retrieving data from excel file in ASP.NET

Hi,
I have a problem.
I need to get data from excel file and then create a query and report.
I can't get to the point where I can use the excel file like database
with more tables(sheets).

So I do not need to write to an excel file, i just need to use the xml
file like database.

Thanks in advance,

Best regards,
buga
