[C#]解决多语言操作系统找不到everyone NTAccount问题

NTAccount acct = new NTAccount("Everyone");
FileSystemAccessRule allowRule = new FileSystemAccessRule(acct, FileSystemRights.FullControl,
InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit,
PropagationFlags.None, AccessControlType.Allow);

这两行代码运行在英文系统下一切正常，但如果在多语言（如葡萄牙、瑞典、芬兰）系统下则会引发异常，异常信息如：

The conversion of some or all identifying references has failed或

Some or all identity references could not be translated.

也就是在多语言系统找不到对应的“Everyone” NTAccount，那问题自然就转移到如何才能在多语言系统找到匹配的“everyone”呢？这得感谢该帖子：http://social.msdn.microsoft.com/forums/en-US/netfxbcl/thread/0737f978-a998-453d-9a6a-c348285d7ea3/

直接找到答案了，代码调整如下：

SecurityIdentifier sid = new SecurityIdentifier(WellKnownSidType.WorldSid, null);
NTAccount acct = sid.Translate(typeof(NTAccount)) as NTAccount;

FileSystemAccessRule allowRule = new FileSystemAccessRule(acct, FileSystemRights.FullControl,
InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit,
PropagationFlags.None, AccessControlType.Allow);

WellKnownSidType.WorldSid的Summary是：Indicates a SID that matches everyone.
