Getting nulls on executing Stored Procedure in web api but getting result in MSSQL

Question

I have a stored procedure that gives me this output in MSSql Server

So I created a class to catch this output like so:

public class OwnerInfo
{
    public string UnitName { get; set; }
    public string UnitOwner { get; set; }
}
public class FirstInfo
{
    public string TType { get; set; }
    public string TransactionType { get; set; }
    public string Period_Covered { get; set; }
    public double? BillAmount { get; set; }
    public double? PaymentAmount { get; set; }
    public double? Balance { get; set; }
}
public class SecondInfo
{
    public string TType { get; set; }
    public string TransactionType { get; set; }
    public string Period { get; set; }
    public double? BillAmount { get; set; }
    public double? PaymentAmount { get; set; }
    public double? Balance { get; set; }
}
public class ThirdInfo
{
    public string TType { get; set; }
    public string TransactionType { get; set; }
    public string Period { get; set; }
    public double? PaymentAmount { get; set; }
}
public class FourthInfo
{
    public string TType { get; set; }
    public string Particulars { get; set; }
    public string PaymentDate { get; set; }
    public double? PaymentAmount { get; set; }
    public string ORNumber { get; set; }
}
public class DisplaySoa
{
    public OwnerInfo OwnerInfo { get; set; }
    public List<FirstInfo> FirstInfo { get; set; }
    public List<SecondInfo> SecondInfo { get; set; }
    public List<ThirdInfo> ThirdInfo { get; set; }
    public List<FourthInfo> FourthInfo { get; set; }
}
public class DisplaySoaParameter
{
    public int UnitID { get; set; }
    public int Month { get; set; }
    public int Year { get; set; }
}

And the way I get it from the database is in my controller and I call the stored procedure like so:

const string query = "[dbo].[DISPLAY_SOA_V4] @UnitID, @Month, @Year";
            using(var db = new ApplicationDbContext())
            {

                try
                {
                    //const string query = "[dbo].[DUES_AUTO_PAYMENT] @PaymentAmount @PaymentTypeID @ORNumber @UnitID @CurrentDateTime";
                    object[] parameter =
                    {
                        new SqlParameter
                        {
                            ParameterName = "@UnitID",
                            Value = model.UnitID,
                            Direction = ParameterDirection.Input,
                            SqlDbType = SqlDbType.Int
                        },
                        new SqlParameter
                        {
                            ParameterName = "@Month",
                            Value = model.Month,
                            Direction = ParameterDirection.Input,
                           SqlDbType = SqlDbType.Int
                        },
                        new SqlParameter
                        {
                            ParameterName = "@Year",
                            Value = model.Year,
                            Direction = ParameterDirection.Input,
                            SqlDbType = SqlDbType.Int
                        }
                    };

                    var x = db.Database.SqlQuery<DisplaySoa>(query, parameter).ToList();
                    return x;
                }
                catch (Exception ed)
                {
                    return null;
                }
            }

but in my "x" value I get null like so:

That image is when I use .FirstOrDefault() bur if I use .ToList(), I get a count of 1 but nothing is insede i .Can you please help me with this? Thank you.

Answer 1

Your sp is returning multiple result sets.

var x = db.Database.SqlQuery<DisplaySoa>(query, parameter).ToList();

From this you can't handle that.

Please read this article for how to do that.
