使用多个元素属性反序列化XML文件 - 属性不反序列化

Question

使用C#.Net 4 - XML示例(真实示例有6个属性)

<TestXML>
  <TestElement attr1="MyAttr" attr2="1" DateAdded="">25</TestElement>
</TestXML>

对于我的班级定义,我有以下内容:

public class TestXML() {
   public TestXML() {}

   public int TestElement {get; set;}
   [XmlAttribute]
   public string attr1 {get; set;}
   [XmlAttribute]
   public string attr2 {get; set;}
   [XmlIgnore]
   public DateTime DateAdded {get; set;}
   [XmlAttribute("DateAdded")]
   public string dateadded {
      get{ return (DateAdded == null ? "" : DateAdded.ToString();}
      set{ if(!value.Equals("")) DateAdded = DateTime.Parse(value);}
   }
}

现在反序列化的代码:

string xml = "<TestXML><TestElement attr1=\"MyAttr\" attr2=\"1\" DateAdded=\"\">26</TestElement></TestXML>"
using (StringReader sr = new StringReader(xml)) {
   XmlSerializer serializer = new XmlSerializer(typeof(TestXML));
   TestXML myxml = (TestXML)serializer.Deserialize(sr);
}

现在我们得到的结果是(在VS中查看对象):

myxml
  attr1         |  null
  attr2         |  null
  TestElement   |  25

完全丧失了为什么属性不会反序列化.

Answer 1

要做到这一点,你需要两个级别:

[XmlRoot("TestXML")]
public class TestXml {
    [XmlElement("TestElement")]
    public TestElement TestElement { get; set; }
}

public class TestElement {
    [XmlText]
    public int Value {get;set;}

    [XmlAttribute]
    public string attr1 {get;set;}

    [XmlAttribute]
    public string attr2 {get;set;}
}

请注意,> 26 <也可能导致问题(空白); 您可能需要将其作为字符串而不是int.
