recommend a library/API to unzip file in C#

Question

Hello everyone,

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?

thanks in advance, George

Answer 1

The LGPL

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.

Answer 2

Look for System.IO.Compression.GZipStream & System.IO.Compression.DeflateStream

Answer 3

SharpZipLib

http://www.icsharpcode.net/OpenSource/SharpZipLib/

Answer 4

If you want to use 7-zip compression, check out Peter Bromberg's EggheadCafe article. Beware: the LZMA source code for c# has no xml comments (actually, very few comments at all).

Answer 5

DotNetZip is easy to use. Here's an unzip sample

using (var zip = Ionic.Zip.ZipFile.Read("archive.zip")
{
   zip.ExtractAll("unpack-directory");
}

If you have more complex needs, like you want to pick-and-choose which entries to extract, or if there are passwords, or if you want to control the pathnames of the extracted files, or etc etc etc, there are lots of options. Check the help file for more examples.

DotNetZip is free and open source.

Answer 6

In the past, I've used DotNetZip (MS-PL), SharpZipLib (GPL), and the 7ZIP SDK for C# (public domain). They all work great, and are open source.

I would choose DotNetZip in this situation, and here's some sample code from the C# Examples page:

using (ZipFile zip = ZipFile.Read(ExistingZipFile))
{
  foreach (ZipEntry e in zip)
  {
    e.Extract(TargetDirectory);
  }
}

Answer 7

I would prefer SharpZiplib Please find the sample code to UnZip Files in .Net C#

Answer 8

Have a look to my small library: http://zipstorer.codeplex.com

Answer 9

I would recommend our http://www.rebex.net/zip.net/ but I'm biased. Download trial and check the features and samples yourself.
