首先从controlInstance.Click事件开始. 用Reflector反编译System.Windows.Forms.Control类可以看到对Click事件的定义:
[System.Windows.Forms.SRCategory("CatAction"), System.Windows.Forms.SRDescription("ControlOnClickDescr")] 
public event EventHandler Click 
{ 
add 
{ 
base.Events.AddHandler(Control.EventClick, value); 
} 
remove
本文关键：.net WinForm 控件的事件委托剖析
