一、Byte 陣列轉十六進位制字串

 		/// <summary>
        /// Byte 陣列轉十六進位制字串
        /// </summary>
        /// <param name="Bytes"></param>
        /// <returns></returns>
        public static string ByteToHex(byte[] Bytes)
        {
            string str = string.Empty;
            foreach (byte Byte in Bytes)
            {
                str += String.Format("{0:X2}", Byte) + " ";
            }
            return str.Trim();
        }
      
 

二、字串轉十六進位制Byte陣列

        /// <summary>
        /// 字串轉十六進位制Byte陣列
        /// </summary>
        /// <param name="hexString"></param>
        /// <returns></returns>
        public static byte[] strToToHexByte(string hexString)
        {
            try
            {
                hexString = hexString.Replace(" ", "");
                if ((hexString.Length % 2) != 0)
                    hexString += " ";
                byte[] returnBytes = new byte[hexString.Length / 2];
                for (int i = 0; i < returnBytes.Length; i++)
                    returnBytes[i] = Convert.ToByte(hexString.Substring(i * 2, 2), 16);
                return returnBytes;
            }
            catch
            {
                return null;
            }

        }
