Question

我知道这个问题之前已经发布了，我现在正在使用一些给我的代码但是在添加了一些东西后，我遇到了让它实际输出我想要的问题。

这就是我的控制台上出现的内容

我在做什么不会导致程序进入游戏？

using System;

class rockpsV2
{

public static void Main(string[]args)
{
   do
   {
       Console.WriteLine("Do you want to play 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")

Answer 1

问题是：Console.WriteLine("Do you want to play rock,paper or scissors?");（请注意单词＆＃39;或＆＃39;，您在问题中将其写为＆＃39;以及＆＃39;）您使用摇滚，纸张或其他方式回答该问题剪刀，如果你给出一个不同的答案，它就不会播放并进入while(Console.ReadLine() == "yes");线，如果你回答的不同于“是”和“＃39;在这里，它将离开do..while循环并退出程序

Answer 2

我会以这种方式重构整个程序

using System;

class rockpsV2
{

public static string[] choices = new string[]  { "rock", "paper", "scissor" };
public static int comparePlay(string player1, string player2) 
{
    if (player1 == player2)
        return  0;

    if (player1 == "rock" && player2 == "scissor" ||
        player1 == "paper" && player2 == "rock" ||
        player1 == "scissor" && player2 == "paper")
        return -1;

    return 1;
}


public static bool validChoice(string choice) 
{
    return choice == "rock" 
            || choice == "scissor"
            || choice == "paper";

}

public static void Main(string[] args)
{

    string userChoice = "";
   do
   {
       do {
        Console.WriteLine("Do you want to play rock,paper or scissors?");
        userChoice = Console.ReadLine();       

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

       }
       while(!validChoice(userChoice));


        Random r = new Random();
        int computerChoiceRand = r.Next(100) % 3;
        string computerChoice = choices[computerChoiceRand];

        Console.WriteLine("The computer chose {0}", computerChoice);

        int whoWins = comparePlay(computerChoice, userChoice);

        if (whoWins < 0) {
            Console.WriteLine("Sorry you lose, {0} beats {1}", computerChoice, userChoice);
        }

        if (whoWins == 0) {
            Console.WriteLine("It is a tie");
        }

        if (whoWins > 0) {
            Console.WriteLine("You win,{0} beats {1}", userChoice, computerChoice);
        }

        Console.WriteLine("Want to play again?");
        } while(Console.ReadLine() == "yes");
    }
}
