所以我在这里得到了以下代码......我必须提供 5 个用户提供的单词，在 5 个上随机化并给出其中任何一个以供猜测，tries = word length + 2. 我遇到的主要问题是循环整个检查以填写第二个、第三个猜测等。第一个猜测很好。我将如何循环并保持正确猜测的字符，同时仍将未猜测的字符保留为“_”字符。

示例 -Word was "Heaven" - User Enters "e" - Produces - _ e _ _ e _ 没有空格。然后尝试将等于 6（字长）+ 2 = 8 次尝试

int tries = 0;
Random rand = new Random();
int randomword = rand.Next(1, 5);
string word = "";

Console.WriteLine("Please Enter 5 Words into the System");
Console.WriteLine();

for (int i = 0; i < 5; i++)
{
    words.Add(Console.ReadLine());
    Console.Clear();
}

Console.WriteLine("For Display Purposes. Here are Your 5 Words");
Console.WriteLine("===========================================");
Console.WriteLine();
foreach (var item in words)
{
    Console.WriteLine(item);
}

Console.WriteLine();
Console.WriteLine("Now Guess The word given Below");
Console.WriteLine();

switch (randomword)
{
    case 1:
        //Gets the List index 0 - 1st word in the list
        word = words[0];
        tries = word.Length;
        break;
    case 2:
        word = words[1];
        tries = word.Length;
        break;
    case 3:
        word = words[2];
        tries = word.Length;
        break;
    case 4:
        word = words[3];
        tries = word.Length;
        break;
    case 5:
        word = words[4];
        tries = word.Length;
        break;
    default:
        break;
}
//Default + addition to the Length
tries += 2;

Console.WriteLine();
Console.WriteLine("You Have {0} + tries",tries );
//Works for the 1st Guess
do
{
    char guess = char.Parse(Console.ReadLine());
    if (word.Contains(guess))
    {
        foreach (char item in word)
        {
            if (item == guess)
            {
                Console.Write(item);
            }
            else
            {
                Console.Write("_");
            }
        }
    }
    Console.WriteLine();
} 
//If my word contains A "_" i will keep looping
while (word.Contains("_"));

Console.ReadKey();

您需要存储猜测结果并检查您的循环（将do while循环更改为如下）：

string resultword = word;
do
{
    char guess = char.Parse(Console.ReadLine());


    if (word.Contains(guess))
    {
        resultword = resultword.Replace(guess, ' ');

        for (int i = 0; i < resultword.Count(); i++)
        {
            if (resultword[i] == ' ')
            {
                Console.Write(word[i]);
            }
            else
            {
                Console.Write("_");
            }
        }
    }

    Console.WriteLine();
}
while (tries-- != 0 && resultword.Trim() != string.Empty);

怎么样：

static void Main(string[] args)
{

    string[] words = new string[] { "Apple", "Banana", "Pear", "Pineapple", "Melon"};
    Random random = new Random();

    string wordToGuess = words[random.Next(5)].ToLower();
    char[] currentLetters = new char[wordToGuess.Length];
    for (int i = 0; i < currentLetters.Length; i++) currentLetters[i] = '_';
    int numTries = currentLetters.Length + 1;
    bool hasWon = false;
    do
    {
        string input = Console.ReadLine().ToLower();
        if (input.Length == 1) //guess a letter
        {
            char inputChar = input[0];
            for (int i = 0; i < currentLetters.Length; i++)
            {
                if (wordToGuess[i] == inputChar)
                {
                    currentLetters[i] = inputChar;
                }
            }
            if (!currentLetters.Contains('_'))
            {
                hasWon = true;
            }
            else
            {
                Console.WriteLine(new string(currentLetters));
            }
        }
        else
        {
            if (input == wordToGuess)
            {
                hasWon = true;
            }
            else
            {
                Console.WriteLine("Incorrect!");
                Console.WriteLine(new string(currentLetters));
            }
        }

        numTries--;

    } while (new string(currentLetters) != wordToGuess && numTries > 0 && !hasWon);

    if (hasWon)
    {
        Console.WriteLine("Congratulations, you guessed correctly.");
    }
    else
    {
        Console.WriteLine("Too bad! Out of tries");
    }
}

您的主要问题是您只跟踪当前的猜测，而不是所有以前的猜测。您可以使用 aHashSet来跟踪您之前的猜测。HashSet<char> guessedLetters所以在你的do循环之前定义一个变量，然后在你解析 "guess" do 之后作为循环中的第二行guessedLetters.Add(guess)。然后用if(item==guess)替换if(guessedLetters.Contains(item))。中提琴，只需三行代码更改！

最后你的退出条件可以是while (word.Any(c=>!guessedChars.Contains(c)) && --tries != 0);.

怎么样，使用你现有的代码；

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

您提到了尝试次数，但您在使用后从未在代码中使用它。大概，您想要执行以下操作：

  • 选择一个随机单词（在您的情况下，您选择用户提供的五个单词之一）
  • 设置猜测（尝试？）的次数等于单词的长度加 2。如果他们猜出一个存在的字母，那么它是免费的。如果这封信不存在，那么他们就会失去其中一个猜测。
  • 在每次猜测之前，将所有未猜到的字母都替换为“_”来显示单词。
  • 当用户猜测存在的字母时，将显示的单词中的“_”替换为该字母。

这是一些应该可以工作的示例代码（未经测试）：

    string displayword = String.Copy(word);
    for (int j = 0; j < displayword.length; j++) displayword[j]='_';
    do {
        // Display the word so far.
        Console.WriteLine("Word is {0}", displayword);

        // Get a guess from the user
        char guess = char.Parse(Console.ReadLine());
        if (word.Contains(guess)) {
            for (j=0; j<word.length; j++) {
              if (word[j] == guess) displayword[j]=guess;
            }
        } else {
          // Decrease the tries.
          tries--;
        }
    } while (displayword.Contains("_") && (tries > 0));

到目前为止，您需要将输入词与结果区分开来。用下划线初始化结果，然后在人们猜测时将字母添加到结果中。如果你制作result一个 char 数组而不是字符串，它会更容易一些。

        var result = new string('_', word.Length).ToCharArray();
        do
        {
            char guess = char.Parse(Console.ReadLine());
            for (var i = 0; i < word.Length; ++i)
            {
                if(word[i] == guess)
                {
                    result[i] = guess;
                }
            }
            Console.WriteLine(new string(result));
        }
        //If my word contains A "_" i will keep looping
        while (result.Contains('_') && --tries != 0);
