我无法从另一个文件的列表中选择一个随机单词。实际上，我什至无法让它选择任何单词。我不确定如何连接这两个文件。希望有人能帮忙，我是初学者，所以请尽可能简单地解释:)

我有 2 个文件，一个名为 program.cs，另一个名为 WordList.cs。我将粘贴所有代码，但首先是我遇到问题的小片段。我只是不知道如何正确编写代码。

这是称为 Pick word 的小部分：

 //PICK WORD

    static string pickWord()
    {
        string returnword = "";

        TextReader file = new StreamReader(words);
        string fileLine = file.ReadLine();


        Random randomGen = new Random();
        returnword = words[randomGen.Next(0, words.Count - 1)];
        return returnword;
    }

这是 Program.cs 中的所有代码

我对您的代码进行了一些更改。该代码现在可以工作，但远非完美。您的解决方案有两个文件Program.cs和Wordlist.cs，看起来像这样

     *   make variables private if you use them on several methods

尝试创建一个静态类并添加一个返回列表的方法，然后您将能够访问您的单词表。

例子：

static class WordList
{
   static List<string> words = new List<string>();

   public static  void ListOfWords()
   {
       words.Add("test");         // Contains: test
       words.Add("dog");          // Contains: test, dog
       words.Insert(1, "shit"); // Contains: test, shit, dog

       words.Sort();
       foreach (string word in words) // Display for verification
       {
           Console.WriteLine(word);
       }

   }

   public static List<string> GetWords()
   {
      return words;
   }

   public static void AddWord(string value)
   {
       words.Add(value);
   }
}

然后，您将更改您的 switch 语句，使其看起来像这样。

switch (MenuChoice)
{
    case 1:               
        Console.Write("\n\tAdd a word\n\n");
        var insert = Console.ReadLine();
        WordList.AddWord(insert);
        Console.Write("\n\tList of words\n\n");
        WordList.ListOfWords();                
        break;
    case 2:
        Console.Write("\n\tList of words\n\n");
        WordList.ListOfWords();
        break;

    ....

你的pickWord方法看起来像这样：

static string pickWord()
{
    string returnword = "";

    Random randomGen = new Random();
    returnword = WordList.GetWords()[randomGen.Next(0, WordList.GetWords().Count() - 1)];
    return returnword;
}

我修改了您的 Wordlist 类，以便它可以使用一个文件在您的程序使用之间维护您的单词，以防万一这就是您所要求的。

static class WordList
{
    static string filePath = @"C:\temp\Word.txt";
    static List<string> words = new List<string>();
    private static void CheckFile()
    {
       //Makes sure our base words are saved to the file
       if (!File.Exists(@"C:\temp\Word.txt"))
       {
           using (TextWriter writer = new StreamWriter(filePath))
           {
               writer.WriteLine("test");
               writer.WriteLine("dog");
               writer.WriteLine("shit");
           }
       }
   }

   public static  void ListOfWords()
   {
       CheckFile();
       words.Clear();
       using (TextReader file = new StreamReader(filePath))
       {
           char[] delineators = new char[] { '\r', '\n' };
           string[] tempWords = file.ReadToEnd().Split(delineators, StringSplitOptions.RemoveEmptyEntries);

           foreach (string line in tempWords)
           {
               words.Add(line);
           }

       }


       foreach (string word in words) // Display for verification
       {
           Console.WriteLine(word);

       }

   }

   public static List<string> GetWords()
   {
      return words;
   }

   public static void AddWord(string value)
   {
       CheckFile();
       using (TextWriter writer = new StreamWriter(filePath,true ))
       {
           writer.WriteLine(value);
       }
   }
}

这是一个非常简单的解决方案：

只需一次填充您的列表，或者当您添加任何单词时，调用此方法。代码：

private void PopulateTheWordList()
        {
            Console.Write("\n\tAdd a word\n\n");
            WordList.Add(Console.ReadLine());
        }

现在只需调用此方法即可获取随机单词：

private string PickWord()
        {
            Random ran = new Random();
            return WordList[ran.Next(0, WordList.Count)];
        }

如果您需要在另一个类中创建Listof words，则使用关键字static：

static List<string> WordList = new List<string>();

现在你可以通过写类名来调用它，比如YourClassName.WordList
