推荐答案

这取决于您要实现的目标.如果您有多个事件处理程序必须在表单/对象的生命周期内处理各种控件的事件，那么 WithEvents 和 Handles 是最简单的方法.在设置活动方面，该语言将为您完成所有繁琐的工作.另一方面，如果您倾向于在表单的生命周期内断开与事件的连接，那么 AddHandler 和 RemoveHandler 是更好的选择.

It depends on what you're trying to achieve. If you have several event handlers which must handle events for various controls during the lifetime of a form/object then WithEvents and Handles is the easiest way to go. The language will do all of the dirty work for you in terms of setting up the event. On the other hand, if you tend to disconnect from events during the lifetime of the form, AddHandler and RemoveHandler are better options.
