Question

我正在参加和进入c＃课程并且我有很多有趣的学习，但是我不得不停留在这一项任务 - 我必须模拟滚动6面骰子/模具500次（用户必须输入卷数）显示每边的频率（1-6）和％roll。另外我不能使用数组。所以，开始我所做的是启动一个bool来循环我的代码，因为我必须询问用户是否要再次滚动。然后我为dice1创建了一个变量，并将其设置为1-6之间的随机数。我尝试将变量设置为等于dice1的控制台readline，让用户输入数字。这几乎是我陷入困境并无法前进的地方。我知道你们中许多人比我更有知识，所以如果有人能给我一些建议那就太棒了。

这是我到目前为止所拥有的：

    static void Main(string[] args)
    {
        //Initiate Looping Seqence
        bool choice = true;
        while (choice)
        {
            //Display Introduction and Instructions
            Console.WriteLine("Welcome To The Dice Game!");
            Console.WriteLine("This Program will simulate rolling a die and will track");
            Console.WriteLine("the Frequency each value is  rolled Then Display a Session Summary");
            Console.WriteLine("Press any key to continue.....");
            Console.ReadKey();
            Console.Clear();
            Console.WriteLine("How many times would you like to roll the die?");
            Random randomNum = new Random();

            int dice1;
            dice1 = randomNum.Next(1, 7);

            int choice2 = Convert.ToInt32(Console.ReadLine());

            Console.WriteLine();


            Console.WriteLine(dice1);


            int s1 = 0;
            int s2 = 0;
            int s3 = 0;
            int s4 = 0;
            int s5 = 0;
            int s6 = 0;



            Console.WriteLine("Would you Like to Run This Program Again?");
            Console.WriteLine("Type \"yes\" to re-run or Type \"no\" to exit?");
            Console.ReadKey();

            string option;
            option = Console.ReadLine();
        }
    }

      // public static double RollDice()
      //{
      // was not sure if to create a dice roll method            
      //}

    }

    }

这是一些模拟卷筒和卷筒的代码。得到弹出数字的次数

int rollAmount = 500;
int dice;
int s1 = 0;
int s2 = 0;
int s3 = 0;
int s4 = 0;
int s5 = 0;
int s6 = 0;
Random random = new Random();
for(int i = 0; i <= rollAmount; i++){
    dice = random.next(1,7);
    Console.Writeline("Roll " + i + ": " + dice.ToString());
    if(dice == 1) s1++;
    else if(dice == 2) s2++;
    else if(dice == 3) s3++;
    ...
}
Console.Writeline("1 Percentage: " + ((s1 / rollAmount) * 100) + "%");
Console.Writeline("2 Percentage: " + ((s2 / rollAmount) * 100) + "%");
Console.Writeline("3 Percentage: " + ((s3 / rollAmount) * 100) + "%");
...
Console.Writeline("Done");
