tinyvalidation

Extremely lightweight validation library for .NET, with very low CPU and memory consumption.

Get started

Use the NuGet Package Manager or the CLI to install:

dotnet add package TinyValidation

Example

Given the following class:

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

Create a validator using TinyValidation library:

public struct PersonValidator : ITinyValidator<Person>
{
    public readonly ValidationResult Validate(Person person)
    {
        return new Validate()
            .For(("Name", person.Name),   // (Property name, property value) 
                name => Tiny.NotEmpty(name), "Name is required")  //  => validation function, error message
            .For(("Name", person.Name), 
                name => Tiny.MaxLength(name, 80), "Name must be at most 80 characters.")
                
            .For(("Age", person.Age), 
                age => age > 0, "Age must be greater than 0")
            .Run();
    }
}

Register the validators for dependency injection:

builder.Services.AddTransient<ITinyValidator<Person>, PersonValidator>();

Or create a PersonValidator instance manually:

var personValidator = new PersonValidator();
