Zip utility to zip directory contents

How can I zip the contents of a directory programmatically

GZipStream zips and unzips files, is there some way to manipulate this to zip a directory (recursively)

Is there another .NET utility out there

I'm developing in C#.

Thanks.

If you're using .Net 2.0, you can use the GZip or Deflate streams.

See http://msdn2.microsoft.com/en-gb/library/system.io.compression.gzipstream.aspx for an example or lookup GZipStream class in your help.

If you have .Net 1.x, you'll need some help. I liked to use SharpZipLib at http://www.icsharpcode.net/

.NET 2.0.
I've been playing with same example but it looks to me like it's only for Zipping single files!

How can I unzip an existing .zip file (it will contain various files) replace some of the files and then rezip

Did you take a look at sharpziplib I believe it has the ability to zip a directory.
