MYCE.FluentValidator

MYCE (Makes Your Coding Easier) FluentValidator is a fluent validation library designed to simplify entity validation in .NET applications.

Supports net6.0, net8.0, net9.0, and netstandard2.0.

Installation

Package Manager Console:

Install-Package Myce.FluentValidator

Features

  • FluentValidator: Fluent validation class for entities
  • ValidatorBuilder: Orchestrates multiple validations in a single process

Usage

1. Create your Entity

public class Person
{
   public string Name { get; set; }
   public int Age { get; set; }
   public string Email { get; set; }
   public string Code { get; set; }
}

2. Define Validation Rules

Use the FluentValidator to define rules for your entity properties.

var person = new Person { Name = "John Doe", Age = 30, Email = "john.doe@example.com", Code = "A123" };

var validator = new FluentValidator<Person>();
    .RuleFor(x => x.Name)
        .IsRequired()
        .MinLength(3)
        .MaxLength(50)
    .RuleFor(x => x.Age)
        .IsGreaterThanOrEqualTo(18)
        .IsLessThanOrEqualTo(100)
    .RuleFor(x => x.Email)
        .IsRequired()
        .IsValidEmailAddress()
    .RuleFor(x => x.Code)
        .ExactNumberOfCharacters(4)
        .ContainsOnlyNumber();

var result = validator.Validate(person);

if (validator.Messages.Any())
{
    foreach (var message in validator.Messages)
    {
        Console.WriteLine(message.Text);
    }
}

Supported Validators

Validator Description
Contains Validates that the value exists within a provided collection.
ContainsOnlyNumber Validates that a string contains only numeric characters.
ExactNumberOfCharacters Validates that a string has an exact length.
ExactNumberOfCharactersIf Validates exact length if a condition is true.
IsEqualTo Validates equality to a specific value.
IsGreaterThan Validates that the value is greater than a specified value.
IsGreaterThanOrEqualTo Validates that the value is greater than or equal to a specified value.
IsLessThan Validates that the value is less than a specified value.
IsLessThanOrEqualTo Validates that the value is less than or equal to a specified value.
IsNotEqualTo Validates if the property value is not equal to a fixed value.
IsRequired Validates that the property is not null or empty.
IsRequiredIf Validates that the property is required if a condition is true.
IsNotNull Validates if the property value is not null.
IsNull Validates if the property value is null.
IsValidDate Validates that a string can be parsed as a valid date.
IsValidEmailAddress Validates that a string is a valid email format.
MaxLength Validates the maximum length of a string.
MaxLengthIf Validates maximum length if a condition is true.
MinLength Validates the minimum length of a string.
MinLengthIf Validates minimum length if a condition is true.

Notes

  • Version 1.1.1 adds new validators: IsNotNull, and IsNull.
  • Version 1.1.0 introduces multi-targeting support (net6.0, net7.0, net8.0, net9.0, and netstandard2.0) and full nullability support.
  • Version 1.0.0 was the initial release of Myce.FluentValidator, providing basic validation capabilities for .NET applications.

Dependencies

  • Myce.Extensions
  • Myce.Response
