在c＃中将字节数组转换为整数 [英] convert byte array to integer in c#

问题描述

float input = 25;
            byte[] buffer = BitConverter.GetBytes(input);

缓冲区包含0x00 0x00 0xc8 0x41。我需要将它转换回浮点数，即25.我只知道十六进制值，请告诉我怎么做。

buffer contains 0x00 0x00 0xc8 0x41.I need to convert it back to float i.e 25.I knows only hex values,Please tell how to do it.

推荐答案

BitConverter.ToSingle [ ^ ]方法？



eg

What's wrong with BitConverter.ToSingle[^] method?

e.g.

float input = 25;
byte[] buffer = BitConverter.GetBytes(input);
float output = BitConverter.ToSingle(buffer,0);

private Single ConvertHexToSingle(string hexVal)
       {

           try
           {

               int i = 0, j = 0;

               byte[] bArray = new byte[4];

               for (i = 0; i <= hexVal.Length - 1; i += 2)
               {

                   bArray[j] = Byte.Parse(hexVal[i].ToString() + hexVal[i + 1].ToString(), System.Globalization.NumberStyles.HexNumber);

                   j += 1;

               }

               Array.Reverse(bArray);

               Single s = BitConverter.ToSingle(bArray, 0);

               return (s);

           }
           catch (Exception ex)
           {

               throw new FormatException("The supplied hex value is either empty or in an incorrect format.  Use the " +

                   "following format: 00000000", ex);
