Send list of objects JSON c #

. However, in the controller, I only get the Field id, and nothing from Answer , I can not see the problem. My array can get the data as it should, just not everything is passed to the controller.

JSON

var urlResposta = '@Url.Action("Create", "Resultado")';
var dtoEnvio = new Array();
            $('.resposta').each(function () {
                var obj = {
                        Resposta: {
                            Resp: $(this).find('.perg-resp').first().val()
                        },
                        Campo: { Id: $(this).find('#hidID').first().val() }
                    };
                dtoEnvio.push(obj);
            });
            console.log(dtoEnvio)

        $.ajax({
            type: "POST",
            url: urlResposta,
            cache: false,
            data: JSON.stringify(dtoEnvio),
            datatype: 'json',
            contentType: "application/json; charset=utf-8",
            success: function (result) {
            }
        })
    };

    {
        public virtual Int64 Id { get; set; }

    }
