Old code C # decompress and compress the ZIP file to save it as a collection ~~

Note: This code is a little bug, so you have to use it together ~~ Bug1: If duplicate files exist, a window indicating whether to overwrite the files is displayed on the server. Therefore, do not duplicate the directories when extracting files. Bug2: it is the compression time. Similarly, there should be no duplicate names. In addition, at the beginning, create a zip file, copy it, and add it to it. The overall idea is that it can be used together. Haha ~~

 

The Code is as follows .. Copy it from the Internet, and change it by yourself ~~
