Hex to Decimal of AutoIt is Different with C#

[Colduction]

Hi AutoIt programmers, excuse me for bothering you with multiple topics.

In AutoIt we can use Number() function to convert Hex string to number but it's output is different of C# output & and i wanna make it's output like AutoIt code.

For e.g I use this in AutoIt:

Local $dBinary = Binary("Hello") ; Create binary data from a string.
Local $dExtract = Number(BinaryMid($dBinary, 1, 5))
ConsoleWrite($dExtract & @CRLF)

And i use this for C#:

using System;
using System.Text;

//NameSpace Is Use of Project Name 
namespace TEST
{
    class Program
    {
        public static void Main(string[] args)
        {
            //declaring a variable and assigning hex value
            string dd = ToHex("Hello", Encoding.ASCII);
            decimal d = Int64.Parse(dd, System.Globalization.NumberStyles.HexNumber);

            Console.WriteLine("Result: " + d);
            //hit ENTER to exit
            Console.ReadLine();
        }

        public static string ToHex(string sInput, Encoding oEncoding, bool b0x_Prefix = false)
        {
            byte[] a_binaryOutput = oEncoding.GetBytes(sInput);
            string sOutput = BitConverter.ToString(a_binaryOutput).Replace("-", "");

            if (b0x_Prefix == false)
            {
                return sOutput;
            }
            else
            {
                return "0x" + sOutput;
            }
        }
    }
}

I say once again that excuse me for creating new topic, in fact i'm making a library for GAuthOTP from a topic in AutoIt.

Colduction,

I believe you should be using Dec and not Number:

$dBinary = Binary("Hello")
ConsoleWrite($dBinary & @CRLF)

$dExtract_1 = Number(BinaryMid($dBinary, 1, 5))
ConsoleWrite($dExtract_1 & @CRLF)

$dExtract_2 = Dec(StringTrimLeft($dBinary, 2))
ConsoleWrite($dExtract_2 & @CRLF)

ConsoleWrite("0x" & Hex($dExtract_1, 10) & @CRLF)
ConsoleWrite("0x" & Hex($dExtract_2, 10) & @CRLF)

As you can see, using Dec allows you to recreate the original string:

0x48656C6C6F
478560413000
310939249775
0x6F6C6C6548
0x48656C6C6F

Does the Dec value match the C# output?

@Melba23 this line is what i want to tranform to C# code, but the out put of C# code is different (I've mentioned the C# code above)

In fact, i'm transforming:

to C#, because i think it's more optimized than other libs in Nuget, anyway i wanna do excersice
