The GZipStream and DeflateStream classes are wrappers around a normal Stream object. This means that you can extract the data as you’re going along before a) the whole file has been downloaded and b) without loading all of the data in to memory.
These are available in .NET 4 upwards, otherwise you’ll need to use #ZipLib as suggested.
EDIT:
After looking around it would appear that #ZipLib is definitely the way forwards with this. The same principles apply to these classes in that they are streams, they can work as the file is being downloaded or read over a network and they don’t require the whole file to be in memory. I’m currently using it in a project to open zip files from an http server, so I’ve seen it in action!
