When mapping class to viewModel, some data is lost

Question

I have an appointment that returns a client and his phone, but when mapping the class to the viewModel, I lose phone data:

consultation:

public Cliente ObterClientePorId(Guid ClienteId)
{
      var consulta =
            Contexto.Cliente.Join(Contexto.Telefone,
                                  p => p.ClienteId, 
                                  pt => pt.ClienteId,
                                 (p, pt) => new {p, pt}).FirstOrDefault();

  if (consulta != null)
  {
      var cliente = consulta.p;
      cliente.telefone = consulta.pt;

      return cliente;
 }

But when mapping the client class to the viewModel cliente, it loses the data that was in telefone.

Mapping:

    public ClienteViewModel ObterClientePorId(Guid ClienteId)
    {
        //aqui tem os dados de telefone
        var consulta = _cliente.ObterClientePorId(ClienteId);
        //aqui o telefone fica null
        var cliente = Mapper.Map<Cliente, ClienteViewModel>(consulta);

        return cliente;
    }

ClienteViewModel:

public class ClienteViewModel
{
    public ClienteViewModel()
    {
        ClienteId = Guid.NewGuid();
    }

    // campos...

    public List<TelefoneViewModel> TelefoneViewModel { get; set; }

    //mais campos...
}

Have you tried mapping the Phone class to "Phoneviewmodel"? I say this because your class Clienteviewmodel has a List< Phoneviewmodel> and not List< Phone>.

Maybe this will work:

var telefones = Mapper.Map<List<Telefone>, List<TelefoneViewModel>>(consulta.telefone);
var cliente = Mapper.Map<Cliente, ClienteViewModel>(consulta);
cliente.TelefoneViewModel = telefones;

If it doesn’t work, share your Customer and Phone classes, please.
