C#

string b1 = "+120";
byte b1b;
if (!byte.TryParse(b1, out b1b)) return;

Then use bib in your array.
Or better:

C#

string b1 = "+120";
byte b1b;
if (!byte.TryParse(b1, out b1b)) return;
sb2.AppendFormat($"-{b1b:X2}");

Assuming sb2 is a StringBuilder object and you want the hex value...

C#

sb2.AppendFormat("{0:X2}{1:X2}", b1, b2));
