Class to process ZIP or CAB files

[Gaetan]

A summary search in MSDN did not produce anything.

Is there a class in .NET which allows management of ZIP or CAB files? Add/modify/remove
files in a specified CAB or ZIP file. I could always call an external process but I rather
do the ZIP/CAB file management from within my C# program.

Gaetan,

There is nothing in .NET 1.1 and before. You will have to use a third
party library (I think there is something galled SharpLib or something of
that nature which has been recommended a number of times).

For .NET 2.0, you can use the classes in the System.IO.Compression
namespace to zip/unzip zip archives.

For cab files, there is still no support, but I believe there are APIs
that you can use to access them. You should be able to call these through
the P/Invoke layer.

Hope this helps.

In .NET 2.0 there is the System.IO.Compression.GZipStream class

Thanks Nicholas for the prompt reply.

Although it is not what I was looking for, I found an article that could allow me to
manipulate ZIP files through C# calls to J#:

"Using the Zip Classes in the J# Class Libraries to Compress Files and Data with C#"

thanks again.

If you don't mind installing the J# runtime you can use the
java.util.zip.ZipEntry class.
There's a tutorial here:

Very little support for CAB files exists, either managed or unmanaged, so I
would stick with zip files if I were you.
