C# 循环浏览随机字母，直到拼写单词

好的，所以我想知道如何在 C# 控制台应用程序中执行此操作。

基本上，我希望能够生成一个带有随机字母的字符串，在一个循环中，我希望字符串的每个字符都替换为另一个随机字符，直到拼写一个单词。例如：

asdfjnb (初始字符串(索夫内克茨德克吉克teiuhft(随机生成字符串，生成后保留正确的字母(特斯涅格泰斯特达见证测试(最终字符串(

C# 循环浏览随机字母，直到拼写单词

另一个例子...

    static void Main(string[] args)
    {
        Random r = new Random();
        string letters = "abcdefghijklmnopqrstuvwxyz";
        List<string> dictionary = new List<string>(new string[] { 
            "compartmentalization", "inheritance", "polymorphism", 
            "paradigm", "abstraction", "aggregration", "cryptography",
            "pseudocode", "recursion", "backtracking", "alogrithm"
        });
        string word = dictionary[r.Next(dictionary.Count)];
        List<int> indexes = new List<int>();
        StringBuilder sb = new StringBuilder();
        for(int i = 0; i < word.Length; i++)
        {
            sb.Append(letters[r.Next(letters.Length)]);
            if (sb[i] != word[i])
            {
                indexes.Add(i);
            }
        }
        Console.WriteLine(sb.ToString());
        while(indexes.Count > 0)
        {
            int index;
            for(int i = indexes.Count - 1; i >= 0; i--)
            {
                index = indexes[i];
                sb[index] = letters[r.Next(letters.Length)];
                if (sb[index] == word[index])
                {
                    indexes.RemoveAt(i);
                }
            }
            Console.WriteLine(sb.ToString());
        }
        Console.ReadLine();
    }

我假设在开始此过程之前，该问题有一个特定的目标字符串。

将字符串视为一个char数组，或显式将其转换为该数组。每次迭代都应根据其"目标"字符检查字符串中的每个字符。如果当前字符 == 目标字符，则不要为其选择新值。

// These specified somewhere
char[] goalstring;
char[] currentstring;
// Randomized correct logic
bool finished = false;
while (!finished)
{
    finished = true;
    for (int i = 0; i < goalstring.length; ++i)
    {
         if (currentstring[i] != goalstring[i])
         {
              finished = false;
              // this function returns a random char according to your design
              currentstring[i] = GetRandomLetter(); 
         }
    }
    // render text to screen
    PrintCurrentString(currentstring);
}

获取随机字符相当容易，您可以使用 Random 类获取指定范围的int，并将其转换为 char 。您选择的边界将确定达到目标所需的平均时间，以及要从中选择的字符集。
