Dyanmically create Hyperlinks to all files in a folder using ASP.net VB

Currently using Visual Studio to create a Intranet site for very small office. We have a project folder in the Web Project that I would like to dynamically create hyperlinks for on a asp.net page. I would like to either use the Page Load or a Refresh button on the page to go read the folder & (Sub Folders if possible) and create hyperlinks for the documents. All of the documents are PDF files. The documents are updated or augmented  on regular basis.

I'm a newbie at this programming thing so looking for a simple approach if there is one. Looking for sample code or a good starting point and some directions. Your help would be greatly appreciated.
