Question

我不明白如何将文件中的数字与从函数传递的数字进行比较。

这是我的代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;

namespace Guess_Game
{
  class Program
  {
    static void Main(string[] args)
    {
        int quantity;
        int min, max;
        Console.WriteLine("Enter the Quantity of Numbers : ");
        quantity = int.Parse(Console.ReadLine());

        Console.WriteLine("Enter the Maximum and Minimum Number that you wish to be in your file : \n");
        Console.WriteLine("MIN : ");
        min = int.Parse(Console.ReadLine());
        Console.WriteLine("MAX : ");
        max = int.Parse(Console.ReadLine());
        Console.WriteLine("Now, Guess the Number : ");
        int number = int.Parse(Console.ReadLine());

        Console.WriteLine("Now Guess a Number That already contains in a File : ");
         number = int.Parse(Console.ReadLine());
         GuessGame(min, max, quantity, number);

        //if(number!= // number not equal to that number that contains in a file.. how to write it in that 
            //if condition..
    }

    static void GuessGame(int min,int max,int quantity,int number)
    {
        Random r = new Random();
        StreamWriter sw = new StreamWriter(@"D:\nasir\Guess Game\Guess Game\bin\Debug\ Guess Game.txt");

        for (int i = 0; i < quantity; i++)
        {
            int temp = r.Next(min, max);
            sw.WriteLine(temp);
        }
       // while(number != sw.WriteLine())
        {
            Console.WriteLine("Your Guess is Wrong!");
        }
        sw.Close();
    }
  }
}

你每次都在掷骰子（不公平，IMO）并且不会读取该文件，而只是写出来。让我们从这开始：

static void Main()
{
    Random r = new Random();
    bool lucky = false;
    int maxTries, minValue, maxValue, guess = 0;

    GetInput("Enter number of tries: ", out maxTries);
    GetInput("Enter minimum number : ", out minValue);
    GetInput("Enter maximum number : ", out maxValue);

    int magical = r.Next(minValue, maxValue); // only once
    for (int i = 1; i <= maxTries; i++)
    {
        GetInput("Enter your guess : ", out guess);
        if (guess == magical)
        {
            lucky = true;
            break;
        }
    }

    Console.WriteLine("you.Lucky = {0};", lucky);
    Console.ReadLine();
}

static void GetInput(string text, out int variable)
{
    do Console.Write(text);          // avoiding stackoverflow.com scroll
    while (!Int32.TryParse(Console.ReadLine(), out variable));
}

如果您想从文件中获取数字，请尝试以下操作：

List<int> magicals = new List<int>();
using (StreamReader reader = new StreamReader("GuessGame.txt"))
{
    int magical = 0;
    string line = "";
    while (!String.IsNullOrEmpty(line = reader.ReadLine()))
    {
        if (Int32.TryParse(line, out magical))
            magicals.Add(magical);
    }
}

并且测试是这样的：

if(magicals.Contains(guess))

我不知道你的档案是怎样的......

图像：

12
17
9

然后你使用：

string[] fileNumbers = File.ReadAllLines("C:\MyGuessNumbers.txt");

所以在fileNumbers中你将所有数字都放到一个字符串数组中，只需循环并比较：）

TRY PARSE vs PARSE

来自您的代码：

int quantity;
Console.WriteLine("Enter the Quantity of Numbers : ");
quantity = int.Parse(Console.ReadLine());

如果Console.ReadLine（）不是一个整数，你会得到一个异常，说该对象无法被解析，是写，一个“A”是一个字符串，而不是一个整数

如果您使用

int quantity = 0;
Console.WriteLine("Enter the Quantity of Numbers : ");
while(! int.TryParse(Console.ReadLine(), out quantity) )
   Console.WriteLine("That does not seam to be an integer, please only use numbers!\nEnter the Quantity of Numbers : ");

这将验证是否为数字，因为它将进行TRY解析，如果成功解析整数，它将返回布尔值TRUE或FALSE。

在这个例子中，我循环直到用户以编程语言输入数字，而TryParse返回false。

你有一个小错误，你将整数与文件编写器sw进行比较，所以猜测总是错误的。输入猜测后添加文件阅读器，以便完全关闭连接：

 sw.Close();      
 StreamReader sr = new StreamReader(@"C:Guess Game.txt");
