Qowaiv exensions on *Fluent Validation

Validators

Required

The RequiredValidation validates that a required property has a set value. If specified, an unknown value can be seen as a set value, by default it is not.

public class CustomValidator : AbstractValidator<Model>
{
    public CustomValidator()
    {
        RuleFor(m => m.Email).Required();
        RuleFor(m => m.Iban).Required(allowUnknown: true);
    }
}

Not unknown

The UnknownValidation validates that a value does not equal the Unknown value (if existing of course). Accessible via the fluent syntax.

public class CustomValidator : AbstractValidator<Model>
{
    public CustomValidator()
    {
        RuleFor(m => m.Email).NotEmptyOrUnknown();
        RuleFor(m => m.Iban).NotUnknown();
    }
}

Relative to the clock

The ClockValidation validates if a date (time) is in the past, or future. It supports Date, DateTime, Date?, and DateTime?, and the provision of custom date (time) provider. By Default, Clock.Now() and Clock.Today() are used.

public class CustomValidator : AbstractValidator<Model>
{
    public CustomValidator()
    {
        RuleFor(m => m.Date1).InFuture();
        RuleFor(m => m.Date2).InPast();
        RuleFor(m => m.Date3).NotInFuture();
        RuleFor(m => m.Date4).NotInPast(() => CustomeDateProvider());
    }
}

Postal code valid for specific country

The PostalCodeValidation validates that a PostalCode value is valid for a specific Country, both static and via another property.

public class CustomValidator : AbstractValidator<Model>
{
    public CustomValidator()
    {
        RuleFor(m => m.PostalCode).ValidFor(m => m.Country);
    }
}

Finite floating points

The FloatingPointValidation validates that double and float values are finite numbers.

public class CustomValidator : AbstractValidator<Model>
{
    public CustomValidator()
    {
        RuleFor(m => m.Number).IsFinite();
    }
}

Email address should not be IP-based

The EmailAddressValidation validates that an EmailAddress does not have an IP-based domain.

public class CustomValidator : AbstractValidator<Model>
{
    public CustomValidator()
    {
        RuleFor(m => m.Email).NotIPBased();
    }
}
