Question

我正在制作一个简单的纸张，摇滚，剪刀游戏（c＃），除了用户可以键入的部分（例如）是或否，我做了所有内容，然后再次播放或退出。我该怎么做？这是我目前的代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Do you choose rock,paper or scissors");
            string userChoice = Console.ReadLine();

            Random r = new Random();
            int computerChoice = r.Next(4);

                if (computerChoice == 1)
                {
                    if (userChoice == "rock")
                    {
                        Console.WriteLine("The computer chose rock");
                        Console.WriteLine("It is a tie ");                     
                    }
                    else if (userChoice == "paper")
                    {
                        Console.WriteLine("The computer chose paper");
                        Console.WriteLine("It is a tie ");

                    }
                    else if (userChoice == "scissors")
                    {
                        Console.WriteLine("The computer chose scissors");
                        Console.WriteLine("It is a tie ");
                    }
                    else
                    {
                        Console.WriteLine("You must choose rock,paper or scissors!");

                    }

                }

                else if (computerChoice == 2)
                {
                    if (userChoice == "rock")
                    {
                        Console.WriteLine("The computer chose paper");
                        Console.WriteLine("Sorry you lose,paper beat rock");

                    }
                    else if (userChoice == "paper")
                    {
                        Console.WriteLine("The computer chose scissors");
                        Console.WriteLine("Sorry you lose,scissors beat paper ");

                    }
                    else if (userChoice == "scissors")
                    {
                        Console.WriteLine("The computer chose rock");
                        Console.WriteLine("Sorry you lose,rock beats scissors");                       
                    }
                    else
                    {
                        Console.WriteLine("You must choose rock,paper or scissors!");        
                    }
                }
                else if (computerChoice == 3)
                {
                    if (userChoice == "rock")
                    {
                        Console.WriteLine("The computer chose scissors");
                        Console.WriteLine("You win,rock beats scissors");

                    }
                    else if (userChoice == "paper")
                    {

                        Console.WriteLine("You win,paper beats rock");

                    }

                        Console.WriteLine("You win,scissors beat paper");

                    }
                    else
                    {
                        Console.WriteLine("You must choose rock,paper or scissors!");

                    }

                }

            Console.ReadLine();
        }
    }
}

帮助！...

Answer 1

删除最后一个ReadLine，将整个逻辑放在while块中，如下所示：

bool keepPlaying = true;
while (keepPlaying) {
    //game logic here

    Console.WriteLine("New game? y/n");
    ConsoleKeyInfo cki = Console.ReadKey(); //wait for player to press a key
    keepPlaying = cki.KeyChar == 'y'; //continue only if y was pressed
}

Answer 2

您可以将所有内容包装在do while结构中：

class Program
{
    static void Main(string[] args)
    {
        do
        {
            Console.WriteLine("Do you choose rock,paper or scissors");
            string userChoice = Console.ReadLine();
            // Rest of your code
        }while(Console.ReadLine() == "yes");
    }
}

这将执行您的代码一次，然后每次用户输入yes时再次执行。

有了这个，你不需要任何私人变量，你就可以确定游戏至少会被执行一次。如果你想提示用户（单独的某些内容＆＃34;再次播放？＆＃34;），你可以在现有代码的末尾，}while部分之前完成。

Answer 3

首先，当你打电话给r.Next(4);时，程序有机会生成一个从0到3的数字。所以computerChoice的可能性是0,1,2,3 ......你的程序做了当它等于0时没有任何处理computerChoice的代码，因此它会突然关闭。要解决这个第一次更改r.Next(4);到r.Next(3);，它将提供0,1,2的可能性。只需将else if (computerChoice == 3)更改为`else if（computerChoice == 0）＆＃39;。这将修复您的程序。其次，正如其他答案所说，围绕整个程序循环是明智的，这样你就可以多次玩RPS。
