I'm working on an existing zip archive, and trying to save changes to it.
One of the operations I do during the save, is to add the content of some directory, again and again every time I save.
I get "an item with the same key has already been added" exception when using AddSelectedFiles:
_zipFile.AddSelectedFiles(excludeList, dirPath, "", true);
It is possible that some entries that the save is now adding, already exist, obviously, but I just want to add them anyway but I didn't see how I can overwrite them.
BTW, when the zip file is a new one, and doesn't contain any entries, there's no problem.
Any idea how to solve this?
