Question

I’m using MVC and I want to validate the phone No

I wrote this class:

public class StudentValidator : AbstractValidator<graduandModel>
{
    public StudentValidator(ILocalizationService localizationService)
    {
        RuleFor(x => x.phone).NotEmpty().WithMessage(localizationService.GetResource("Hire.HireItem.Fields.phone.Required"));
    }
}

How can I validate the phone number inside this class?

Can I use the following?

RuleFor(x => x.phone).SetValidator(....)

If so how can I use it??

Answer 1

Have you considered using DataAnnotations in your model?

Something like this:

[DataType(DataType.PhoneNumber, ErrorMessage = "Invalid Phone Number")]
public string PhoneNumber { get; set; }

Another solution would be the use of regular expressions:

[DisplayName("Phone number")]
[Required(ErrorMessage = "Phone number is required")]
[RegularExpression(@"((\(\d{3}\) ?)|(\d{3}-))?\d{3}-\d{4}", ErrorMessage = "Invalid phone number")]
