Create Excel worksheet in .Net

[Brian Johnson]

I am trying to create multiple (named) worksheets in excel
using .Net PIA's. I have successfully created an excel
document and set cell values, but have been unable to
manipulate which worksheet I am using and naming the
worksheet.

Here is current sample (VB.Net):
dim xl as new excel.application()
xl.workbooks.Add()
xl.cells(1,1).Value = "test"

Any help or pointing to some documentation would be
helpful!

Thanks.
