使用XmlSerializer忽略外部元素 [英] Ignore outer elements using XmlSerializer
问题描述
我正在尝试反序列化XML文档:
I am trying to deserialize the XML document:
<?xml version='1.0' encoding='UTF-8'?>
<eveapi version="2">
<currentTime>2013-07-07 07:24:20</currentTime>
<result>
<rowset name="characters" key="characterID" columns="name,characterID,corporationName,corporationID">
<row name="xxxxx" characterID="1234" corporationName="xxxx" corporationID="1234" />
</rowset>
</result>
<cachedUntil>2013-07-07 07:40:39</cachedUntil>
</eveapi>
我的模特是:
[XmlRoot("rowset")]
public class CharacterList
{
public CharacterList() { Characters = new List<Character>(); }
[XmlElement("row")]
public List<Character> Characters { get; set; }
}
public class Character
{
[XmlElement("name")]
private string name { get; set; }
[XmlElement("characterID")]
private int Id { get; set; }
[XmlElement("corporationName")]
private string corporationName { get; set; }
[XmlElement("corporationID")]
private int corporationId { get; set; }
}
我的反序列化代码是:
XmlRootAttribute xRoot = new XmlRootAttribute();
xRoot.ElementName = "result";
xRoot.IsNullable = true;
var serializer = new XmlSerializer(typeof(Character), xRoot);
var list = (CharacterList) serializer.Deserialize(output);
但是,我遇到一个例外:
However, I am getting an exception:
System.InvalidOperationException: There is an error in XML document (2,2).
具有内部类型:
System.InvalidOperationException: <eveapi xmlns=''> was not expected.
我很确定这是因为不需要我的外部信息.有没有办法我可以忽略它?我的另一个想法是,我可以为模式的其余部分编写包装器类,然后忽略我不关心的内容.但是,我希望有一种更简单的方法.我已经坚持了一段时间,将不胜感激.
I'm pretty sure this is because of the outer information I do not need. Is there a way I can ignore it? my other thought was I could write wrapper classes for the rest of the schema, then just ignore what I don't care about. However, I was hoping there is an easier way. I've been stuck on this for a while, any help would be appreciated.
推荐答案
您可以使用XmlReader导航到内部元素,然后从此处使用XmlSerializer:
You can use an XmlReader to navigate to the inner element and use the XmlSerializer from there:
using (XmlReader reader = XmlReader.Create("c:\\your.xml"))
{
reader.MoveToContent();
reader.ReadToDescendant("rowset");
var serializer = new XmlSerializer(typeof(CharacterList));
var list = (CharacterList)serializer.Deserialize(reader);
}
请注意,您的模型中还存在一些问题:
Please also note that there are also some issues in your model:
- 财产应该是公开的.
- 使用XmlAttribute代替XmlElement作为属性
-
使用typeof(CharacterList)代替typeof(Character)
- Properties should be public.
- Use XmlAttribute for attributes instead of XmlElement
Use typeof(CharacterList) instead of typeof(Character)
[XmlRoot("rowset")]
public class CharacterList
{
public CharacterList() { Characters = new List<Character>(); }
[XmlElement("row")]
public List<Character> Characters { get; set; }
}
public class Character
{
[XmlAttribute("name")]
public string name { get; set; }
[XmlAttribute("characterID")]
public int Id { get; set; }
[XmlAttribute("corporationName")]
public string corporationName { get; set; }
[XmlAttribute("corporationID")]
public int corporationId { get; set; }
}
