Answer 1

char '1' is 49

When you tried to convert 1 into an integer you produced the ascii result

Answer 2

b[ 1 ] gives you a `char`. When a `char` is converted to `int`, the ASCII code is used as value in calculation.

To get 1 you can subtract by char '0' (represents ASCII value 48).

int g = Convert.ToInt32( b[ 1 ] - '0' );
