🚀 Características

  • Métodos de extensión simples:
    • MapTo<TDest>() → crea un objeto destino a partir de la fuente.
    • MapFrom(source) → rellena una instancia existente.
  • Atributos personalizables:
    • [MapIgnore] → ignora propiedades.
    • [MapName("OtraPropiedad")] → alias entre nombres diferentes.
  • Conversión de tipos incluida:
    • Nullables (int?, DateTime?, etc.).
    • Enums ↔ string/números.
    • Guid, DateTime, decimal, TimeSpan, etc.
  • Colecciones: convierte IEnumerable<T> a List<TDestino>.
  • Mapeo recursivo: objetos complejos son mapeados propiedad por propiedad.
  • Convertidores personalizados: registra tus propias funciones de conversión entre tipos.

🧑‍💻 Uso rápido

using GenericMapper;

var user = new User
{
    Id = 7,
    FullName = "Ada Lovelace",
    CreatedAt = DateTime.UtcNow,
    Address = new Address { Street = "St. James's", City = "London" },
    Roles = new List<Role> { Role.Admin, Role.User }
};

// Entidad → DTO
var dto = user.MapTo<UserDto>();

// DTO → Entidad
var user2 = dto.MapTo<User>();

// Mapear sobre instancia existente
user2.MapFrom(new UserDto { Id = 7, Name = "Ada Byron" });

🛠️ Ejemplo de atributos

public sealed class UserDto
{
    public int Id { get; set; }
    [MapName("FullName")] // Mapear FullName de la entidad hacia Name del DTO
    public string Name { get; set; } = string.Empty;
    public string CreatedAt { get; set; } = string.Empty;
    public AddressDto? Address { get; set; }
    public List<string> Roles { get; set; } = new();
}

🔧 Convertidores personalizados

MappingExtensions.RegisterConverter<Role, string>(r => r.ToString());
MappingExtensions.RegisterConverter<string, Role>(s => Enum.Parse<Role>(s, true));

📂 Estructura recomendada
