Data return Json

Question

I have this function to return the data in JSON, but I’m not able to make it work in MVC Core.

 public ActionResult SalvarItens(string HoraInicio, string HoraFim, bool Seg, bool Ter, bool Qua, bool Qui, bool Sex, bool Sab, bool Dom, bool Fer, int Tipolimite, int Limiteacessos, int HorarioId)
        {
            var item = new HorariosItens()
            {
                HoraFim = HoraFim,
                HoraInicio = HoraInicio,
                Seg = Seg,
                Ter = Ter,
                Qua = Qua,
                Qui = Qui,
                Sex = Sex,
                Sab = Sab,
                Dom = Dom,
                Fer = Fer,
                Tipolimite = Tipolimite,
                Limiteacessos = Limiteacessos,
                HorarioId = HorarioId,
            };

            try
            {
                _context.HorariosItens.Add(item);
                _context.SaveChanges();
            }
            catch (Exception ex)
            {
                throw ex;
            }

            //return Json(new { Resultado = item.Id }, JsonRequestBehavior.AllowGet);
        }

This return Json(new { Resultado = item.Id }, JsonRequestBehavior.AllowGet); does not work on MVC Core, how can I convert to work?

Answer 1

Despite the same name the method Json(object data) in the Microsoft.AspNeCore.Mvc.JsonResult, that does not implement the argument of JsonRequestBehavior who was present System.Web.Mvc.JsonResult and eventually it was necessary to return the Json when access to the action was accomplished through a POST.

public ActionResult SalvarItens(string HoraInicio, string HoraFim, bool Seg, bool Ter, bool Qua, bool Qui, bool Sex, bool Sab, bool Dom, bool Fer, int Tipolimite, int Limiteacessos, int HorarioId)
{
    var item = new HorariosItens()
    {
        HoraFim = HoraFim,
        HoraInicio = HoraInicio,
        Seg = Seg,
        Ter = Ter,
        Qua = Qua,
        Qui = Qui,
        Sex = Sex,
        Sab = Sab,
        Dom = Dom,
        Fer = Fer,
        Tipolimite = Tipolimite,
        Limiteacessos = Limiteacessos,
        HorarioId = HorarioId,
    };

    try
    {
        _context.HorariosItens.Add(item);
        _context.SaveChanges();
    }
    catch (Exception ex)
    {
        throw ex;
    }

    return Json(new { Resultado = item.Id });
}
