Error while converting JSON

Question

While converting my data I get the following error:

Input string '42.0' is not a Valid integer

This error happens because I get a value string "42.0" in a field int -> Con_codigo

How can I solve??

My code:

using (HttpResponseMessage response = await httpClient.GetAsync(UrlApi2))
{
    response.EnsureSuccessStatusCode();
    string resul = await response.Content.ReadAsStringAsync();
    ListaContatos = JsonConvert.DeserializeObject<List<ContatosViewModel>>(resul);
}

Meu Json:

[
  {
    "Con_tpcadastro": "BAN",
    "Con_codigo": 42.0,
    "Con_nome": "ASD",
    "Con_vinculo": "SAD",
    "Con_fone": "ASD",
    "Con_fax": "ASD",
    "Con_celular": "ASDAS",
    "Con_email": "DAS"
  },
  {
    "Con_tpcadastro": "BAN",
    "Con_codigo": 42.0,
    "Con_nome": "FDS",
    "Con_vinculo": "SDF",
    "Con_fone": "FSD",
    "Con_fax": "FSD",
    "Con_celular": "FSD",
    "Con_email": "SDF"
  }
]

Contacts:

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Threading.Tasks;

namespace SoftluxWebCore.ViewModels.Tabelas.Financeiro
{
public class ContatosViewModel
{
    public string Con_tpcadastro { get; set; }

    [Display(Name = "Código")]
    public int? Con_codigo { get; set; }

    [Display(Name = "Nome")]
    [Required(ErrorMessage ="Informe o Nome do Contato")]
    public string Con_nome { get; set; }

    [Display(Name = "Vinculo")]
    public string Con_vinculo { get; set; }

    [Display(Name = "Fone")]
    public string Con_fone { get; set; }

    [Display(Name = "FAX")]
    public string Con_fax { get; set; }

    [Display(Name = "Celular")]
    public string Con_celular { get; set; }

    [Display(Name = "Email")]
    public string Con_email { get; set; }

}

}

Jeff, I believe the class to which your object belongs "Contact lists" own a name property "Code". This property needs to be to type decimal to receive this kind of value.
