 event EventHandler ^ FormatInfoChanged;
public event EventHandler FormatInfoChanged;
member this.FormatInfoChanged : EventHandler 
Public Custom Event FormatInfoChanged As EventHandler 


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 FormatInfoChanged 事件的发生。In the example, an event handler reports on the occurrence of the FormatInfoChanged 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 ListControl的类型的实例,如 ComboBoxListBoxTo run the example code, paste it into a project that contains an instance of a type that inherits from ListControl, such as a ComboBox or ListBox. 然后,将该实例命名为 ListControl1 并确保事件处理程序与 FormatInfoChanged 事件关联。Then name the instance ListControl1 and ensure that the event handler is associated with the FormatInfoChanged event.

private void ListControl1_FormatInfoChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the ListControl.FormatInfoChanged event.");
Private Sub ListControl1_FormatInfoChanged(sender as Object, e as EventArgs) _ 
     Handles ListControl1.FormatInfoChanged

   MessageBox.Show("You are in the ListControl.FormatInfoChanged event.")

End Sub
