I am trying to convert Binary string to hex, however I miss the zero values, I mean Binary string 000001010100 should become hex string 054?
I'm currently using
Convert.ToInt32(value,2).ToString("X")

Can you show the code you're currently using to do the conversion?hatchet - done with SOverflow– hatchet - done with SOverflow2014-06-12 22:29:51 +00:00Commented Jun 12, 2014 at 22:29

You can simply use
Convert.ToInt32(value,2).ToString("X3")
where the number following the X is the minimum number of digits you want in the final string. I used the number 3, because that was the output you included as an example. It's explained in more detail in this Microsoft documentation.

+1. fine for small numbers. Consider
"x"+(value.Length / 4) as format if need to handle 1-4 hex digits.You can split the string in four digit parts, parse them and format into a hex digit. That gives you the correct number of digits. Example:
string bin = "000001010100";
string hex = String.Concat(
Regex.Matches(bin, "....").Cast<Match>()
.Select(m => Convert.ToInt32(m.Value, 2)
.ToString("x1"))
);

+1. Handles arbitrary length of strings as long it is aligned to 4 bits. If need to also handle non-aligned strings consider
for loop and cut out sub-strings instead of Regex.
