Will the following method return a correct sum of the numbers?

public int Add(string s)
{
   int result = 0;

       result += Convert.ToInt32(s[i]);

false

View Description

Convert.ToInt32(s[i]) does not convert the string at the specified index to a number. It converts the Unicode char to it's 32-bit signed integer value. To make this work, the ToInt32 method would need to be passed a string - Convert.ToInt32(s[i].ToString()).
