How to assign access rights "Everyone" to a directory

Question

I encounter a problem to assign access rights to "Everyone" on a directory folder "wwwroot" on windows from my little programm in C#. Here's how I do it.

//I also try with 'S-1-1-0'/'Everyone' but it's the same result 
string userPermission = "Everyone"  ;

DirectoryInfo myDirRoot = new DirectoryInfo(myArmsUpdate.InstallationPath);
DirectorySecurity myDirectorySecurity = myDirRoot.GetAccessControl();
FileSystemAccessRule myPermission = new FileSystemAccessRule(userPermission , FileSystemRights.ReadAndExecute, InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit, PropagationFlags.InheritOnly, AccessControlType.Allow);

myDirectorySecurity.AddAccessRule(myPermission);
myDirRoot.SetAccessControl(myDirectorySecurity);

However I still get the same error:

System.Security.Principal.IdentityNotMappedException

Try to Run your VS ->Run as administrator. Sometimes that may fix the exception. — New Developer, Feb 08 '13 at 09:44

Try the following,

DirectorySecurity sec = Directory.GetAccessControl(path);
        // Using this instead of the "Everyone" string means we work on non-English systems.
        SecurityIdentifier everyone = new SecurityIdentifier(WellKnownSidType.WorldSid, null);
        sec.AddAccessRule(new FileSystemAccessRule(everyone, FileSystemRights.Modify | FileSystemRights.Synchronize, InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit, PropagationFlags.None, AccessControlType.Allow));
        Directory.SetAccessControl(path, sec);

Note: You must be an administrator to make this work

That code looks suspiciously like what is [found here](http://stackoverflow.com/a/5398398/109702). If you can copy code like this then the question should be closed as a duplicate. – slugster Nov 19 '14 at 02:49
