获取实体更改？ [英] Get entity changes?

问题描述

是否有可能确切地知道在EF4和POCO模式下对实体做了哪些更改？

我知道我可以通过调用找出已更改/删除/更新的实体等检测变化并从objectstatemanager获取条目。

但是我还能以某种方式找到个别变化吗？

Is it possible to find out exactly what changes have been made to an entity in EF4 and POCO mode?

I know I can find out what entities have been changed/deleted/updated etc by calling detect changes and get the entries from the objectstatemanager.

But can I also find the individual changes somehow?

推荐答案

当您从ObjectStateManager获取条目时，您还可以从相同的ObjectStateEntry实例获取有关哪些属性已更改以及原始值的信息。 br /> - Danny

When you get the entries from the ObjectStateManager, you can also get information about which properties have changed and the original values all from the same ObjectStateEntry instances.
