import data from excel2007 sheet to slserver 2008 table in C#

You can use OPENDATASOURCE command

SELECT * FROM OPENDATASOURCE('Microsoft.Jet.OLEDB.4.0',
   'Data Source=c:\book1.xls;Extended Properties=Excel 8.0')...Sheet1$

Or creating a linked server to EXCEL file

Better way read on security of linked server from BOL
Linked Server Properties (Security Page)
