c# - Reading from file with different line length

Question

does anyone know how to read from file to array(container with inheritance) when the line length is different?(I hope language barrier won't make any problems:))

 Sportas Skaitymas(Sportas sportas)
        {
            SportininkasCointainer sportininkai = new SportininkasCointainer();
            KomandaContainer komandos = new KomandaContainer();

            using (StreamReader reader = new StreamReader("Duomenys.txt"))
            {
                string line = null;
                while ((line = reader.ReadLine()) != null)
                {
                    string[] values;

                    values = line.Split(';');                    
                    string a = values[0];
                    string b = values[1];
                    string c = values[2];
                    string d = values[3];
                    string e = values[4];
                    string f = values[5];
                    string g = values[6];

                    switch (values.Length)
                    {
                        case 7:
                            Krepsininkas krepsininkas = new Krepsininkas(a, b, c, int.Parse(d), int.Parse(e), int.Parse(f), int.Parse(g));
                            sportininkai.AddSportinkas(krepsininkas as Krepsininkas);
                            break;

                        case 6:
                            Futbolininkas futbolininkas = new Futbolininkas(a, b, c, int.Parse(d), int.Parse(e), int.Parse(f));
                            sportininkai.AddSportinkas(futbolininkas as Futbolininkas);
                            break;

                        case 4:
                            Komanda komanda = new Komanda(a, b, c, int.Parse(d));
                            komandos.AddKomanda(komanda);
                            break;
                    }  
                }
            return sportas;
    }

I would be very grateful :)

You can use:

string a = values.Length > 0 ? values[0] : "";
string b = values.Length > 1 ? values[1] : "";

Here, string is only set when value is present else it will be ""
