How to convert an int to a little endian byte array?

Question

I have this function in C# to convert a little endian byte array to an integer number:

int LE2INT(byte[] data)
{
  return (data[3] << 24) | (data[2] &l         


        

Answer 1

 public static string decimalToHexLittleEndian(int _iValue, int _iBytes)
    {
        string sBigEndian = String.Format("{0:x" + (2 * _iBytes).ToString() + "}", _iValue);
        string sLittleEndian = "";

        for (int i = _iBytes - 1; i >= 0; i--)
        {
            sLittleEndian += sBigEndian.Substring(i * 2, 2);
        }

        return sLittleEndian;
    }
