EventHandler 只是一个例子。。项目中用的是DeviceHandler这个不能修改

Answer 2

public static Delegate[] GetObjectEventList(object p_Object, string p_EventName, Type p_EventType)
        {
            PropertyInfo _PropertyInfo = p_Object.GetType().GetProperty("Events", BindingFlags.Instance | BindingFlags.NonPublic);
            if (_PropertyInfo != null)
            {
                object _EventList = _PropertyInfo.GetValue(p_Object, null);
                if (_EventList != null && _EventList is EventHandlerList)
                {
                    EventHandlerList _List = (EventHandlerList)_EventList;
                    FieldInfo _FieldInfo = p_EventType.GetField(p_EventName, BindingFlags.Static | BindingFlags.NonPublic | BindingFlags.IgnoreCase);
                    if (_FieldInfo == null) return null;
                    Delegate _ObjectDelegate = _List[_FieldInfo.GetValue(p_Object)];
                    if (_ObjectDelegate == null) return null;
                    return _ObjectDelegate.GetInvocationList();
                }
            }
            return null;
        }
