C # settings and get directory permissions (. NET control ACL)

You want to use C # to set up and read directory permissions on NTFS partitions, and find a lot of information. Finally found a section of vb.net code, made changes to C # to show you.

With MSDN, it's easy to read the code above. But it looks like this program needs to run as an administrator. ^_^
