To convert a hexadecimal string to a number Use the ToInt32 (String, Int32) method to convert the number expressed in base-16 to an integer. The first argument of the ToInt32 (String, Int32) method is the string to convert. The second argument describes what base the number is expressed in; hexadecimal is base 16.

The question is not clear, because "hex" is very ambiguous. Please put a typical string inside the string control and make it the default, resave, and attach once more. Then tell us what result you expect. How many bytes are in the string? If it is one byte of a binary string, typecast it to U8. (It would be silly to go to a byte array)

Convert a hexadecimal string to a float. Convert a byte array to a hexadecimal string. Example. This example outputs the hexadecimal value of each character in a string. First it parses the string to an array of characters. Then it calls ToInt32(Char) on each character to obtain its numeric value. Finally, it formats the number as its

If it's missing it will still translate a hex string to a number. You can also use oct to translate binary, octal or hex strings to numbers based on the prefix: 0b - binary 0 - octal

  • How does this matter? You need the hex representation only for printing. A number is a number; decimal, binary and hex are just representations to the outside world.
  • Why does the title say "string to number" when "number to hex string" is really what you want?
  • Strange. print hex_no should NOT print quotes. Can you check that again?
  • It doesn't always represent hex as string, it's a meaningless question. There's no such thing as a a hex integer or a decimal integer - it's all binary inside the computer in any case. When you convert an integer into its hexadecimal string representation (which was what hex does) then of course you get a string...
  • there's no such thing as a "hexadecimal number". There are integers (which don't have any radix) and the string representations of integers (which can be hex, decimal, binary or something else). You can't do arithmetic directly on strings. So it's not a "workaround" to convert them to the integer, it's the correct way of doing it.
  • +1. Question is not clear. But this is a good answer if the OP is trying to read an integer from the hex string.
  • I want to get a hexadecimal value out of string formatted hexadecimal. ex. '0x16' i want it as 0x16
  • 0x16 doesn't exist in a running program! It is either '0x16' or 22 (= int('0x16', 16)).
  • +1. print doesn't add quotes. Perhaps the OP is typing hex_no and hitting enter?
