the AppearanceChanged event.

private void RadioButton1_AppearanceChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the RadioButton.AppearanceChanged event.");
Private Sub RadioButton1_AppearanceChanged(sender as Object, e as EventArgs) _ 
     Handles RadioButton1.AppearanceChanged

   MessageBox.Show("You are in the RadioButton.AppearanceChanged event.")

End Sub
