Question

我试图制作一个game子手游戏，它从单词的文本文件中选择一个随机单词。然后以星号显示该单词，并要求用户猜出单词的每个字母（如果猜对了），并发现该字母，然后继续播放直到猜到单词中的所有字母。猜出单词后将显示数字错过，问他们是否想再次比赛。

我遇到的问题是，正确猜出该单词时，即使发现该单词，它也会不断要求输入字母。我不确定如何解决此问题。我想尽可能不使用linq来执行此操作。任何帮助都会被

        char[] guessed = new char[26];
        char guess = ' ';

        bool validAnswer = false;


        int amountMissed = 0, index = 0;

        do
        {
            // initilization of word and testword so that we could generate a testword with the same length as original
            char[] word = RandomLine().Trim().ToCharArray();

            char[] testword = new string('*', word.Length).ToCharArray(); 
            char[] copy = word;

            Console.WriteLine(testword);

有多种比较两个数组/列表的方法。我看到的用于字符数组/列表的简单方法是将它们转换为字符串，然后进行比较。

Array Comparison thread on stackoverflow

testword.ToString() != word.ToString()

关于Flydog57，使用this link学习如何调试代码：

Answer 2

使用“ SequenceEqual”而不是！=比较数组。这样，您将需要将while语句更改为：

while (!testword.SequenceEqual(word))

Quartermeister对此进行了说明，ohn Buchanan在问题“在C＃中比较数组的最简单方法”中作了进一步解释。链接在这里：

Easiest way to compare arrays in C#

否则很棒的程序！

请注意，当您尝试调试时，我想输入的一个简单内容是，如果我无法通过调试弄清楚，我最初希望看到什么响应。您以后可以随时删除该行。我将此放在while语句的末尾。

Console.WriteLine(testword.SequenceEqual(word));
