You can write a Generic function to check Null and include default value when it is NULL. Call this when reading Datareader

public T CheckNull(object obj)
        {
            return (obj == DBNull.Value ? default(T) : (T)obj);
        }

When reading the Datareader use

                        while (dr.Read())
                        {
                            tblBPN_InTrRecon Bpn = new tblBPN_InTrRecon();
                            Bpn.BPN_Date = CheckNull(dr["BPN_Date"]);
                            Bpn.Cust_Backorder_Qty = CheckNull(dr["Cust_Backorder_Qty"]);
                            Bpn.Cust_Min = CheckNull(dr["Cust_Min"]);
                         }
