Well, since this *has* become a HomeWork Help Forum, here goes :
Calculate("1701209041");
private void Calculate(string s)
{
try
{
char[] cDigits = s.ToCharArray();
int[] digits = Array.ConvertAll<char, int>(cDigits, new
Converter<char, int>(ConvertCharToInt));
double calculo;
calculo = (digits[0] * 3) + (digits[1] * 2) + ... ;
}
catch(FormatException fe)
{
// Handle the exception.
}
}
private int ConvertCharToInt(char c)
{
return int.Parse(c.ToString());
}
