recommend a library/API to unzip file in C#
.net, c#, zip
Solution
The GPL
http://www.icsharpcode.net/OpenSource/SharpZipLib/
OR the less restrictive Ms-PL
http://www.codeplex.com/DotNetZip
To complete this answer the .net framework has ZipPackage I had less success with it.
Problem
Looks like no built-in Library/API in C# to unzip a zip file. I am looking for a free (better open source) library/API which could work with .Net 3.5 + VSTS 2008 + C# to unzip a zip file and extract all files into a specific folder. Any recommended library/API or samples?
