CreateDirectory执行没有抛出异常，但是也没有成功创建目录，这是为什么?


            DirectorySecurity securityRules = new DirectorySecurity();
            securityRules.AddAccessRule(new FileSystemAccessRule(@"Domain\account1", FileSystemRights.Read, AccessControlType.Allow));
            securityRules.AddAccessRule(new FileSystemAccessRule(@"Domain\account2", FileSystemRights.FullControl, AccessControlType.Allow));            DirectoryInfo di = Directory.CreateDirectory(@"C:\destination\NewDirectory", securityRules);
