Download zipped files

[Amelyan]

I have a bunch of files I need to put into Compressed (zipped) Folder,
MyFiles.zip file, similarly to what Windows XP does when you send files to
compressed zipped folder, so users can download MyFiles.zip from my ASP.NET
2.0 site. What is the simplest way to compress these files into a .zip?

I found System.IO.Compression, but I am not sure how to use it to do what I
need to do. Does anyone have an example of how to send a bunch of files
into compressed (zipped) folder?

Thanks,
