Console.read(); not lets me input any value and sets variable value to 13

Question

i have some execution issues, where the same function is not working in the same way

while(mano.Count != 0)    // inizio partita
            {
                int count = 0;
                scelta = Convert.ToInt32(Console.Read()) -48;
                string res = cl.Colleziona(mano[scelta - 1], ID);                    
                while (res == "Non e' il tuo turno" || res.StartsWith("Il tuo avversario ha giocato: "))
                {
                    if (res.StartsWith("Il tuo avversario ha giocato: "))
                    {
                        Console.WriteLine(res + ", seleziona di nuovo una carta: ");                           
                        scelta = Convert.ToInt32(Console.Read());  //here gives the error
                        res = cl.Colleziona(mano[scelta-1], ID);
                        Console.WriteLine(res);
                        break;
                    }
                    else if (count == 0)
                    {
                        Console.WriteLine(res);
                        count++;
                    }                        
                    System.Threading.Thread.Sleep(200);
                    res = cl.Colleziona(mano[scelta - 1], ID);
                }                    
                mano.Remove(mano[scelta-1]);
                ris = cl.partita();
                while (ris == null)
                {                      
                    System.Threading.Thread.Sleep(200);
                    ris = cl.partita();              
                }

The commented function returns 13 instead of letting me input something, giving OutOfRangeException on the successive function, any solution?

Thanks

It looks like you wanted to call Console.ReadLine. This returns the whole line as a string whereas Console.Read returns an int that represents one character at a time.

In this case, 13 represents the carriage return - you likely hit enter after typing your first bit of input.

This question covers the difference between the various Console.ReadX methods in more detail.
