退出游戏后掷骰子游戏循环不止一次

Question

I am trying to make a program to play a game of craps where the user enters a bet amount, then they roll 2 six sided dice. If the sum of the dice s 2,3 or 12 they lose. 7 or 11 they win. if any other number is rolled the player keeps rolling until they get the point number to win or 7 to lose. However for some reason if I select n to not play again it still loops the game a second time before quitting. I am not sure why any help would be appreciated.

static void processCraps()
{
    string gameStatus = null;
    double betAmount =0;
    double netWinning = 0;
    int point;
    do
    {
        try
        {
            Console.WriteLine("Enter the amount to bet");
            betAmount = double.Parse(Console.ReadLine());
        }
        catch (Exception)
        {
            Console.WriteLine("Invaid input try again");
        }

        var diceRoll = RollDice();
        if (diceRoll == 2 || diceRoll == 3 || diceRoll == 12)
        {
            Console.WriteLine($"You lost {betAmount}");
            netWinning = netWinning - betAmount;
        }
        else if (diceRoll == 7 || diceRoll == 11)
        {
            Console.WriteLine($"You won {betAmount}");
            netWinning = netWinning + betAmount;
        }
        else if (diceRoll != 2 || diceRoll != 3 || diceRoll != 12 || diceRoll != 7 || diceRoll != 11)
        {
            point = diceRoll;
            Console.WriteLine($"Point is {point}");
            for (int rollCount = 0; rollCount >= point; rollCount++)
            {
                var roll = RollDice();
                if (roll == 7)
                {
                    Console.WriteLine($"You lost {betAmount}");
                    netWinning = netWinning - betAmount;
                }
                else if (roll == point)
                {
                    Console.WriteLine($"You won {betAmount}");
                    netWinning = netWinning + betAmount;
                }
            }
        }
        try
        {
            Console.WriteLine("Do you want to play again (y/n)");
            gameStatus = Console.ReadLine();
        }
        catch (Exception)
        {
            Console.WriteLine("answer must be a letter");
        }
    } while (gameStatus != "n") ;
    Console.WriteLine($"Your net winning is {netWinning}");
}

Answer 1

You read input twice.

You may want to split the logic into two loops. 1. Read bet amount. 2. Play game.

do 
{
    Console.WriteLine("Enter the amount to bet, or 'q' to quit:");
    var betStr = Console.ReadLine();
    if( betStr == "q") return;
    double.TryParse(betStr, out betAmount);
} while (betAmount != 0);

do
{
    //Play
    Console.WriteLine("Do you want to play again (n = quit)?");
    gameStatus = Console.ReadLine();
} while (gameStatus != "n");
