Converting a value to Hexadecimal and Decimal

Question

I have this value 10732 I converted this value to ´hexadecimal` like this:

string hex = string.Join(string.Empty, "10732".Select(c => ((int)c).ToString("X")));

And I got as result: 3130373332

But, using the Calculator of W7 in "programmer" mode. When I convert 10732from DECIMAL to HEX,
I got 29EC as result. Why ? How may I do this using C#?

There's a pretty big difference between converting a string an an int to hexadecimal. The c# does it for the string, the calculator for the int. Which one do you want ? — C4stor, Jun 19 '13 at 12:45

You are converting figure by figure. That is not how you convert int to hex — Emond Erno, Jun 19 '13 at 12:46
@C4stor So what I was doing was convert each CHAR of my string to hex ? how may I get the `29EC` ? — PlayHardGoPro, Jun 19 '13 at 12:46

You are converting each character in the string to a hex.

Char   Int value (dec)   Hex value
1      49                31
0      48                30
7      55                37
3      51                33
2      50                32

You should be simply converting the int directly:

10732.ToString("X")

If the value is a string, convert to an integer first:

Int.Parse("10732").ToString("X")

+1 For the OPs clarity string -> int -> hex would simply be `(int.Parse("10732")).ToString("X");` – NominSim Jun 19 '13 at 12:47
+1 thanks for the explanation. – PlayHardGoPro Jun 19 '13 at 12:51
Oded, is there a way to do this working with doubles? Like, If I want to get the int value of R$ `107.32` ? – PlayHardGoPro Jun 19 '13 at 12:54
@PlayHardGoPro - cast to `int`. You will get `107`. – Oded Jun 19 '13 at 12:55
