Answer 1

Based on @Underscore post above, I created a list of properties to exclude on serialization.

public class DynamicContractResolver : DefaultContractResolver {
    private readonly string[] props;

    public DynamicContractResolver(params string[] prop) {
        this.props = prop;
    }

    protected override IList CreateProperties(Type type, MemberSerialization memberSerialization) {
        IList retval = base.CreateProperties(type, memberSerialization);

        // retorna todas as propriedades que não estão na lista para ignorar
        retval = retval.Where(p => !this.props.Contains(p.PropertyName)).ToList();

        return retval;
    }
}

Use:

string json = JsonConvert.SerializeObject(car, Formatting.Indented, 
    new JsonSerializerSettings { ContractResolver = new DynamicContractResolver("ID", "CreatedAt", "LastModified") });
