字节转换问题-0,0,0,127

问题描述

我正在尝试将字节数组转换为可读格式(第二列是时间，但不必强制转换为时间，可以强制转换为字符串)，我期望的是一个系列零，如下表所示，代表午夜.
日期....时间...........打开........等
10/07/2010 23:00:000 1.39330 1.39480 1.39090 1.39330 67817
10/08/2010 0:00:000 1.39330 1.39340 1.39020 1.39120 34728
10/08/2010 1:00:000 1.39130 1.39210 1.38490 1.38780 40004

同一列中其他数字的字节数组可以很好地转换.
例如:

Hi,
I''m trying to convert a byte array across to a readable format (the 2nd column is time but does not have to be cast as time, it could be a cast as a string), what I''m expecting is a series of zero''s like in the table below, which would represent midnight.
Date.........Time...........Open........etc
10/07/2010 23:00:000 1.39330 1.39480 1.39090 1.39330 67817
10/08/2010 0:00:000 1.39330 1.39340 1.39020 1.39120 34728
10/08/2010 1:00:000 1.39130 1.39210 1.38490 1.38780 40004

The byte array for the other numbers in the same column convert over fine.
For example:

byte[] bytes = { 0, 156, 96, 72 };
float Time = System.BitConverter.ToSingle(single, 0);

可以理解为230000.0(第二行的第一行)，可以根据需要解析为一个时间.其他人也都工作正常.但是午夜

Works out as 230000.0 (top line 2nd column) which I can make sense of and parse out as a time if I need to. The others all work fine too. But midnight

byte[] bytes = { 0, 0, 0, 127 };
float Time = System.BitConverter.ToSingle(single, 0)

返回 1.70141183E + 38 这不是我期望的.:confused:

任何帮助将不胜感激.

returns 1.70141183E+38 which is not what I expect.:confused:

Any help would be greatly appreciated.

推荐答案

class Program {
  static void Main(string[] args) {
    ShowBytes(0.0F);
    ShowBytes(1.70141183E+38F);
  }

  private static void ShowBytes(Single s) {
    Byte[] b = BitConverter.GetBytes(s);
    Console.WriteLine("{0} {{ {1}, {2}, {3}, {4} }}", s, b[0], b[1], b[2], b[3]);
  }

输出为

Output is

<pre>0 { 0, 0, 0, 0 }
1.701412E+38 { 0, 0, 0, 127 }

Alan.

private float GetFloat()
{
byte[] bytes = { 0, 0, 0, 127 }
if (bytes[3] == 0) return 0.0f;

* code here*.
}

对于任何分钟数，这实际上将返回0.

This effectively returns 0 for any minute number.
