Question

I really don’t know what is going on. It worked the first time, then when I try to do the second time it fails

I already checked spelling and found nothing. I am lost without help

I pointed out with a //comment the error line 🙂

Just in case my code is not self-explanatory, I want to get the second digit using the [1] selector

My code is:

    static void Main(string[] args)
    {
        españolizar("55","44");
    }
    static void españolizar(string str, string str2)
    {
        string[] list1={"cero","un","dos","tres","cuatro","cinco","seis","siete","ocho","nueve","diez","once","doce","trece","catorce","quince"};
        string[] list2={"nivelarindexes","dieci","veinti","trei","cuare","cincue","sese","sete","oche","nove"};

        int numero = int.Parse(str);
        string strNumero = Convert.ToString(numero);


        int primerDigito = int.Parse(Convert.ToString(strNumero[0]));
        int segundoDigito = 0;

        if (strNumero.Length > 1)
            //this is the one that fails
            segundoDigito = int.Parse(Convert.ToString(strNumero[1]));
            //\-------------------------/
        }

        Console.WriteLine(strNumero);
        Console.ReadLine();
    }

Answer 1

if (strNumero.Length > 1)
{ //ADD THIS!!!!
  segundoDigito = int.Parse(Convert.ToString(strNumero[1]));
}

You forgot to open braces.
