示例

下面的代码示例演示如何使用此成员。The following code example demonstrates the use of this member. 在此示例中,事件处理程序报告事件的发生 StyleChangedIn the example, an event handler reports on the occurrence of the StyleChanged event. 此报表可帮助你了解何时发生事件,并可帮助你进行调试。This report helps you to learn when the event occurs and can assist you in debugging. 若要报告多个事件或频繁发生的事件,请考虑 MessageBox.Show Console.WriteLine 将消息替换为多行或将其追加到多行 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.

若要运行示例代码,请将其粘贴到一个项目中,该项目包含从继承的类型的实例 Control ,如 ButtonComboBoxTo run the example code, paste it into a project that contains an instance of a type that inherits from Control, such as a Button or ComboBox. 然后命名该实例 Control1 ,并确保事件处理程序与事件相关联 StyleChangedThen name the instance Control1 and ensure that the event handler is associated with the StyleChanged event.

private void Control1_StyleChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the Control.StyleChanged event.");
}
Private Sub Control1_StyleChanged(sender as Object, e as EventArgs) _ 
     Handles Control1.StyleChanged

   MessageBox.Show("You are in the Control.StyleChanged event.")

End Sub
