我想用RNGCryptoServiceProvider作为我的随机数的来源。因为它只能输出它们作为字节值数组我怎样才能将它们转换为0到1，而结果preserving一致性？

  byte []的结果=新的字节[8]。
rng.GetBytes（结果）;
返程（双）BitConverter.ToUInt64（结果，0）/ ulong.MaxValue;
 

I would like to use RNGCryptoServiceProvider as my source of random numbers. As it only can output them as an array of byte values how can I convert them to 0 to 1 double value while preserving uniformity of results?

byte[] result = new byte[8];
rng.GetBytes(result);
return (double)BitConverter.ToUInt64(result,0) / ulong.MaxValue;
