FluentValidation is validation library for .NET that uses a fluent interface and lambda expressions for building strongly-typed validation rules.
Supporting the project
If you use FluentValidation in a commercial project, please sponsor the project financially. FluentValidation is developed and supported by @JeremySkinner for free in his spare time and financial sponsorship helps keep the project going. You can sponsor the project via either GitHub sponsors or OpenCollective.
Example
With FluentValidation, you can define a class that inherits from AbstractValidator
which contains the rules for a particular class. The example below shows how you could define rules
for a Customer class, and then how to execute the validator.
using FluentValidation;
public class CustomerValidator: AbstractValidator<Customer> {
public CustomerValidator() {
RuleFor(x => x.Surname).NotEmpty();
RuleFor(x => x.Forename).NotEmpty().WithMessage("Please specify a first name");
RuleFor(x => x.Discount).NotEqual(0).When(x => x.HasDiscount);
RuleFor(x => x.Address).Length(20, 250);
RuleFor(x => x.Postcode).Must(BeAValidPostcode).WithMessage("Please specify a valid postcode");
}
private bool BeAValidPostcode(string postcode) {
// custom postcode validating logic goes here
}
}
var customer = new Customer();
var validator = new CustomerValidator();
// Execute the validator.
ValidationResult results = validator.Validate(customer);
// Inspect any validation failures.
bool success = results.IsValid;
List<ValidationFailure> failures = results.Errors;
