# Polish Validators for C#

Library for validation of Polish NIP, PESEL, REGON for C# (.NET Standard)

## Description

Most validation algorithms are published separate. They differ only in weights and checksum function.

That's why I decided to write a simple implementation for C# using **Template Method** design pattern.

## Get Started

PolishValidators can be installed using the Nuget package manager or the dotnet CLI.

~~~ 

Install-Package PolishValidators

~~~

~~~ 

dotnet add package PolishValidators

~~~

## Usage

~~~ csharp

IValidator validator = new PeselValidator();

bool result = validator.IsValid("49040501580");

~~~

~~~ csharp

IValidator validator = new NipValidator();

bool result = validator.IsValid("9531204591");

~~~

## Custom Validator

You can easily create a new validator. 

Just use abstract class _ValidatorBase_ and override _Weights_ and sum control function like this:

~~~ csharp

public class CustomValidator : ValidatorBase

{

    protected override byte[] Weights => new byte[] { 1, 5, 7, 9, 1, 5, 7, 9, 5, 3 };

    protected override int CheckControl(int sumControl) => 10 - sumControl % 10;

}

~~~

Good luck :)

## Route constraints 

If you are looking for route constraints for MVC or Razor Pages projects then I invite you my another project using PolishValidators library:
