如何反序列化文档XML：

---------------------------------- -----------

How deserialize document XML:

</something>

我无法获得物品价值元素

---------------------------------------------

I can't get value elemnts in item
---------------------------------------------

[XmlRoot("something")]
    public class Something: ClassBase
    {
       [XmlAttribute("id")]
        public string id;

       [XmlArray("items")]
       public ItemsCollection forms { set; get; } 

       public Something(): base() { }
    }


    [XmlType("item")]
    public class ItemsCollection: CollectionClassBase<Item>
    {
        public ItemsCollection() : base() { }
    }


    [XmlType("item")]
    public class Item: ClassBase
    {
        [XmlAttribute("name"), DefaultValue("")]
        public string name { set; get; }
    }

    [XmlType("item")]
    public class ItemObj1 : Item
    {
        [XmlElement("a"), DefaultValue("")]
        public string a  { set; get; }
        [XmlElement("b"), DefaultValue("")]
        public string b { set; get; }
    }

推荐答案

我建​​议使用xsd.exe工具 [ ^ ]可以从xml生成正确的类定义。



请按照以下步骤操作：使用xsd.exe自动生成实体类，用于XML序列化和反序列化 [ ^ ]





我建议改变你的XML结构：

I'd suggest to use xsd.exe tool[^] which can generate proper class(es) definition from xml.

Follow these steps: Auto generating Entity classes with xsd.exe for XML Serialization and De-Serialization[^]


I'd suggest to change your XML structure:

<something id="234">
     <items>
          <item name="Obj1">
               <a>1</a>
               <k>1</k>

to：

to:

<something id="234">
     <items>
          <item name="Obj1">
               <property name="a">1</a>
               <property name="k">1</k>

它应该在XML规范化时帮助你。

It should help you while XML normalization.
