public class TestClass
{
    private const string EMP_ID = "EmpId";
    public void MyTestMethod()
    {
        //GetData fetches data from the database using a SQL query
        DataTable dt = DataAccess.GetTableData();
        DataColumn dcEmpId = dt.Columns[EMP_ID];
        foreach (DataRow dRow in dt.Rows)
        {
            //Accessing data through datacolumn
            int empId = Convert.ToInt32(dRow[dcEmpId]);
        }
    }
}
