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;
    }
}

这是我试图反序列化的对象：

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

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

        public DateTime RegistrationDate { get; set; }

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

        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，但我无法得到List＆lt;＆gt;要填充的属性。

我在这里做错了什么或错过了什么？

Answer 1

实际上，当我使用上面的XML和示例代码时，它并没有为我填充任何字段。我并不完全清楚您是否已直接对患者进行脱盐，但当我添加一个PatientDS类时，它是XML的根，它填充了所有字段，包括所有列表。我刚刚补充了这一点：

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);

并且输出似乎很好：

希望这就是你要找的东西。

Answer 2

试试这个：

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

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

将其反序列化。

Answer 3

我发现了问题。

在阅读了有关从XML读取日期的更多信息之后，我认为此XML子项中提供的日期无效（ISO 8601）标准，因此我的应用程序正在努力阅读它并失败。

由于这是一个虚拟XML，我实例化了一个新的PersonDS对象，将其反序列化为XML，然后序列化以检查应用程序是否正常工作，并且序列化没有问题。

感谢所有人的帮助。
