SimpleEntityValidation 1.1.1

SimpleEntityValidation

Why?

• Is very simple to use.
• You create your entity/class validation and can be used in any times.
• Whenever you need to validate a CLASS you don't need to repeat the validation.
• You can centralize your class validations in one place.

How i do?

• Just extend the abstraction class "AbstractValidation".
• Use the protected method "RuleFor" to setup the especifications of your field validations.

Example

• Client (Model)

	public class Client {
        public Guid Id { get; set; }
        public string Name { get; set; }
        public string Document { get; set; }
        public string Email { get; set; }
        public DateTime CreationDate { get; set; }
        public int YearsOld { get; set; }
        public string Password { get; set; }
        public string CheckPassword { get; set; }
        public List<string> Tags { get; set; }
    }	

• ClientValidator (Your Client Validator)

    public class ClientValidator : AbstractValidator<Client>
    {
        public ClientValidator() 
        {
            RuleFor(x => x.Name).NotNull().MinLength(5);

            RuleFor(x => x.Password).NotNull().MustBeEqual(x => x.CheckPassword);

            RuleFor(x => x.Email).NotNull().MinLength(10);

            RuleFor(x => x.Document).MaxLength(11);

            RuleFor(x => x.Password).NotEqual("12345");

            RuleFor(x => x.YearsOld).GreaterThan(17);

            RuleFor(x => x.Tags).NotNull();

            RuleFor(x => x.YearsOld)
                .LessThan(150)
                .WithMessage("The field 'YearsOld' is not less than '150'");
        }
    }

• Usage

    class Program
    {
        protected Program() { }

        static void Main(string[] args)
        {
            Client client = new() { Password = "12345", CheckPassword = "12312s1", YearsOld = 155 };

            ClientValidator clientValidator = new();
            
            ValidationResult result = clientValidator.Validate(client);

            if (result.ValidationFailures.Count > 0)
                Console.WriteLine("Client entity validation with errors:");

            result.ValidationFailures.ToList().ForEach(failure => Console.WriteLine($"{failure.Message}"));

            Console.ReadKey();
        }
    }

• Complex Class

    public class ClientValidator : AbstractValidator<Client>
    {
        public ClientValidator() 
        {
            RuleFor(x => x.Name).NotNull().MinLength(5);

            RuleFor(x => x.Password).NotNull().MustBeEqual(x => x.CheckPassword);

            RuleFor(x => x.Email).NotNull().MinLength(10);

            RuleFor(x => x.Document).MaxLength(11);

            RuleFor(x => x.CreationDate).NotNull();

            RuleFor(x => x.Tags).NotNull();

            RuleFor(x => x.Nums).NotNull();

            RuleFor(x => x.Password).NotEqual("12345");

            RuleFor(x => x.YearsOld).GreaterThan(17);

            RuleFor(x => x.Address).SetBaseValidator(new AddressValidator()); // Complex validation

            RuleFor(x => x.YearsOld)
                .LessThan(150)
                .WithMessage("The field 'YearsOld' is not less than '150'");
        }
    }

• Address Validator

    public class AddressValidator : AbstractValidator<Address>
    {
        public AddressValidator()
        {
            RuleFor(x => x.Street).NotNull().MaxLength(150);
            RuleFor(x => x.City).NotNull().MaxLength(100);
            RuleFor(x => x.Country).NotNull().MinLength(2);
        }
    }
