I need to fill pointer to SECURITY_DESCRIPTOR with dota that will represent descriptors of certain files and folders. I use FileSecurity object set some properties and then use GetSecurityDescriptorBinaryForm. On the other end of that when my descriptor should be read it gets an error that revision number other than 1 is invalid. How to set that number either in FileSecurity or binaryform?
Thanks in advance.

Try something like this:

C#

SECURITY_ATTRIBUTES lpSecurityAttributes = new SECURITY_ATTRIBUTES();
DirectorySecurity security = new DirectorySecurity();
lpSecurityAttributes.nLength = Marshal.SizeOf(lpSecurityAttributes);
byte[] src = security.GetSecurityDescriptorBinaryForm();
IntPtr dest = Marshal.AllocHGlobal(src.Length);
Marshal.Copy(src, 0, dest, src.Length);
lpSecurityAttributes.lpSecurityDescriptor = dest;

Found the code in the article Manipulating NTFS Junction Points in .NET[^] Its a good read and may just do the trick for you.
