in a three layer application how can I send returned fields from sdr in business layer to higher layer?
I tried this using a class but I want know if there is another way except declaring a class for each select statement in data layer.

In this example I used PaySlip Class.

public Class_PaySlip ReadPaySlip(string prsnlcod,string company,int _month,int _year)
        {
            lasterror = string.Empty;
            var lst = new List<SqlParameter>();
            lst.Add(new SqlParameter("@prsnlcod", prsnlcod));
            lst.Add(new SqlParameter("@company", company));
            lst.Add(new SqlParameter("@month", _month));
            lst.Add(new SqlParameter("@year", _year));

            var PaySlip = new Class_PaySlip();
            try
            {
                using (SqlDataReader sdr = dbh.Read("reportpersonpaySlip", CommandType.SP, lst))
                {
                    if (dbh.lasError == string.Empty)
                    {
                        if (sdr != null)
                        {
                            if (sdr.Read())
                            {
                                PaySlip = (CatchPaySlip(sdr,prsnlcod,company,_month,_year));
                            }
                            sdr.Close();
                            return PaySlip;
                        }
.                       
.
.

Initilizing Payslipclass:

 private Class_PaySlip CatchPaySlip(SqlDataReader sdr,string prsnlcod,string company,int _month,int _year)
        {
            Class_PaySlip PaySlip = new Class_PaySlip();
            PaySlip.Gender = ((DBNull.Value) == sdr["Gender"]) ? string.Empty : sdr["Gender"].ToString();
            PaySlip.EmpType = ((DBNull.Value) == sdr["EmploymentType"]) ? string.Empty : sdr["EmploymentType"].ToString();
.
