本文实例讲述了WinForm实现移除控件某个事件的方法,供大家参考借鉴一下。具体功能代码如下:
主要功能部分代码如下:
/// <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"); }
