NHibernate：为什么非持久属性必须标记为虚拟才能延迟加载
我了解到为了允许延迟加载，NHibernate 需要生成一个扩展 POCO 类的代理类。所以我猜 NHibernate 需要重写持久化属性的实现，并且你必须将它们标记为虚拟的。
我不明白的是为什么我必须把几乎所有其他东西都标记为虚拟。例如，我必须标记一个 IsValid 属性，该属性引用其他属性，但显然本身不是持久的，而且奇怪的是，我也必须将该类可以发出的所有事件标记为虚拟。
有谁知道这是为什么吗？我只是好奇。
谢谢

I kind of get that in order to allow lazy loading, NHibernate needs to generate a proxy class which extends the POCO class. And so I guess NHibernate needs to override the implementation of the persisted properties, and you have to mark them as virtual.
What I don't get is why I have to go round marking almost everything else as virtual as well. For example, I had to mark an IsValid property, which refers to the other properties but obviously isn't itself persistent, and bizarrely I had to mark all the events the class can emit as virtual too.
Anyone know why this is? I'm just curious.
Thanks
David
