我无法从另一个文件的列表中随机选择单词。
事实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一下:)
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，但首先粘贴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
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
class Hangman
{
static void Main(string[] args)
{
Console.ForegroundColor = ConsoleColor.Red;
Console.Title = "C# Hangman";
Console.WriteLine("Welcome To C# Hangman!");
//MENU
int MenuChoice = 0;
while (MenuChoice != 4)
{
Console.Write("\n\t1) Add words");
Console.Write("\n\t2) Show list of words");
Console.Write("\n\t3) Play");
Console.Write("\n\t4) Quit\n\n");
Console.Write("\n\tChoose 1-4: "); //Choose meny item
MenuChoice = Convert.ToInt32(Console.ReadLine());
WordList showing = new WordList();
switch (MenuChoice)
{
case 1:
Console.Write("\n\tAdd a word\n\n");
var insert = Console.ReadLine();
showing.AddWord(insert);
Console.Write("\n\tList of words\n\n");
showing.ListOfWords();
break;
case 2:
Console.Write("\n\tList of words\n\n");
showing.ListOfWords();
break;
case 3: //Running game
int numGuessesInt = -1;
while (numGuessesInt == -1)
{
/* Sets the number of guesses the user has to guess the word*/
pickNumGuesses(ref numGuessesInt);

/* Creates a list of characters that will show */

* If nothing is correct string will return "_ _ _ " */
string wordToDisplay = displayWord(guessedLetters, word);
/* If the string returned contains the "_" character, all the
* correct letters have not been guessed, so checking if user
* has lost, by checking if numGuessesLeft is less than 1.*/
if (!wordToDisplay.Contains("_"))
{
solved = true;
Console.WriteLine("You Win! The word was " + word);
/* Check if the user wants to play again. If they do,
* then solved is set to true, will end the loop,
* otherwise, checkIfPlayAgain will close the program.*/
checkIfPlayAgain();

checkIfPlayAgain();
}
else
{
/* If the user has not won or lost, call guessLetter,
* display the word, minus guesses by 1*/
guessLetter(guessedLetters, word, wordToDisplay, ref numGuessesInt);
}
}
break;
case 4:
Console.WriteLine("\n\tEnd game?\n\n");
break;
default:

}
这是 WordList.cs 的代码
using System;
using System.Collections.Generic;
class WordList
{
List <string> words = new List<string>();
public 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 void AddWord(string value){
words.Add(value);
}
}
