i need to zip some files and folders. is there a function already done for this or how can i go about doing this?

Hi, I think there is no ZipInputStreams and ZipOutputStream in Dot Net Libraries. It is available in some third party Libraries.

This Zip Library completely implemented in .NET Managed Code. It is free to use in free or commercial products.
