Any native ZIP/Packaging for .NET3.5

I am looking for Zip/Unzip 开发者_如何学运维operation in my .NET application. I can see plenty of third party implementations, But is there one part of .NET framework?

Or let me tell you what exactly I am looking for. I may just need to package a folder and need to give a particular extension to it.

System.IO.Packaging

The J# library (no longer supported) includes zip/unzip routines. Be careful with gzip as it is a single-file compression stream and has no concept of files or directories. Some folks have reported (limited) success with the cabarc tools but they're not .NET.
