Reference: full control over C #

I have this code in C # for complete control of any file, it works fine.

But how can I fully control any directory?

Code providing full access to the file:

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

Similarly, but using Directory.GetAccessControlinstead File.GetAccessControl:

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

Here is 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);
