Unzipping a file error?

Question

I have used this code given by Marc Gravell in SO to unzip a file

and got this error in this line while ((myEntry = s.GetNextEntry()) != null)

ICSharpCode.SharpZipLib.Zip.ZipException: Wrong Local header signature: 0xAFBC7A37

Any Suggestion??

It *sounds* like your zip is possibly corrupt... - or maybe your stream just isn't at the right place when starting. A bit hard to tell with this little context, though. — Marc Gravell, Dec 02 '10 at 11:02

Given that hex codes 37 7A equate to the letters '7z', it looks like you've got a file in 7Zip format.

This answer may help you access it from .NET: How do I create 7-Zip archives with .NET?

You need to download 7-Zip, which is different from WinZip: http://www.7-zip.org/ – Tim Robinson Dec 03 '10 at 10:13
