将文件删除到文件夹 c#

Question

I have a problem very curiosity.

I am delete files into folders this is the algoritm

            System.IO.DirectoryInfo di = new DirectoryInfo(folderPath);

            foreach (FileInfo file in di.GetFiles())
            {
                file.Delete();
            }
            foreach (DirectoryInfo dir in di.GetDirectories())
            {
                dir.Delete(true);
            }

I choose the directory and the algorithm deletes: folders, subfolders and everything related without problem.

The problem occurs when I download a compressed file, which has folders and subfolders (it is important to mention, that the data in the compressed file is what I should actually delete).

and the software reports an error: Access denied

The truth is that I do not understand, the files of that compressed (.zip) specifically some folders of that compressed file are the ones that will not let me delete.

Is there something missing in the algorithm that allows deletion?

At first, to recursively delete folder with all files and subfolders you can just call Directory.Delete(folderPath, true) . As described in documentation , you can have UnauthorizedAccessException if file or folder is protected. One of solutions you can do is to require your application to launch with admin privilegies as described in answer https://stackoverflow.com/a/2818776/10115818
