c# - 从类(class)获取列表时出错

Question

我创建了这个类:

class Riconoscimento
{
    private List<Word> words = new List<Word>();


    public List<Word> GetList()
    {
        return words;
    }

    public void loadWords()
    {
        string[] lines = File.ReadAllLines(Environment.CurrentDirectory + "/../../words.txt");
            foreach (string line in lines)
            {
                // skip commentblocks and empty lines..
                if (line.StartsWith("--") || line == String.Empty) continue;

                // split the line
                var parts = line.Split(new char[] { '|' });

                // add commandItem to the list for later lookup or execution
                words.Add(new Word() { Text = parts[0], AttachedText = parts[1], IsShellCommand = (parts[2]) });


            }
      }
}

但是在加载 loadWords() 之后，当我尝试使用 MainForm 中的类获取单词时

 public void engine_WordsRecognized(object sender, SpeechRecognizedEventArgs e)
    {
        Riconoscimento _riconoscimento = new Riconoscimento();
        List<Word> words = _riconoscimento.GetList();
        var cmd = words.Where(c => c.Text == e.Result.Text).First();
}

此错误发生: System.InvalidOperationException - 序列不包含元素。

好像无法从类中检索单词，我不明白为什么。如果我不使用该类，而是将所有内容都放在我的主代码中，它就可以工作。我该怎么办？

问题已解决:我在我的另一个空隙中加载了 loadWords()，我不得不将它加载到我的另一个空隙中。

Answer 1

您没有调用 loadWords()。这就是没有加载任何内容的原因。

public void engine_WordsRecognized(object sender, SpeechRecognizedEventArgs e)
{
    Riconoscimento _riconoscimento = new Riconoscimento();
    _riconoscimento.loadWords();
    List<Word> words = _riconoscimento.GetList();
    var cmd = words.Where(c => c.Text == e.Result.Text).First();
}
