Convert model to another model with List

  • 772

I have two identical models:

Model 1

public class Modelo
{
    public string IdModelo { get; set; }
    public List<DatosModelo> Datos { get; set; }
}

public class DatosModelo
{
    public string IdModelo { get; set; }
    public string Title { get; set; }
    public string Value { get; set; }
}

Model 2 

public class ModeloBD
{
    public string IdModelo { get; set; }
    public List<DatosModeloBD> Datos { get; set; }
}

public class DatosModeloBD
{
    public string Title { get; set; }
    public string Value { get; set; }
}

To convert model 2 to model 1 I have tried with:

List<ModeloBD> data = _svcConfiguracion.GetOperaciones(4);
List<Modelo> transformar = data.Select(ToVm());

public Modelo ToVm(ModeloBD modelo)
{
    return new Modelo
    {
        IdModelo = modelo.IdModelo,
        Datos = modelo.Datos.Select(ToVm) // Intento aqui realizar la transformacion de la lista de datos y falla
    };
}

public DatosModelo ToVm(DatosModeloBD datos)
{
    return new DatosModelo
    {
        Title = datos.Title,
        Value = datos.Value
    };
}

Is there a way to do it without having to split it?

    The best way to convert data structures is using the libraryAutoMapper

    AutoMapper nuget

    with this libraries you could define how the entities are converted

    Getting StartedGuide

    then you define the mapping

    var config = new MapperConfiguration(cfg => {
    cfg.CreateMap<ModeloBD, Modelo>();
    cfg.CreateMap<DatosModeloBD, DatosModelo>();
});

var mapper = config.CreateMapper();

List<ModeloBD> data = _svcConfiguracion.GetOperaciones(4);

var transformar = mapper.Map<List<ModeloBD>, List<Modelo>>(data);

    to be able to use the Map<>()and convert from one type to another mapped
