Как взять значение из таблицы?

using (SqlDataReader sqlDataReader = await sqlCommand.ExecuteReaderAsync())
{
    while (await sqlDataReader.ReadAsync())
    {
        works.Add(new LaborHBWork
        {
            IDLaborWork = (int)sqlDataReader["ID_LaborHB_02"],
            IDLaborType = (int)sqlDataReader["ID_LaborHB_01"],
            PosNumber = (int)sqlDataReader["PosNum"],
            NameOfWork = sqlDataReader["NameOfWork"] as string ?? "",
            WorkCode = sqlDataReader["WorkCode"] as string ?? "",
            Labor = (decimal)sqlDataReader["Labor"],
            LaborAssembly = sqlDataReader["LaborAssembly"] ==
                DBNull.Value ? null : (decimal?)sqlDataReader["LaborAssembly"],
            ErectCoeff = (decimal)sqlDataReader["ErectCoeff"]
        });
    }
}

    while (await sqlDataReader.ReadAsync())
    {
        works.Add(new LaborHBWork
        {
            IDLaborWork = (int)sqlDataReader["ID_LaborHB_02"],
            IDLaborType = (int)sqlDataReader["ID_LaborHB_01"],
            PosNumber = (int)sqlDataReader["PosNum"],
            NameOfWork = sqlDataReader["NameOfWork"] as string ?? "",
            WorkCode = sqlDataReader["WorkCode"] as string ?? "",
            Labor = (decimal)sqlDataReader["Labor"],
            LaborAssembly = sqlDataReader["LaborAssembly"] ==
                DBNull.Value ? null : (decimal?)sqlDataReader["LaborAssembly"],
            ErectCoeff = (decimal)sqlDataReader["ErectCoeff"]
        });
    }
