在C＃中将文件添加到zip中

Question

I'm trying to add a file to a zip without creating a new zip .

I already tried using multiple libraries but none of them could do this without recreating a completely new zip file. The library i'm using is DotNetZip

Why I want to this is because i'm working with really big zip files and I just want to modify a existing file in the zip.

Well, ZIP components of our SecureBlackbox don't create new ZIP when you add or delete a file from existing ZIP. Ie the stream is modified in-place.
