asp.net MVC 4 SSN验证

Question

我正在使用ASP.NET MVC 4,我正在寻找SSN验证的属性.

[Required(ErrorMessage = "Social Security is Required")]
[SSN]
public string SSN { get; set; }

我知道这不起作用,但这正是我要找的.

谁能帮忙

Answer 1

你需要使用正则表达式.尝试这样的事情.

[Required(ErrorMessage = "SSN is Required")]
[RegularExpression(@"^\d{9}|\d{3}-\d{2}-\d{4}$", ErrorMessage = "Invalid Social Security Number")]
public string SSN { get; set; }
