在基类中实现 INotifyPropertyChanged 或类似的自定义事件

有没有办法做到这一点：

我需要开发最简单的方法来支持注册某些类的属性更改。除了手动添加 INotifyProperyChanged 支持之外，还有一种方法可以这样做：

class Base ... // all notification logic here

class Child
{
    public string Name { get; set; }
    public int SomeNumber { get; set; }
    // etc....
}

这样我就可以执行 Child.PropertyChanged += some_handler 并仅在 Child 属性更改时收到通知。这不适用于 NHibernate 或其他任何东西，它是供整个项目中手动使用的。我研究了一些使用 Castle Dynamic Proxy 执行此操作的示例（例如这里），但我不明白如何利用它:(

当然想探索一般的框架和 AOP，我只是现在没有足够的时间......

谢谢如有任何意见请提前...

Is there a way to do this:

I need to develop the easiest way to support registering to property changes of some class. Apart from manual way of adding INotifyProperyChanged support, is there a way to do it like this:

class Base ... // all notification logic here

class Child
{
    public string Name { get; set; }
    public int SomeNumber { get; set; }
    // etc....
}

so that I can do Child.PropertyChanged += some_handler and be notified only on Child property changes.
This isn't for NHibernate, or anything else, it is for manual use in entire project. I have looked into some examples of doing this with Castle Dynamic Proxy (like here), but I don't understand how to exploit it :(

Sure would like to explore there frameworks and AOP in general, I just don't have enuogh time right now ...

Thank you in advance for any comments...
