获取“ System.IndexOutOfRangeException”

Question

错误：

  

System.IndexOutOfRangeException    在   System.Data.ProviderBase.FieldNameLookup.GetOrdinal（字符串fieldName）   在System.Data.SqlClient.SqlDataReader.GetOrdinal（String name）在   System.Data.SqlClient.SqlDataReader.get_Item（字符串名称）位于

我更改了存储过程以将两个新列添加到结果中，该存储过程本身似乎正常工作，但是当我将新列添加到m = 8 n = 73 multiple <- function(n, m){ # your suggested solution # } 时遇到此错误

型号

SQlDataReader

我的方法

public class StudentRecordFull : StudentRecord
{
    public double CreditProgress { get; set; }
    public string EnrollmentStatus { get; set; }
    public int IsEnrolled { get; set; }
    public string YRQLastAttended { get; set; }
    public int Mandatory { get; set; }
    public double GPA { get; set; }
    public string TotalPrint { get; set; }
    public int Balance { get; set; }

}

public StudentRecordFull GetStudent(int sid)
    {
        StudentRecordFull s = new StudentRecordFull();
        using (SqlConnection myConnection = new SqlConnection(ProductionDataConnString))
        {
            SqlCommand myCommand = new SqlCommand("usp_GetStudent", myConnection);
            myCommand.CommandType = CommandType.StoredProcedure;
            SqlParameter SIDParameter = myCommand.Parameters.Add("SID", SqlDbType.Char, 9);
            SIDParameter.Value = sid;

            myConnection.Open();
            using (SqlDataReader oReader = myCommand.ExecuteReader())
            {
                while (oReader.Read())
                {
                    s.SID = SafeGetString(oReader, "SID");
                    s.FirstName = SafeGetString(oReader, "FirstName");
                    s.LastName = SafeGetString(oReader, "LastName");
                    s.AdvisorName = SafeGetString(oReader, "Advisor");
                    s.AdvisorSID = SafeGetString(oReader, "AdvisorSID");
                    s.PathwayName = SafeGetString(oReader, "PathwayName");
                    s.PathwayID = SafeGetInt(oReader, "PathwayId");
                    s.SubPathwayID = SafeGetInt(oReader, "SubPathwayId");
                    s.SubPathwayName = SafeGetString(oReader, 
                                                      "SubPathwayName");
                    //s.TotalPrint = SafeGetString(oReader, "ploplo");
                    s.Credits = SafeGetInt(oReader, "CreditsEarned");
                    s.Phone = SafeGetString(oReader, "DaytimePhone");
                    s.DOB = SafeGetString(oReader, "DOB");
                    s.Address = SafeGetString(oReader, "Address");
                    s.City = SafeGetString(oReader, "City");
                    s.State = SafeGetString(oReader, "State");
                    s.Zip = SafeGetString(oReader, "Zip");
                    s.Email = SafeGetString(oReader, "Email");
                    s.CreditProgress = SafeGetDouble(oReader, 
                                           "CreditProgress");
                    s.EnrollmentStatus = SafeGetString(oReader, 
                                           "EnrollmentStatus");
                    s.IsEnrolled = SafeGetInt(oReader, "IsEnrolled");
                    s.YRQLastAttended = SafeGetString(oReader, 
                                            "YRQLastAttended");
                    s.Mandatory = SafeGetInt(oReader, "Mandatory");
                    s.GPA = SafeGetDouble(oReader, "GPA");
                    s.Balance = SafeGetInt(oReader, "Balance");
                    //s.TotalPrint = SafeGetString(oReader, "TotalPrint");

                }
                myConnection.Close();
            }
        }
        return s;
    }

如果我删除新列，那么一切正常，就像无法读取那些列。

有什么主意吗？
