Create a new sheet and copy the first 3 rows from the first sheet in c#.net

Hi

I need to write the content of 1000 records in an excel using the excel object in c#.net.

In one excel i need to write only 100 records and if the record exceeds more than 100 record i need to create a new sheet and have to write the content but the need is, i have designed a header in the first 3 rows of the header in the first excel and i need write to the first 3 rows in the 2nd sheet also.

Can any one give me a link or idea to achive this.
