XMLReader在xml文件中歪曲元素

Question

如何使用XmlReader讀取具有以下格式的XML文件？ 我已經好幾天了，但無濟於事。 當它到達<text>元素時，讀者將其作為結束元素讀取並忽略該值...不知道為什么......

<?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>

我嘗試了以下但無濟於事：

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

我已經好幾天了，但無濟於事。

讓我使用LINQ to XML更容易，只需添加兩個類Question和Option如下所示：

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();
