Manik.FluentValidationExtensions 1.0.0

FluentValidationExtensions A reusable C# library that extends FluentValidation by providing an extension method to convert ValidationResult errors to a dictionary. This helps developers easily access validation error details in a structured format, making it easier to work with validation errors across multiple projects.

Features Convert ValidationResult errors to a dictionary: Easily access validation errors in a dictionary format. Reusable across multiple projects: Package designed to be reusable across different .NET applications. Built with FluentValidation: The extension works with FluentValidation, a popular .NET validation library. Prerequisites .NET 8.0 or later FluentValidation (version 9.x or higher) Installation You can install this package via NuGet. Use the following command to add it to your project:

bash Copy code dotnet add package FluentValidationExtensions --version 1.0.0 Alternatively, you can search for the package in NuGet.org and install it through Visual Studio’s NuGet Package Manager.

Usage Once installed, you can easily convert the ValidationResult errors into a dictionary for better manipulation or display.

Example Usage Here’s an example demonstrating how to use the ValidationResultExtensions class.

Add FluentValidation to your project: bash Copy code dotnet add package FluentValidation Define a validator for your model: csharp Copy code using FluentValidation;

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

public class PersonValidator : AbstractValidator<Person> { public PersonValidator() { RuleFor(x ⇒ x.Name).NotEmpty().WithMessage("Name cannot be empty."); RuleFor(x ⇒ x.Age).GreaterThan(0).WithMessage("Age must be greater than 0."); } } Using ValidationResultExtensions to convert errors to a dictionary: csharp Copy code using FluentValidation; using FluentValidation.Results; using FluentValidationExtensions; // Import the extension namespace

public class Example { public static void Main() { var person = new Person { Name = string.Empty, Age = -1 };

    var validator = new PersonValidator();
    ValidationResult result = validator.Validate(person);

    // Convert ValidationResult errors to a dictionary
    var errors = result.ToDictionary();

    // Print the dictionary
    foreach (var error in errors)
    {
        Console.WriteLine($"{error.Key}: {error.Value}");
    }
}

} Example Output: plaintext Copy code Name: Name cannot be empty. Age: Age must be greater than 0. ValidationResultExtensions The extension method ToDictionary() is added to ValidationResult to help convert validation errors to a dictionary format:

csharp Copy code public static class ValidationResultExtensions { public static Dictionary<string, string> ToDictionary(this ValidationResult validationResult) { return validationResult.Errors.ToDictionary( error ⇒ error.PropertyName, error ⇒ error.ErrorMessage ); } } This method converts the list of validation errors in ValidationResult into a dictionary where the key is the property name and the value is the error message.
