C#操作Byte数组和十六进制进行互转

一、Byte 数组转十六进制字符串

 		/// <summary>
        /// Byte 数组转十六进制字符串
        /// </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、字符串转十六进制Byte数组

        /// <summary>
        /// 字符串转十六进制Byte数组
        /// </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;
            }

        }
