如何在c#中循环一个骰子游戏

我必须制作一款玩家与店主一起玩的骰子游戏，这只是玩家与店主互动的更大程序的一部分。玩家拥有一定数量的金币，在每个回合中玩家可以赢得1.1个金币，输掉1个金币，或者平局。玩家可以选择玩还是不玩。当玩家想要再次玩游戏并且拥有至少1个金币时，我便希望循环多次，当他决定不再玩游戏时，循环便会停止。我试着搜索教程，但没有找到任何特别有用的。

Console.WriteLine("Do you want to play a game of dices with me to win some gold?");
Console.WriteLine("You can lose 1 gold or you can win 1.1 gold.");
Console.WriteLine("Wanna play? y or n");
var diceAnswer = Console.ReadLine();
switch (diceAnswer)
{
    case "y":
        Random rnd = new Random();
        int playerRoll = rnd.Next(1, 7);
        Console.WriteLine("You rolled {0}", playerRoll);
        int shopRoll = rnd.Next(1, 7);
        Console.WriteLine("I rolled {0}", shopRoll);
        if (playerRoll > shopRoll)
        {
            goldLeft += 1.1;
            Console.WriteLine("You won 1.1 gold, therefore you now have " + goldLeft + " gold");
        }
        else if (playerRoll < shopRoll)
        {
            goldLeft--;
            Console.WriteLine("You lost 1 gold, therefore you now have " + goldLeft + " gold");
        }
        else
        {
            Console.WriteLine("That is a draw. Seems that we are both lucky");
        }
        break;
    case "n":
        Console.WriteLine("That is a safe choice.");
        break;
    default :
        Console.WriteLine("Since that is not a good answer, I will not play with you");
        break;
}

如何在c#中循环一个骰子游戏

类似这样(while loop with break s):

// do not re-create Random
private static Random rnd = new Random();
...
Console.WriteLine("Do you want to play a game of dices with me to win some gold?");
Console.WriteLine("You can lose 1 gold or you can win 1.1 gold.");
while (goldLeft >= 1.0) { // you must have enough gold if you want to play 
  Console.WriteLine("Wanna play? y or n");
  string answer = Console.ReadLine();
  if (answer.Equals("n")) {
    Console.WriteLine("That is a safe choice.");
    break;
  }
  else if (!answer.Equals("y")) {
    Console.WriteLine("Since that is not a good answer, I will not play with you");
    break;
  }
  // Case "y" here
  int playerRoll = rnd.Next(1, 7);
  int shopRoll = rnd.Next(1, 7);  
  if (playerRoll > shopRoll) {
    goldLeft += 1.1;
    Console.WriteLine("You won 1.1 gold, therefore you now have " + goldLeft + " gold");
  }
  else if (playerRoll < shopRoll) {
    goldLeft -= 1.0;
    Console.WriteLine("You lost 1 gold, therefore you now have " + goldLeft + " gold");
  }
  else {
    Console.WriteLine("That is a draw. Seems that we are both lucky");
  }  
}

你可以使用do-while循环总是在第一次运行，但如果玩家决定不继续这样做，则在结束时中断:

bool keepPlaying = true;
do {
    Console.WriteLine("Do you want to play a game of dices with me to win some gold?");
    Console.WriteLine("You can lose 1 gold or you can win 1.1 gold.");
    Console.WriteLine("Wanna play? y or n");
    var diceAnswer = Console.ReadLine();
    switch (diceAnswer)
    {
        case "y":
            keepPlaying = true;
            Random rnd = new Random();
            int playerRoll = rnd.Next(1, 7);
            Console.WriteLine("You rolled {0}", playerRoll);
            int shopRoll = rnd.Next(1, 7);
            Console.WriteLine("I rolled {0}", shopRoll);
            if (playerRoll > shopRoll)
            {
                goldLeft += 1.1;
                Console.WriteLine("You won 1.1 gold, therefore you now have " + goldLeft + " gold");
            }
            else if (playerRoll < shopRoll)
            {
                goldLeft--;
                Console.WriteLine("You lost 1 gold, therefore you now have " + goldLeft + " gold");
            }
            else
            {
                Console.WriteLine("That is a draw. Seems that we are both lucky");
            }
            break;
        case "n":
            keepPlaying = false;
            Console.WriteLine("That is a safe choice.");
            break;
        default :
            keepPlaying = false;
            Console.WriteLine("Since that is not a good answer, I will not play with you");
            break;
    }
} while (keepPlaying);

您可以在这里了解更多关于do-while循环的信息，但原则上，do块的内容至少执行一次，并且在while语句末尾的条件语句求值为true时重新执行。
