Compressing and Decompressing Folders in C#

Question

I want to compress and decompress a folder using C#. The problem with GZipStream is that it takes filenames and hence I need to write a recursive logic.

Can I somehow do it like, give source folder name and destination filename to compress the complete folder with hierarchy. I need to do vice-versa for de-compressing the folder as well. If its not possible through C#/.net directly please suggest some Free 3rd party.

I've used the free SharpZipLib multiple times and I'd recommend that you take a look at it. It's quite easy to use and have worked well for all my use cases.

GZip only ever deals with single files, which is why under *nix you end up having to archive them into a TAR file first which is then compressed.

If you want multiple files/folders you'll need a format which supports it, like ZIP.

You might want to thus look at: http://www.sharpdevelop.net/OpenSource/SharpZipLib/
