I want to convert a string of hex characters (2 hex chars = 1 byte), to ASCII. Hex chars include zeros (0x00) as well, which I want to include in ASCII string.

hex string: 5000005355....
ASCII: P<null><null>SU ...

I can do it and the string length also includes nulls but when I concatenate other string, it doesn't show as its part.


Code:
string HexValue = "500000535500";
...
