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); } }
