How can I zip more than 1 file in a GZipStream? I have 3 xml files and I want to zip them into one .gz file and when I decompress I should get all 3 separate files.
How can I do this?

gzip is only designed to hold a single file. You will need to collate them in some other container before gzipping them.

He's saying the same thing as Matthew - you'll need to combine the three files into one file *before* you compress. – Charlie Salts Jun 15 '10 at 03:23

1First you pick a container, like, say, JSON. Then you create a JSON string containing the three files. And then you compress the JSON string. – Ignacio Vazquez-Abrams Jun 15 '10 at 03:36

You can tar them together first. SharpZipLib has support for tar, as well as its own GZip implementation. See the SharpZipLib.Tar namespace. The docs are here.

is it a microsoft library or 3rd party?? coz my client does not accept third parties... – Sathish Jun 15 '10 at 03:13

It's third-party class. That seems like a rather arbitrary requirement. – Matthew Flaschen Jun 15 '10 at 03:15

You can see [this question](http://stackoverflow.com/questions/940582/how-do-i-zip-a-file-in-c-using-no-3rd-party-apis). But note that ZipPackage isn't a general-purpose Zip class. – Matthew Flaschen Jun 15 '10 at 03:20
