我的程序中集成循环出现问题

问题描述

我对OO编程还很陌生，我创建了一个简单的猜数字"游戏，它可以正常运行.但是，尝试实现循环时会发生错误.更具体地说，我希望用户通过控制台重新启动程序(而不是再次编译并运行游戏).

I am fairly new to OO programming, I have created a simple "Guess the number" game, it functions correctly. However, when attempting to implement a loop errors occur. More specifically, I want the user to restart the program through a console [not compiling and running the game again].

我需要有关静态void ExitGame()方法的帮助.此时，我正在研究"RepL.it"，并且产生的错误如下:

I need help with the static void ExitGame() method. At this moment in time, I am working on "RepL.it" and the generated errors are as followed:

main.cs(10,10):警告CS0649:字段GuessTheNumber.Game.replay' is never assigned to, and will always have its default value null'编译成功-1个警告欢迎来到猜谜游戏.请按Enter.

main.cs (10,10): warning CS0649: Field GuessTheNumber.Game.replay' is never assigned to, and will always have its default valuenull'Compilation succeeded - 1 warning (s)Welcome to the guessing game. Please press enter.

using System;

namespace GuessTheNumber
{
  class Game
  {

  static int UserGuess;
  static int Answer;
  string replay;
  static string EndProg = "No";

    static void Main (string[] args)
    {
      Console.Title = "Guess the number.";

      EntryMessage();
      GenerateRandom();

      while (EndProg == "No") {
        askData();
      }
    }

    static void EntryMessage()
    {
      Console.WriteLine("Welcome to the guessing game. Please press enter.");
      Console.ReadLine();
    }

    public static void askData()
    {
      while (EndProg == "No")
      {
        Console.WriteLine(Answer);
        Console.WriteLine("Guess a number between 1 and 100.");
        UserGuess = Convert.ToInt32(Console.ReadLine());
        WinLose();
      }
      askData();
    }

    public void askData(bool endProg)
    {
      Console.WriteLine("Does you want to play again");
      if (replay == "y")//; Remove this semicolon
      {
      Console.WriteLine("\nOkay, guess again");
      askData(EndProg == "No");
      }
      else if (replay == "n")//; Remove this semicolon
      {
        askData(EndProg == "Yes");
      }
      else
      {
        Console.ReadLine();
      }
    }

    static void GenerateRandom()
    {
      Random random = new Random();
      Answer = random.Next(0,101);
    }
      static void WinLose()
      {
        if (UserGuess == Answer)
        {
          Console.WriteLine("Correct number!");
          EndProg="Yes";
        }
        else if (UserGuess > Answer)
        {
          Console.WriteLine("Too high.");
          EndProg="No";
        }
        else if (UserGuess < Answer)
        {
          Console.WriteLine("Too Low.");
          EndProg="No";
        }
        else
        {
          Console.WriteLine("Invalid answer.");
          EndProg="No";
        }
      }
  }
}

推荐答案

您的代码中存在许多语法错误:

There's a number of syntactical errors in your code:

1. 如果语句括号不应以分号后缀

1. If statement parentheses shouldn't be suffixed with a semicolon

else if (replay == "n");

应该是

else if (replay == "n")

您的askData()方法有时会被带一个布尔参数调用，但不需要一个

Your askData() method is sometimes being called with a bool argument but doesn't take one

void askData()

应该是

void askData(bool endProg)

您正在混合和匹配静态和非静态方法，需要确定是在静态还是实例上下文中实现此逻辑

You are mixing and matching static and non-static methods and need to decide whether to implement this logic in a static or instance context
