Hi,

you can use the GZipStream class:
http://msdn.microsoft.com/en-us/library/system.io.compression.gzipstream.aspx[^]

but as I remember this feature of .NET requires that the files/folders were zipped with GZipStream too. It can't handle unzipping normal zip files.
To unzip normal archives, you should use an external component such as the SharpZipLib library:
