This question is old but I was looking for the same thing and found a solution:

var dirSecurity = dirInfo.GetAccessControl();

// Add the DirectorySystemAccessRule to the security settings. 
dirSecurity.AddAccessRule(new FileSystemAccessRule(
    account,

    PropagationFlags.None, 
    AccessControlType.Allow));

// Set the new access settings.
dirInfo.SetAccessControl(dirSecurity);
