I need help and guidence towards learning material to build a
directory search utility into my asp.net page. I have a Directory
called "Trusses" with many subdirectories. I want the user to be able
to put in a Codenumber and the aspx page will take every subdirectory
that mathhes that number exactly and make it a catagory on the page
and make every file a link under that catagory to open the file. All
files are PDF.

I am new at the .NET platform and would greatly appreciate some
guidance on this topic.
