问题描述

如何使用ctp5对属性进行更改验证，是否可以提供样本？

How do you do property changed validation with ctp5, can you provide a sample?

推荐答案

如果要在设置时验证新值，则可以在属性设置器中包含验证逻辑。如果要在保存时进行验证，则可以在属性上使用数据注释，它们将在保存时进行验证，包括自定义
验证属性。您还可以在DbContext上覆盖ValidateEntity以在保存时执行自定义验证。

If you want to validate new values as they are set then you can include validation logic in your property setter. If you want validation to occur on save then you can use Data Annotations on your properties and they will be validated on save, including custom validation attributes. You can also override ValidateEntity on DbContext to perform custom validation at save.
