这是我用的，希望能帮到你

程序代码：

/// <summary>
        /// 字符串转16进制字节数组
        /// </summary>
        /// <param name="hexString"></param>
        /// <returns></returns>
       public static byte[] strToHexByte(string hexString)
        {
            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;
        }
