static void Main(string[] Args)

           //假设扫描C:Test中——

            string[] hiddenfiles = Directory.GetFiles("C:\Test\", "*.*", SearchOption.AllDirectories);

           
            foreach (var item in hiddenfiles)
            {
                if ((new FileInfo(item).Attributes & FileAttributes.Hidden) == FileAttributes.Hidden)   //必须进行与运算，因为默认文件是“Hidden”+归档（二进制11）。而Hidden是10.因此与运算才可以判断
                {
                    Console.WriteLine(item);
                }
            }

        }
