When I try adding Imports IO.System to the visual basic 2008 script contained in this article, I get the following error:

Namespace or type specified in the Imports 'IO.System' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.

Has anyone actually tried to run the script by Stan Kulp "Batch ETL of Multiple Data Files Using an SSIS Foreach Loop Container" ?
