XMLReader 错误表示 xml 文件中的元素

Question

如何使用 XmlReader 读取以下格式的 XML 文件？我已经做了好几天了，但无济于事。当它到达<text> 元素时，读者将其读取为结束元素并忽略该值...不知道为什么...

<?xml version="1.0" encoding="UTF-8"?>
<questions>
   <question>
      <question_number>1</question_number>
      <text>DDDDDFFFFJJJJ</text>
      <option>
         <id>1</id>
         <response>DDDF</response>
      </option>
      <option>
         <id>2</id>
         <response>FF</response>
      </option>
      <option>
         <id>3</id>
         <response />
      </option>
      <option>
         <id>4</id>
         <response />
      </option>
   </question>
</questions>

我尝试了以下方法，但无济于事：

public bool ImportQuestions(string FileName)
    {
        try
        {
            XmlTextReader reader = new XmlTextReader(FileName);
            while (reader.Read())
            {
                if (reader.Name == "question")
                {
                    Question question = new Question();
                    var subReader = reader.ReadSubtree();
                    while (subReader.Read())
                    {
                        if (subReader.Name == "question_number")
                        {
                            question.Id = subReader.ReadElementContentAsInt();
                        }else if (subReader.Name == "text")
                        {
                            question.QuestionText = subReader.ReadElementContentAsString();
                        } else if (subReader.Name == "option")
                        {
                            Option option = new Option();
                            var ansReader = subReader.ReadSubtree();
                            while (ansReader.Read())
                            {
                                if (ansReader.Name == "id")
                                {
                                    option.ID = ansReader.ReadElementContentAsString();
                                }else if (ansReader.Name == "response")
                                {
                                    option.Response = ansReader.ReadElementContentAsString();
                                }
                            }
                            question.AddToAnswers(option);
                        }

                    }
                    Questions.Add(question);
                }

            }
            reader.Close();

        }
        catch (Exception ex)
        {
            return false;
        }
        return true;
    }

Answer 1

我已经做了好几天了，但无济于事。

让我用LINQ to XML 让它变得更简单，只需像这样添加两个类Question 和Option：

public class Question
{
    public int Number { get; set; }
    public string Text { get; set; }
    public List<Option> Options { get; set; }
}

public class Option
{
    public int Id { get; set; }
    public string Response { get; set; }
}

然后使用LINQ to XML:

XDocument xDoc = XDocument.Load("filepath");
var questions = xDoc.Descendants("question").Select(q => new Question
        {
            Number = (int) q.Element("question_number"),
            Text = (string) q.Element("text"),
            Options = (from op in q.Elements("option")
                select new Option
                {
                    Id = (int) op.Element("id"),
                    Response = (string) op.Element("response")
                }).ToList()
        }).ToList();
