Need to zip files via VB.NET...help

[MotoMan_Yz400]

I'm making a back-up program that will need to compress many files into a TAR file before sending them off. Is there a command-line based program I can shell to, to get this done? Or possible call something directly from VB.NET? I know there are alot of programs like WinZIP and winRAR, but I need something very light weight with minimal impact to the system.

For command line tools, you could try IZArc

Or you could try SharpZipLib which is a .Net library that you could add to your project

I've posted code that shows how to use SharpZipLib in the VB.NET CodeBank forum.

That was for an older version but what's there should still be valid.

There's also another post in the CodeBank forum that uses Java types via J#. This may seem advantageous as you don't need a third-party library. That said, you would need to install the J# redistributable along with your app, which is larger than the SharpZipLib library. Also, J# has been discontinued by Microsoft so there may be issues as a result at some point.
