Question

我正在为我的表设置水晶报表，我按照所有说明修复了加载报表失败，对temp文件夹甚至文件路径提供了完全控制权限，但仍然出现错误：加载报表失败，'CrystalDecisions .Shared.CrystalReportsException'

这是我的代码

public ActionResult OccupiedReport()  
    {
        List<ReservationModel.OccupiedStatus> Occupied = new List<ReservationModel.OccupiedStatus>();
        string constr = ConfigurationManager.ConnectionStrings["MyCnn"].ConnectionString;
        using (MySqlConnection con = new MySqlConnection(constr))
        {
            string query = "SELECT * FROM room_status WHERE check_out >= CURDATE() and status ='occupied'";
            using (MySqlCommand cmd = new MySqlCommand(query))
            {
                cmd.Connection = con;
                con.Open();
                using (MySqlDataReader sdr = cmd.ExecuteReader())
                {
                    while (sdr.Read())
                    {
                        Occupied.Add(new ReservationModel.OccupiedStatus
                        {
                            DormName = sdr["Dorm_Name"].ToString(),
                            RoomNumber = sdr["Room_Number"].ToString(),
                            BedNumber = sdr["Bed_Number"].ToString(),
                            GuestName = sdr["Guess_Name"].ToString(),
                            Classification = sdr["Classification"].ToString(),
                            Gender = sdr["Gender"].ToString(),
                            CheckIn = sdr["Check_In"].ToString(),
                            CheckOut = sdr["Check_Out"].ToString(),
                            StatusType = sdr["Status"].ToString()
                        });
                    }

                }
                con.Close();
                ReportDocument rd = new ReportDocument();
                rd.FileName = Server.MapPath("/CrReport/CrystalReport1.rpt");
                rd.Load(Server.MapPath("~/CrReport/CrystalReport1.rpt"));
                rd.SetDataSource(Occupied);

                Response.Buffer = false;
                Response.ClearContent();
                Response.ClearHeaders();


                Stream stream = rd.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);
                stream.Seek(0, SeekOrigin.Begin);
                return File(stream, "application/pdf", "CustomerList.pdf");

            }
        }


    }

CrystalDecisions.CrystalReports.Engine.dll中发生了类型'CrystalDecisions.Shared.CrystalReportsException'的异常，但未在用户代码中处理

其他信息：加载报告失败。

听起来好像报告路径有问题，请在这里尝试建议：code project

或者，如果那不是问题，那么计算机中是否安装了多个版本的CR？因为那会引起类似这样的问题。尝试取消安装并重新安装正确的版本。
