Cab file compression

[GeoffreyD]

Hi

Is there a way that I could use the .net framework to extract from and
compress using the legacy cab compression system (without having to buy 3rd
party licenses)? My company uses this type of compression to support older
windows PCs (pre-.net) as we can be sure that the OS is always able to
handle the compression.

Thanks

There is an opensource solution called Sharpzip that may provide a
solution and is free to down load and use. It works great and has good
documentation with examples on usage.

Did you search? It only took me about 30 seconds:

Hi

Thanks for the reply. I currently use Sharpziplib in another of my projects
and have found it very useful. Unfortunately it only supports zip, gzip, tar
and bzip2.

Hey this task is not so simple as meets the eye (or perhaps I should have
been a little clearer that I was looking for a purely .net solution - no
unmanged code interop). We already have a standard c++ (unmanaged)
implementation for this and are not really wanting a more complex solution
(although granted in this case the interop work is kind of done already).
This doesn't really help in an environment where we are trying to convince
other developers to make the switch over to .net

So, any purely .net solutions out there for cab compression?

Well,
there is an awful lot of unmanaged code interop in the .NET Framework, so
you should not let this scare you. I have never heard of a 100% managed code
implementation of the CAB file API.

Hi GeoffreyD,

As Peter said, there's no pure .NET implementation of CAB library.
