无法将 XML 字符串反序列化为包含列表的对象

Question

这是我的序列化方法：

public static T DeserializeFromXml<T>(string xml)
{
    try
    {
         var root = new XmlRootAttribute()
         {
             ElementName = "PatientDS",
             Namespace = ""
         };

         T result;
         var serializer = new XmlSerializer(typeof(T), root);
         using (TextReader reader = new StringReader(xml))
         {
            result = (T)serializer.Deserialize(reader);
         }
         return result;
    }
    catch (Exception ex)
    {
        return default(T);
    }
}

public static string Serialize<T>(T obj)
{
    try
    {
       var serializer = new XmlSerializer(typeof(T));
       using (var writer = new StringWriter())
       {
           serializer.Serialize(writer, obj);
           return writer.ToString();
       }
    }
    catch (Exception ex)
    {
        return String.Empty;
    }
}

这是我要反序列化的对象：

public class PatientDS
{
    [XmlElement("Patient")]
    public Patient Patient { get; set; }
}

    [Serializable]
    public class Patient
    {
        [XmlElement("PatientID")]

        [XmlElement("Gender")]
        public string Gender { get; set; }

        public string PatientCategory { get; set; }

        [XmlElement("SiteOfDisease")]
        public string SiteOfDisease { get; set; }

        [XmlElement("Outcome")]
        public string Outcome { get; set; }

        [XmlElement("RegistrationYear")]
        public int RegistrationYear { get; set; }

        [XmlElement("RegistrationNo")]
        public int RegistrationNo { get; set; }

        [XmlElement("RegistrationDate")]
        public DateTime RegistrationDate { get; set; }

        [XmlElement("Name")]
        public string Name { get; set; }

        [XmlElement("Surname")]
        public string Surname { get; set; }

        [XmlElement("IDNumber")]
        public string IDNumber { get; set; }

        [XmlElement("BirthDate")]
        public DateTime BirthDate { get; set; }

        [XmlElement("TypeOfResistantTB")]
        public string TypeOfResistantTB { get; set; }

        [XmlElement("TreatmentStartDate")]
        public DateTime TreatmentStartDate { get; set; }

        [XmlElement("OutcomeDate")]
        public DateTime OutcomeDate { get; set; }

        [XmlElement("IsActive")]
        public bool IsActive { get; set; }

        [XmlElement("IsTreatmentStarted")]
        public bool IsTreatmentStarted { get; set; }

        [XmlElement("TypeOfResistantTBConfirmation")]
        public string TypeOfResistantTBConfirmation { get; set; }

        [XmlElement("HIVStatus")]
        public string HIVStatus { get; set; }

        [XmlArray("PatientDSTDS")]
        [XmlArrayItem("PatientDST")]
        public List<PatientDST> PatientDSTDS { get; set; }

        [XmlElement("PatientHIVTestDS")]
        public List<PatientHIVTest> PatientHIVTestDS { get; set; }

        [XmlElement("PatientDSTAdvancedDS")]
        public List<PatientDSTAdvanced> PatientDSTAdvancedDS { get; set; }

        [XmlElement("PatientSecondLineDrugDS")]
        public List<PatientSecondLineDrug> PatientSecondLineDrugDS { get; set; }

        [XmlElement("PatientSputumDS")]
        public List<PatientSputum> PatientSputumDS { get; set; }
    }

这里是 XML:

问题是我能够反序列化这个对象，并且所有普通元素都填充了正确的值，但是我无法获取要填充的 List<> 属性。

我在这里做错了什么或遗漏了什么？

Answer 1

实际上，当我使用 XML 和上面的示例代码时，它并没有为我填充任何字段。我不完全清楚你是直接将海水淡化到 Patient 中，但是当我添加一个 PatientDS class 时，它是 XML 中的根，它填充了所有字段，包括所有列表。我刚刚添加了这一点：

public class PatientDS
{
    [XmlElement("Patient")]
    public Patient Patient { get; set; }
}

我这样反序列化：

string xml = File.ReadAllText("XMLFile1.xml");
var patient = DeserializeFromXml<PatientDS>(xml);

并且输出看起来不错：

希望这就是您要找的。

Answer 2

试试这个：

[XmlRoot(ElementName = "PatientDS")]
public class PatientDS
{
   public Patient Patient { get; set; }
}

[XmlRoot(ElementName = "Patient")]
public class Patient
{
   //stuff
}

并反序列化它。

Answer 3

我发现了问题。

在阅读了有关 XML 中读取日期的更多信息后，我认为此 XML 的子项中提供的日期无效（ISO 8601）标准，因此我的应用程序遇到了困难阅读它，但失败了。

因为这是一个虚拟对象 XML，我实例化了一个新的 PersonDS 对象，将其反序列化为 XML，然后反序列化以检查应用程序是否正常工作，并且它没有序列化问题。

感谢大家的帮助。
