ASP.NET MVC 2 and ComponentModel.DataAnnotations Validation: minimum value attribute

Question

I'm decorated a ViewModel in my ASP.NET MVC 2 site with System.ComponentModel.DataAnnotations validation attributes. For one of my fields, named Price, I want to validate that the value is not below some extent, in this case 0.

I know that RangeAttribute exists for validation with a lower and an upper extent, but does something like a MinimumValueAttribute exist for validation with only a lower extent ?

If not, I guess I'll just roll my own.

Answer 1

在你自己滚动之前 - 尝试[Range(0.05, Double.MaxValue)]

Answer 2

不确定RegularExpression是否是“最佳”解决方案，但您可以试一试

"^\$?\d+(\.(\d{2}))?$"
