c# - FileResult + redirectToAction出现错误

Question

有时我在调用Web服务以获取凭证且Web服务为KO时出现错误。我需要重定向到其他操作:我需要执行以下操作:

  public virtual FileResult Ticket(int operationCategoryId, int orderId)
    {
        try
        {
            var orderDetail = _orderDetailBusiness.GetOrderDetail(operationCategoryId, orderId);
            byte[] ticketContent = _vpTicketMinuteBusiness.GetTicketContent(orderDetail.Parcels);
            return File(ticketContent, "application/pdf", orderId + ".pdf");
        }
        catch (NullReferenceException exception)
        {
            return RedirectToAction("Error");
        }

    }

我怎样才能做到这一点？

尝试这个:

 return new FileStreamResult(ms, "application/ms-excel")
            {
                FileDownloadName = "yourfile.xlsx",
            };
