[WinForm]移除控件某个事件

关键代码:

        /// <summary>        /// 移除控件某个事件        /// </summary>        /// <param name="control">控件</param>        /// <param name="eventName">需要移除的控件名称eg:EventClick</param>        public static void RemoveControlEvent(this Control control, string eventName)        {            FieldInfo _fl = typeof(Control).GetField(eventName, BindingFlags.Static | BindingFlags.NonPublic);            if (_fl != null)            {                object _obj = _fl.GetValue(control);                PropertyInfo _pi = control.GetType().GetProperty("Events", BindingFlags.NonPublic | BindingFlags.Instance);                EventHandlerList _eventlist = (EventHandlerList)_pi.GetValue(control, null);                if (_obj != null && _eventlist != null)                    _eventlist.RemoveHandler(_obj, _eventlist[_obj]);            }        }

使用代码:

        private void WinRemoveControlEventTest_Load(object sender, EventArgs e)        {            button1.RemoveControlEvent("EventClick");        }        private void button1_Click(object sender, EventArgs e)        {            MessageBox.Show("button1_Click");        }
