如何范围验证整数ASP.NET MVC 3

Question

我正在使用如下验证.

[Required(ErrorMessage = "Please provide 10 digit mobile number without spaces and without country code (+91)")]
[Integer(ErrorMessage = "Please provide 10 digit mobile number without spaces and without country code (+91)")]
[Range(1000000000, 9999999999, ErrorMessage = "10 digit mobile number only without spaces and without country code (+91)")]
[Display(Name = "Mobile Number")]
public int MobileNo { get; set; }

验证总是失败The value '9999999998' is invalid..难道我做错了什么？

Answer 1

试试这个:

[RegularExpression("^[0-9]{10}$", ErrorMessage = "Invalid Mobile No")]

Answer 2

,一个最大值的Int32类型可以存储为2,147,483,648.你满溢了.为什么使用整数类型来表示电话号码？字符串似乎更适应.
