序列化数据注释
我想将 DataAnnotations 存储在数据库中。如何通过反射（或其他方式）检索 DataAnnotation 的字符串表示形式？
示例
public class Product
{
[DisplayName("Price")]
[Required]
[RegularExpression(@"^\$?\d+(\.(\d{2}))?$")]
public decimal UnitPrice { get; set; }
}
结果可以是 XML 或 JSON 数据，只要它是字符串化的。
I would like to store DataAnnotations inside a database. How can I retrieve a string representation of a DataAnnotation by reflection (or by other means)?
Example
public class Product
{
[DisplayName("Price")]
[Required]
[RegularExpression(@"^\$?\d+(\.(\d{2}))?$")]
public decimal UnitPrice { get; set; }
}
Result could be XML or JSON data as long as it is stringified.

这与 retrieve-custom-attribute-parameter-values 非常相似，我会将其用作您的解决方案的基础
this is very similar to retrieve-custom-attribute-parameter-values, i'd use it as a basis for your solution
您最好编写自己的验证提供程序，然后以更方便的形式将验证规则存储在数据库中。解析字符串以尝试实例化属性似乎比必要的工作更多。 :)

You'd be better off writing your own validation provider, and then just store the validation rules in your database in a more convenient form. Parsing the strings to try to instantiate the attributes seems like more work than necessary. :)
