实体框架：设置更新时间戳 [英] Entity Framework: Setting update timestamp

问题描述

我们所有的数据库表都有UpdateUserID和UpdateTS。如果我的实体有更改，我想进行设置。有什么方法可以让我有条件地当场进行此更新吗？

All of our database tables have UpdateUserID and UpdateTS. I'd like to have this set if my entity has changes. Is there a way I can have this update on the spot conditionally?

如果我在代码中手动设置UpdateTS，那么它将表明我的实体已更改并且将始终更新对象。

If I manually set UpdateTS in code, then it will say that my entity has changed and will always update the object.

推荐答案

您应该能够处理SavingChanges事件（此处的示例）并执行@sander概述的逻辑

You should be able to handle the SavingChanges event (example here) and perform logic as outlined by @sander
