Hex String into number
-
I felt bad about giving a bad answer, so I wrote a whole program to do this. Hope this helps... Sorry I was too lazy to comment the code.
using System;
using System.Collections.Generic;
using System.Text;namespace ReverseHex
{
class Program
{
static void Main(string[] args)
{
string hexValue = Console.ReadLine();int finalNumber = 0; int multiplyCount = 0; for (int x = hexValue.Length - 1; x >= 0; x--) { int tempAdd = multiplyCount \* 15; switch (hexValue\[x\]) { case '1': finalNumber += tempAdd + 1; break; case '2': finalNumber += tempAdd + 2; break; case '3': finalNumber += tempAdd + 3; break; case '4': finalNumber += tempAdd + 4; break; case '5': finalNumber += tempAdd + 5; break; case '6': finalNumber += tempAdd + 6; break; case '7': finalNumber += tempAdd + 7; break; case '8': finalNumber += tempAdd + 8; break; case '9': finalNumber += tempAdd + 9; break; case 'A': case 'a': finalNumber += tempAdd + 10; break; case 'B': case 'b': finalNumber += tempAdd + 11; break; case 'C': case 'c': finalNumber += tempAdd + 12; break; case 'D': case 'd': finalNumber += tempAdd + 13; break; case 'E': case 'e': finalNumber += tempAdd + 14; break; case 'F': case 'f': finalNumber += tempAdd + 15; br -

Dude, this is a coding horror! ;P Go improve it now!!! Surely you can spot the pattern :)

Its already bad enough that I did his homework for him... I don't want to make it too nice! Hogan
Whew!

Hello I have one question regading the conversion of Hex String into Decimal number. Hex Number is in format “aaaaaa” This 24-bit field is the direction “A” counter stored LS-byte first. Example is, take this hex string "100000" which is decimal equivalent is 16 But i don't know how to convert this number into decimal number. If i give this number to C# function it is not giving me the exact 16 equivalent. Another exanples are 060100= 262 1C0000= 28 Can any body please help me how to convert these numbers into decimal equivalent using C# Thanks Shailesh
Hi, this would be my approach in pseudo-code:
int result=0;
while(stringLength!=0) {
int oneByte=0;
int.TryParse(rightmost2characters, hexSpecifier, out=oneByte);
result=(result<<8)+oneByye;
drop2charsFromString;
}:)

I'd convert the hex digits into a byte array, figure out what your target Type is, pad/swap as necessary. 24 bit types are a curse on the land handed down from angry gods to punish us for the sins of BIT-BANGERS.... sorry.... X|
class Program { static void Main(string[] args) { String s = "100000"; Byte[] temp = new Byte[4]; // int needs 4 bytes Array.Copy(GetBytes(s), 0, temp, 0, 3); // copy in the byte converted string Int32 value = BitConverter.ToInt32(temp, 0); // use BitConverter to change Console.WriteLine(value.ToString()); // format Console.ReadLine(); // wait for non-google searching OP to push something } public static byte[] GetBytes(string hexFormat) { int byteLength = hexFormat.Length / 2; byte[] bytes = new byte[byteLength]; for (int i = 0; i < byteLength; i++) { bytes[i] = AsciiAsHexToByte(new String(new Char[] { hexFormat[i * 2], hexFormat[i * 2 + 1] })); } return bytes; } public static byte AsciiAsHexToByte(string hex) { return byte.Parse(hex, NumberStyles.HexNumber, NumberFormatInfo.CurrentInfo); } }
As you can see, it's a pain to do the conversion. Scott P“It is practically impossible to teach good programming to students that have had a prior exposure to BASIC: as potential programmers they are mentally mutilated beyond hope of regeneration.” -Edsger Dijkstra

I'll 1/2 do your homework for ya ;)
Imports System
Imports System.Globalization
Imports System.TextModule Module1
Sub Main()
Dim sb As New StringBuilder("1C0000")
Dim str As String
Dim value As Integer
Dim bval As Byte
Dim j As DoubleIf (sb.Length Mod 2) = 1 Then sb.Append("0") End If str = sb.ToString() For i As Integer = 1 To str.Length Step 2 j = Math.Pow(16, Convert.ToDouble(i - 1)) bval = Byte.Parse(Mid(str, i, 2), NumberStyles.HexNumber, NumberFormatInfo.CurrentInfo) value += Convert.ToInt32(Convert.ToDouble(bval) \* j) Next Console.WriteLine("The string {0} is equal to {1}", sb.ToString(), value) End SubEnd Module
:laugh: (doh! fixed logic typo)

What's the other half? Converting it to C#? ;)
I dislike the black-and-white voting system on questions/answers.
I agree that it's less nuanced, but on the other hand I see a huge increase in the usage of the voting system. It doesn't matter how good a system is, if noone uses it. :)
Despite everything, the person most likely to be fooling you next is yourself.

You are correct sir! :D There are a few other "optimizations" to be done which I would assume would garner a better grade from the original...

aye, but I think the giant images is what made people start clicking it over the little "Rate this message: {thumb down vote 1} 1 2 3 4 5 {thumb up vote 5}"
