[SOLVED]Why is converting from string not working?

Question

The input is '371' and the piece of code is:

string x = Console.ReadLine();
int a = Convert.ToInt32(x[0]);

Console.WriteLine(a);

It then outputs 51, why isn't it 3 as the 1st character of the string?

Answer 1

You are accessing a character of a string via it's index position.
A character is converted to it's ASCII counterpart via ToInt32().

Instead, you may do:

int a = Convert.ToInt32(new string(x[0],1));
