Qowaiv DataAnnotations based validation
Provides an data annotations based implementation of the Qowaiv.Validation.Abstractions.IValidator
and data annotation attributes.
Annotated model validator
The AnnotatedModelValidator
validates a model using its data annotations.
It returns a Result<TModel>
of the validated model:
var validator = new AnnotatedModelValidator<SomeModel>();
Result<SomeModel> result = validator.Validate(model);
Validation messages
Qowaiv.Validation.DataAnnotations.ValidationMessage
inherits Microsoft's
ValidationResult
, and implements Qowaiv.Validation.Abstractions.IValidationMessage
.
This allows the creation of messages with different severities:
var none = ValidationMessage.None;
var info = ValidationMessage.Info(message, args);
var warn = ValidationMessage.Warning(message, args);
var error = ValidationMessage.Error(message, args);
Validation attributes
Multiple [System.ComponentModel.DataAnnotations.Validation]
attributes can be
used to decorate models.
Mandatory
The [Required]
attribute does not work for value types. The [Mandatory]
attribute does. The default value of the struct
is not valid. It also is not
valid for the Unknown value, unless that is explicitly allowed.
public class Model
{
[Mandatory(AllowUnknownValue = true)]
public EmailAddress Email { get; set; }
[Mandatory()]
public string SomeString { get; set; }
}
Any
The [Required]
attribute does not work (well) for collections. The [Any]
attribute does. It is only valid if the collection contains at least one item.
public class Model
{
[Any()]
public List<int> Numbers { get; set; }
}
Allowed values
The [AllowedValues]
attribute allows to define a subset of allowed values. It
supports type converters to get the allowed values based on a string value.
public class Model
{
[AllowedValues("DE", "FR", "GB")]
public Country CountryOfBirth { get; set; }
}
Forbidden values
The [ForbiddenValues]
attribute allows to define a subset of forbidden values. It
supports type converters to get the forbidden values based on a string value.
public class Model
{
[ForbiddenValues("US", "IR")]
public Country CountryOfBirth { get; set; }
}
Defined enum values only
The [DefinedEnumValuesOnly]
attribute limits the allowed values to defined
enums only. By default it supports all possible combinations of defined enums
when dealing with flags, but that can be restricted by setting
OnlyAllowDefinedFlagsCombinations
to true.
public class Model
{
[DefinedEnumValuesOnly(OnlyAllowDefinedFlagsCombinations = false)]
public SomeEnum CountryOfBirth { get; set; }
}
Distinct values
The [DistinctValues]
attribute validates that all items of the collection are
distinct. If needed, a custom IEqualityComparer
comparer can be defined.
public class Model
{
[DistinctValues(typeof(CustomEqualityComparer))]
public IEnumerable<int> Numbers { get; set; }
}
Is finite
The [IsFinite]
attribute validates that the floating point value of the field
represents a finite (e.a. not NaN, or infinity).
public class Model
{
[IsFinite]
public double Number { get; set; }
}
Multiple of
The [MultipleOf]
attribute validates that the value of a field is a multiple
of the specified factor.
public class Model
{
[MultipleOf(0.001)]
public Amount Total { get; set; }
}
Optional
The [Optional]
attribute indicates explicitly that a field is optional.
public class Model
{
[Optional]
public string? Message { get; set; }
}
