How to do further manipulation on sql procedure records using CLR

Hello everyone. I am newbie to CLR integration while developing an understanding to CLR integration in c#.net for stored procedure in sql server 2008 i am caught in a problem. for a better understanding first take a look at this fictitious data.

Qty   price 

2        10

3         9

4         20

now i have this data in my store procedure's query  on which i would like to perform further manipulation using CLR integration which is to Calculate Total=Qty*Price for each row for sake of understanding CLR integration.

once the calculation in managed code is done then i would like sql server to the following as resultset not as a message.

Though i have achieved this with SqlDataRecord which give me one record/ per resultset which is not what i want. I want these three rows to occur like following in only one result set.

Qty   price    Total

2        10        20

3         9         27

4         20       80

How can i achieve this in CLR integration using c#.net.
Your guidance will greatly be appreciated.

Thanks in Advance.
