How to convert string of hex values into string of numbers in C#

Question

I have got the string like in hex view

33-35-34-37-36-32-31-31-32-35-32-31-32-38-38

I would like to get it like a string of corresponding values

354762112521288

I see it could be done like here

So I am wondering which methods I have to use for it?

I try this for the first value is 33

 string hex = "0x33"; 
 int intValue =  Convert.ToInt32(hex, 16);

but It gives me 51 instead of 3.

Thanks for helping!

Those are hex values of characters representing digits (byte)'3' = 0x33. To get a char from a byte value like this, do `char c = (char)byteValue`. — 500 - Internal Server Error, Apr 02 '21 at 08:53

@DmitryBoyko I think Sweeper was hoping you'd tell him which of the two alternatives he mentioned apply :) — Matthew Watson, Apr 02 '21 at 09:02
@Sweeper It is int[] containing 33, 35, 34, 37, 36, 32, 31, 31, 32, 35, 32, 31, 32 — DmitryBoyko, Apr 02 '21 at 09:05

`int[] numbers = { 33, 35, 34, 37, 36, 32, 31, 31, 32, 35, 32, 31, 32, 38, 38 }; int[] converted = numbers.Select(number => Convert.ToInt32(number.ToString(), 16) - '0').ToArray();` — Matthew Watson, Apr 02 '21 at 09:12

I think,
The hex value for 3 is "3"
"0x33" is 51 in decimal
