Directory: giving full control in C#

Question

I have this code in C# for giving full control to any file, it works excellent.

But how can I give full control to any directory?

Code to give full access to a file:

string fileName = @"d:\MyFile.mdb";
FileSecurity fSecurity = File.GetAccessControl(fileName);
fSecurity.AddAccessRule(new FileSystemAccessRule("Everyone", FileSystemRights.FullControl, AccessControlType.Allow));
File.SetAccessControl(fileName, fSecurity);

In exactly the same way, but using Directory.GetAccessControl instead of File.GetAccessControl:

DirectorySecurity dirSec = Directory.GetAccessControl("C:\\temp");
dirSec.AddAccessRule(new FileSystemAccessRule("Everyone", FileSystemRights.FullControl, AccessControlType.Allow));
Directory.SetAccessControl("c:\\temp", dirSec);

You're launching program not as Administrator? – Anton May 21 '12 at 12:41
i think that i Administrator, but if not - is there any way to run the program as Administrator ? – Gali May 21 '12 at 13:08
Getting closer. now added the "Everyone" group to the folder, but the permissions show up blank; nothing granted. – Gali May 21 '12 at 13:44

Here's an example:

        DirectoryInfo myDirectoryInfo = new DirectoryInfo(@"C:\Dir1\");

        DirectorySecurity myDirectorySecurity = myDirectoryInfo.GetAccessControl();

        string User = System.Environment.UserDomainName + "\\" + "Everyone"; 

        myDirectorySecurity.AddAccessRule(new FileSystemAccessRule(User, 
                                          FileSystemRights.FullControl, 
                                          AccessControlType.Deny)); 

        myDirectoryInfo.SetAccessControl(myDirectorySecurity);
