数据变更事件，泛型类，体会其中思想

数据变更事件
namespace Feng.FramWorkDesign
{
    public class BindableProperty<T> where T: IEquatable<T>
    {
        private T mValue = default(T);

        public T Value
        {
            get
            {
                return mValue;
            }
            set
            {
                if (!value.Equals(mValue))
                {
                    mValue = value;
                    onValueChanged?.Invoke(mValue);
                }
            }
        }

        public Action<T> onValueChanged;
    }
}

泛型

namespace Feng.FramWorkDesign
{
    public class Event<T> where T :Event<T>
    {
        private static Action mUnPaseEvent;

        public static void Register(Action onEnven)
        {
            mUnPaseEvent += onEnven;
        }

        public static void UnRegister(Action unEvent)
        {
            mUnPaseEvent -= unEvent;
        }

        public static void Trigger()
        {
            mUnPaseEvent?.Invoke();
        }
    }
}

相互衬托，思考其中的作用，MVC设计   在交互逻辑当中去触发表现逻辑
