如何使用许多子节点反序列化XML [英] How to de-serialize XML with many child nodes

问题描述

如果我的XML是这样的：

If my XML is like this:

<Item>
    <Name>Jerry</Name>
    <Array>
        <Item>
            <Name>Joe</Name>
        </Item>
        <Item>
            <Name>Sam</Name>
        </Item>
    </Array>
</Item>

我可以将其序列化为此类：

I can serialize it into this class:

[DataContract(Namespace = "", Name = "dict")]
public class Item
{
    [DataMember(Name = "Name")]
    public string Name { get; set; }
    [DataMember(Name = "Array")]
    public IEnumerable<Item> Children { get; set; }
}

但是如果我的XML是这样的呢？

But what if my XML is like this?

<Item>
    <Name>Jerry</Name>
    <Item>
        <Name>Joe</Name>
    </Item>
    <Item>
        <Name>Sam</Name>
    </Item>
</Item>

这不起作用：

[DataContract(Namespace = "", Name = "Item")]
public class Item
{
    [DataMember(Name = "Name")]
    public string Name { get; set; }
    [DataMember(Name = "Item")]
    public IEnumerable<Item> Children { get; set; }
}

什么是装饰教室的正确方法？

推荐答案

如果要控制xml，则 XmlSerializer 是的方式，而不是 DataContractSerializer 。后者只是缺少 XmlSerializer 提供的细粒度控制；在这种情况下，对于列表/数组布局之类的东西-但是即使 xml属性也是 DataContractSerializer 的问题。就是这样：

If you want control over xml, then XmlSerializer is the way to go, not DataContractSerializer. The latter simply lacks the fine-grained control that XmlSerializer offers; in this case for things like list/array layout - but even just xml attributes are a problem for DataContractSerializer. Then it is just:

public class Item {
    public string Name { get; set; }
    [XmlElement("Item")]
    public List<Item> Children { get; set; }
}
public class Item {
    public string Name { get; set; }
}

和：

var serializer = new XmlSerializer(typeof(Item));
var item = (Item) serializer.Deserialize(source);
