CNPJValidatorV2

Uma biblioteca C# moderna para validação, formatação e cálculo de dígito verificador de CNPJs.

✨ Funcionalidades

  • ✅ Validação completa de CNPJs com e sem formatação
  • 🧮 Cálculo automático dos dígitos verificadores (DV)
  • 🧼 Sanitização de entrada (remove caracteres inválidos)
  • 🧾 Formatação no padrão 00.000.000/0000-00

🚀 Instalação

Instale via NuGet:

dotnet add package CNPJValidatorV2

🔍 Exemplo de uso

using CNPJValidatorV2.Core;

// Verifica se um CNPJ é válido
bool valido = CNPJValidator.IsValid("12.345.678/0001-95"); // true

// Sanitiza um CNPJ
string cnpj = "12.345.678/0001-95".SanitizeCNPJ(); // "12345678000195"

// Formata um CNPJ simples
string formatado = "12345678000195".FormatCNPJ(); // "12.345.678/0001-95"

// Calcula o DV a partir de um número base (com ou sem letras)
string cnpjComDV = CNPJValidator.CalculateDV("12ABC34501DE"); // "12ABC34501DE35"

// Calcula e já formata
string formatadoComDV = CNPJValidator.CalculateDV("12ABC34501DE").FormatCNPJ(); // "12.ABC.345/01DE-35"

✅ Testes automatizados

Este projeto possui testes com xUnit que cobrem:

  • Validação de CNPJs reais
  • Cálculo correto dos dígitos verificadores
  • Detecção de CNPJs malformados
  • Comparações com valores esperados
  • Testes de formatação

Execute os testes com:

dotnet test

⚠️ Erros tratados

O método CalculateDV lança exceção se o CNPJ tiver menos de 12 caracteres alfanuméricos:

Assert.Throws<ArgumentException>(() => CNPJValidator.CalculateDV("123"));
