#ziplib (SharpZipLib) is a Zip, GZip, Tar and BZip2 library written entirely in C# for the .NET platform.

The #ziplib (SharpZipLib) is a Zip, GZip, Tar and BZip2 library written entirely in C# for the .NET platform. It is implemented as an assembly (installable in the GAC), and thus can easily be incorporated into other projects (in any .NET language). The creator of #ziplib put it this way: "I've ported the zip library over to C# because I needed gzip/zip compression and I didn't want to use libzip.dll or something like this. I want all in pure C#."

Reference: http://www.icsharpcode.net/opensource/sharpziplib/

Installation

SharpZipLib can most easily be installed through its NuGet package.

Install-Package SharpZipLib
