从自定义文件中读取值-仅读取第一个值

Question

我试图从保存的自定义文件中读取值，但它始终只读取列表中的第一个字符串。

例如，我在列表中保存了两个单词（“ FIRST”，“ SECOND”），使用下面的代码将成功保存两个单词，但是当反序列化文件以读取文件时，它仅使用第一个单词“ FIRST”覆盖它”。

读取方法：

 public static List<string> GetBonusList()
        {             
            if (File.Exists(GetCurrentGamePath()))
            {
                BinaryFormatter formatter = new BinaryFormatter();
                FileStream existingFile = File.Open(GetCurrentGamePath(), FileMode.Open);

                gameList = (List<Game>)formatter.Deserialize(existingFile);

                existingFile.Close();

                foreach (Game game in gameList.Where(x => x.GameName == gameName))
                {
                    if (game.FoundBonusWordsList != null)
                        return game.FoundBonusWordsList;
                    else
                        return null;
                }

                Debug.Log("No bonus words found yet!");
                return null;
            }
            else
            {
                Debug.Log("File doesn't exists yet.");
                return null;
            }
        }

保存方法：

public static void SaveBonusWord(string bonusWord)
    {
        BinaryFormatter formatter = new BinaryFormatter();

        /// Check if there is a file 
        /// containing revealed word OR bonus words OR both.
        if (File.Exists(GetCurrentGamePath()))
        {
            FileStream existingFile = File.Open(GetCurrentGamePath(), FileMode.Open);
            gameList = (List<Game>)formatter.Deserialize(existingFile);

            foreach (var existingGame in gameList.Where(x => x.GameName == gameName))
                if (existingGame.FoundBonusWordsList.Contains(bonusWord) == false)               
                    existingGame.FoundBonusWordsList.Add(bonusWord);

            formatter.Serialize(existingFile, gameList);
            existingFile.Close();
        }
        else
        {
            Debug.Log("No boardWord or bonusWord found yet. Creating new game..");

            FileStream file = File.Create(GetCurrentGamePath());
            Game game = new Game
            {
                GameName = gameName
            };
            game.FoundBonusWordsList.Add(bonusWord);
            gameList.Add(game);

            formatter.Serialize(file, gameList);
            file.Close();
        }
    }
