Question

在我的MVC 4应用程序中，我需要在帐户注册屏幕上进行验证;密码包含至少1位数，1个大写＆amp; 1个小写字符。我希望模型类属性类似于

[Display(Name = "Register_Password", ResourceType = typeof(VirtuOxAdmin))]
    [Required(ErrorMessageResourceType = typeof(VirtuOxAdmin), ErrorMessageResourceName = "Register_PasswordRequired")]
    [MinLength(5, ErrorMessageResourceType = typeof(VirtuOxAdmin), ErrorMessageResourceName = "Admin_CreateCustomer_PasswordMinLength")]
    [MaxLength(32, ErrorMessageResourceType = typeof(VirtuOxAdmin), ErrorMessageResourceName = "Admin_CreateCustomer_PasswordMaxLength")]
    [RegularExpression(@"\d", ErrorMessageResourceType = typeof(VirtuOxAdmin), ErrorMessageResourceName = "Admin_CreateCustomer_AtleastOneDigit")]
    [RegularExpression("[A-Z]+", ErrorMessageResourceType = typeof(VirtuOxAdmin), ErrorMessageResourceName = "Admin_CreateCustomer_AtleastOneUChar")]
    [RegularExpression("[a-z]+", ErrorMessageResourceType = typeof(VirtuOxAdmin), ErrorMessageResourceName = "Admin_CreateCustomer_AtleastOneLChar")]
    public string Password { set; get; }

但我收到错误错误重复'RegularExpression'属性

我如何编码密码验证？

您必须将所有元素组合成一个正则表达式。为此，您可以使用零宽度预测断言。这样的事情应该有效：

(?=.*[a-z])(?=.*[A-Z])(?=.*\d)

MVC 4中的多个RegularExpression属性
