    Tic Tac Toe

    hey..im creating a simple tic tac toe game in c# but im having a small problem. i want the input to be only be accepted if it is between 0 and 8..otherwise ask the user for input again..but i cant seem to get it..here is what i have

    Code:
     static int getInput()
            {
               int input;
                Console.WriteLine("Please Make Your Move!");
                input = Convert.ToInt32(Console.ReadLine());
                if(input < 0 || input > 8)
                {
                   Console.WriteLine("Invalid Input!");
                    getInput();
                  } 
               return input;
            }
    
    while(!player1.isEmpty(value=getInput())) // check if spot has already been filled
                    {
                       Console.WriteLine("Sorry,Alredy Filled!");
                    }
                    
                    player1.makeMove(value);
    my code does the check fine..but after that if i return a value between 0 and 8..it crashes ??

    You're not doing anything with the return value from the recursive call to getInput().

    Code:
    if(input < 0 || input > 8)
    {
       Console.WriteLine("Invalid Input!");
       return getInput();
    }
