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 AutoSizeChanged 事件的发生。In the example, an event handler reports on the occurrence of the AutoSizeChanged 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,请考虑将 MessageBox.Show 替换为 Console.WriteLine 或将消息附加到多行 TextBox中。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.

若要运行示例代码,请将其粘贴到一个项目中,该项目包含继承自 UpDownBase的类型的实例,如 NumericUpDownDomainUpDownTo run the example code, paste it into a project that contains an instance of a type that inherits from UpDownBase, such as a NumericUpDown or DomainUpDown. 然后,将该实例命名为 UpDownBase1 并确保事件处理程序与 AutoSizeChanged 事件关联。Then name the instance UpDownBase1 and ensure that the event handler is associated with the AutoSizeChanged event.

private void UpDownBase1_AutoSizeChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the UpDownBase.AutoSizeChanged event.");
}
Private Sub UpDownBase1_AutoSizeChanged(sender as Object, e as EventArgs) _ 
     Handles UpDownBase1.AutoSizeChanged

   MessageBox.Show("You are in the UpDownBase.AutoSizeChanged event.")

End Sub
