数据标注/验证和动态值 [英] Data Annotation/Validation and dynamic values
问题描述
如果我的一些型号的具有动态验证条件(即字符串长度可以取决于一个数据库值或一些其它动态值8或12的最小值)是它不可能用数据注解为验证?
If some of my models have dynamic validation conditions (i.e. the string length can be minimum of 8 or 12 depending on a database value or some other dynamic value) is it impossible to use data annotation for validation?
据我了解,任何参数的值(例如StringLength最小值/最大值)必须是真正静态的。是否有应用具有动态验证值的替代品?
From what I understand, the values of any parameter (example StringLength min/max value) have to be truly static. Are there alternatives for applications that have dynamic validation values?
推荐答案
您pretty多坚持写自己的自定义validationattribute:
