Create and extract .zip files in C#

Sadly there aren’t many flexible or efficient ways to create .zip files in .NET prior to .NET 4.5. Thankfully some people took the initiative and created some very easy to use libraries for creating/extracting and updating .zip files. My two all time favourite are DotNetZip and SharpZipLib.

For this example I will be using the DotNetZip library.

First you will need to download the library (.dll) either from http://dotnetzip.codeplex.com/ or from http://www.fluxbytes.com/?dl_name=DotNetZipLib_v1.9.1.8.rar. The file should contain quite a few libraries, so choose the one that suits your needs the most and add it as a reference in your project.

I’ve constructed two methods for this example, one suitable for creating a .zip file with any files or folders you give it as an argument and one for extracting the contents of a .zip file to any location you want.

Create .zip file method:

Usage:

Extract .zip file method:

Usage:


And there you have it, just a few lines of code in order to create or extract a .zip file!
