How can I control the positon of a newly added worksheet added via C?

When I use the published code

ThisWorkbook.Worksheets.Add( Type.Missing, Type.Missing, Type.Missing,
Type.Missing)

it inserts the new Worksheet after the Active Worksheet. I want to control
exactly where it is inserted, probably I can tell by the parameters but
don't have any explanation. I tried several things but getting error
messages only.
