Convert hex string to byte array

I’ve an string like this:
“021500010000146DE6D800000000000000003801030E9738”

What I need is the following byte array:
02 15 00 01 00 00 14 6D E6 D8 00 00 00 00 00 00 00 00 38 01 03 0E 97 38 (each pair of number is the hexadecimal value in the respective byte).

Any idea about how can I make this conversion?? Thanks!!

Answer 1

var arr = new byte[s.Length/2];
for ( var i = 0 ; i<arr.Length ; i++ )
    arr[i] = (byte)Convert.ToInt32(s.SubString(i*2,2), 16);
