//有重复的事件就清除                    var EventList = GetObjectEventList(item, "EventClick");                    if (EventList != null)                    {                        foreach (Delegate del in EventList)                        {                            typeof(ToolStripItem).GetEvent("Click").RemoveEventHandler(item, del);                        }                    }

GetField的时候在原来的Name前面加"Event"前缀

GetField GetValue 的参数类型是Object类型可根据具体情况传入不同控件类型
