Phone 验证属性无效

Question

我正在尝试验证一些用户联系方式，如下所示：

public class Customer
{
    [Display(Name = "Your e-mail :")]
    [Required(ErrorMessage = "An email address is required")]
    [EmailAddress(ErrorMessage = "Invalid Email Address")]
    public string ContactEmail { get; set; }    

    [Display(Name = "Your contact number :")]
    [Required(ErrorMessage = "A phone number is required")]
    [Phone(ErrorMessage = "Invalid Phone Number")] 
    public string ContactNumber { get; set; }

}

在我看来，电子邮件验证效果很好，只允许有效的电子邮件地址。但是，phone 验证根本不起作用，它允许各种字母和特殊字符。

文档指出 PhoneAttribute class

Specifies that a data field value is a well-formed phone number using a regular expression for phone numbers

那为什么这没有发生呢？

Answer 1

使用以下代码进行 Phone 验证。

[Display(Name = "Your contact number :")]
[Required(ErrorMessage = "A phone number is required.")]
[DataType(DataType.PhoneNumber, ErrorMessage = "Invalid Phone Number")]
[RegularExpression(@"^([0-9]{10})$", ErrorMessage = "Invalid Phone Number.")]
public string ContactNumber { get; set; }
