C#加密生成16位随机数

class Program
    {
        static void Main(string[] args)
        {
            string path = @"C:\AAAA16.txt";
            RandomNumberGenerator randgen = new RNGCryptoServiceProvider();
            byte[] data = new byte[8];
            using (StreamWriter sw = new StreamWriter(path, true))
            {
                for (int i = 0; i < 1000; i++)
                {
                    randgen.GetBytes(data);
                    sw.Write(Math.Abs(BitConverter.ToInt64(data, 0)).ToString().Substring(0, 16) + "  ");
                }
            }         
            Console.ReadLine();
        }
    }
