Getting data from the second row

Hi All,

In our DataSet the data comes in multiple rows.
we are able to fetch the data of the first row with
row["COLUMN_NAME"]. how can with fetch the data
of Second row.

for eg.
EMP_ID EMP_NAME DEPT_ID
1001 DAVE 10
1002 MARVERIK 20
2001 LOREN 10

if we write row["EMP_NAME"] we get DAVE
how can we get MARVERIK???

Thanx in advance.
