Adding Multiple Attachment (files) To A Dynamic Variable So It Can Be Send To A Email. VB 2010

What to use for adding multiple attachment to a email. I'm using VB 2010.

First, I have a Form in my company web site to fill a reclamation ..... when you fill and send it, it convert the form into a PDF, save it in the client side "TEMP" and finally get the PDF and send it to a email..... that's perfectly fine. I add to the form the capability of attach multiple files with file upload to the same "TEMP" and displayed in a Grid View to remove or add files and send everything to a email, the attachment capability is working. Everything is working with the PDF not the files(attachments).

There is a way to get the multiple files from the "TEMP" folder and add it to some dynamically variable (array list, attachment collection, list collection, etc.) so all can be send to the email. I already know the way to put it into the email with the PDF.

The problem is to get the files and add it to the dynamic variable and that it work with the email. If the code is need it.
