反序列化要列出的数组元素

本文关键字:数组元素 反序列化 | 更新日期: 2023-09-27 18:24:54

我有以下XML。。。

<configuration>
    <img name="name1" />
    <img name="name2" />
    <warn>
        <img name="warn1" />
    </warn>
</configuration>

我试图将其反序列化为。。。

[XmlType("img")]
public class ImageNameExceptionItemXml
{
    [XmlAttribute("name")]
    public string Filename;
}
[XmlRoot("configuration")]
public class ImageNameExceptionListXml: List<ImageNameExceptionItemXml>
{
    [XmlArray("warn")]
    [XmlArrayItem("img")]
    public ImageNameExceptionListXml WarnList { get; set; }
}

但我的WarnList属性为null。

我已经试过了。。。

[XmlElement("warn"}]
public ImageNameExceptionListXml WarnList { get; set; }

[XmlElement("warn"}]
public List<ImageNameExceptionItemXml> WarnList { get; set; }

但我最终仍然使用WarnList属性null。为什么?

反序列化要列出的数组元素

让我们来解决这个问题。警告是一个"根"元素,因此,您也必须在类中转换它:

xml:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <img name="name1" />
  <img name="name2" />
  <warn>
      <img name="warn1" />
      <img name="warn2" />
  </warn>
</configuration>

类别:

[XmlType("img")]
public class ImageNameExceptionItemXml 
{ 
    [XmlAttribute("name")]     
    public string Filename; 
}
[XmlType("warn")]
public class WarnExceptionItemXml
{
    [XmlElement("img")]
    public List<ImageNameExceptionItemXml> ImgList { get; set; }
}
[XmlRoot("configuration")]
public class ImageNameExceptionListXml
{
    [XmlElement("img")]
    public List<ImageNameExceptionItemXml> ImgList { get; set; }
    [XmlElement("warn")]
    public WarnExceptionItemXml WarnList { get; set; } 
}

以及反序列化测试:

XmlSerializer xml = new XmlSerializer(typeof(ImageNameExceptionListXml));
ImageNameExceptionListXml teste = (ImageNameExceptionListXml)xml.Deserialize(new FileStream("XMLFile1.xml", FileMode.Open));
XmlSerializer只允许数组/列表中有一个类型。很好。张贴我的测试代码:
[XmlType("img")]
[Serializable]
public class ImageNameExceptionItemXml
{
    [XmlAttribute("name")]
    public string Filename;
}
[XmlType("warn")]
[Serializable]
public class Warnning
{
    [XmlArrayItem(typeof(ImageNameExceptionItemXml))]
    public List<ImageNameExceptionItemXml> imgs { get; set; }
}
[XmlRoot("configuration")]
[Serializable]
public class ImageNameExceptionListXml
{
    [XmlArrayItem(typeof(Warnning))]
    public List<Warnning> warns{ get; set; }
    [XmlArrayItem(typeof(ImageNameExceptionItemXml))]
    public List<ImageNameExceptionItemXml> imgs { get; set; }
}

xml:

<configuration>
<imgs>
    <img name="name1" />
    <img name="name2" />
</imgs>
<warns>
    <warn>
      <imgs>
        <img name="warn2" />
        <img name="warn1" />
      </imgs>
    </warn>
    <warn>
      <imgs>
        <img name="warn3" />
        <img name="warn4" />
      </imgs>
    </warn>
 </warns>
</configuration>
