Hello

Anyone have any exeriance using C# and pkunzip? I'm writing up a C# app
that may have to extract files from a .ZIP archieve. The files will be
zipped up, and I'll need to unzip hem and put them in the path there are
zipped up in. My question how can i do that, or is it possiable?

I've not had to do it in C# yet, but I've used this product in the past with
Clarion.

Friedrich Linder writes some fantastic stuff, and is very responsive when
asked questions. I wouldn't hesitate to use anything he wrote.

He says on his website this works with C++, so if he doesn't have a C#
version you could still use it with InteropServices.

You should be able to do that using either the J# lib or
the open source #ZipLib.

I believe I have some examples if you are interested.

have a look at:
http://www.icsharpcode.net/OpenSource/SharpZipLib/

alternatively, you can hook into the J# library which comes with Zip Support
out of the box

I've used this (free) library before without problems :

http://www.codeplex.com/DotNetZip

The command line add-on makes it easy to zip & unzip from your program

What makes it better than the gratis alternatives.

DotNetZip is one of those gratis alternatives for handling ZIP files.
It's a 100% managed code library to read, create, and update zip files
from within any .NET application.
It does zip passwords, zip passwords with AES encryption, ZIP64,
Unicode, self-extracting archives, and more. There's a good help file
with lots of examples (online version here:http://
cheeso.members.winisp.net/DotNetZipHelp/ ). There's also a support
forum on codeplex.

Here's some sample code to extract all files from a zip to a
particular directory, without overwriting existing files:

String TargetDirectory= "c:\\unpack";
using(Ionic.Zip.ZipFile zip= Ionic.Zip.ZipFile.Read
(ZipFileToExtract))
{
zip.ExtractAll(TargetDirectory,
Ionic.Zip.ExtractExistingFileAction.DontOverwrite);
}

Sample to extract entries conditionally, and overwrite any existing
files:

using (var zip1 = Ionic.Zip.ZipFile.Read(zipToUnpack))
{
foreach (var entry in zip1)
{
// extract only the entries I want:
if (wantExtract(entry.FileName))
entry.Extract(dir,
Ionic.Zip.ExtractExistingFileAction.OverwriteSilently);
}
}


Sample code to create a zip file, zipping up a directory:

using (var zip = new Ionic.Zip.ZipFile())
{
zip.AddDirectory(directory, System.IO.Path.GetFileName
(directory));
zip.Save(targetZip);
}

Sample to create a self-extracting archive (SFX):
using (var zip = new Ionic.Zip.ZipFile())
{
zip.AddDirectory(directory, System.IO.Path.GetFileName
(directory));
zip.Comment = "This will be embedded into a self-extracting
console-based exe";
zip.SaveSelfExtractor("archive.exe",
SelfExtractorFlavor.ConsoleApplication);
}

DotNetZip can also produce a Windows GUIs for the SFX.
