unzipping files

[Paul Brownjohn]

Hi Guys

I need a dll that just unzips zipped files...does anyone know of a freeware
or cheapo shareware one that does this. I know there are quite a lot of
rather sophisticated ones out there that do achiving and password protection
and create achives and bells and whistles but they are $100+ and I am
reluctant to pay for all that functionality when I don't need it...I just
want to unzip non-password protected achives

There is also a win32 API for doing this if you don't want to rely on the JSharp runtime. Take a look at
http://msdn.microsoft.com/library/de...single_file.as

In particular, the LZOpenFile function and it's related calls

Hmm...that's something I haven't tried and didn't know you could do. This is
I take it, a standard Win API call, nothting to do with the .NET framework.
How do you use a a standard API call from within C#?

Cheers

SharpZipLib comes up quite often, which I'm sure will do what you want.

Unless I'm missing some documentation, these APIs do not deal with Zip
archives - these APIs are used to compress or decompress individual files.

yes, this is true. This API only works on single files compressed via LZ. However, Paul originally asked for a cheapo way to decompress that doesn't involved password protection or archiving. It won't work for actual zip archives
