我正在寻找有关如何实现和/或更改以下类的类序列化行为的提示,想法.

简化(不完整)样本类：

[Serializable]
public class Choobakka
{
    public string Name { get; set; }
    public VariableList<Item> Stuff { get; set; }
}
[Serializable]
public class Item
{
    public string Name { get; set; }
    public string Value { get; set; }
}
[Serializable]
public sealed class VariableList<T> : AVariableList<T>
{
    public new ItemList<T> Items { get { return _items; } set { _items = value; } }
    public new bool IsNull { get { return Items == null; } }
    public new bool IsEmpty { get { return IsNull || Count <= 0; } }
    public new int Count { get { return IsNull ? 0 : this.Items.Count; } }
    public new string CountAsString { get { return Count.ToString(); } }
    public VariableList()
    {
        _items = new ItemList<T>();
    }
}

这就是我填写和序列化Choobakka的东西的方式

var choobakka = new Choobakka() { Name = "CHOO-BAKKA",Stuff = new VariableList<Item>()  };            
choobakka.Stuff.Items.Add( new Item() { Name = "passport",Value = "lv" } );
choobakka.Stuff.Items.Add( new Item() { Name = "wallet",Value = "50euro" } );
StringBuilder sb = new StringBuilder();
using (TextWriter tw = new StringWriter(sb))
{
    XmlSerializer xs = new XmlSerializer(typeof(Choobakka));
    xs.Serialize(tw,choobakka);
}

序列化的XML看起来像：

<Choobakka>
    <Name>CHOO-BAKKA</Name>
    <Stuff>
        <Items>
            <Item>
                <Name>passport</Name>
                <Value>lv</Value>
            </Item>
            <Item>
                <Name>wallet</Name>
                <Value>50euro</Value>
            </Item>
        </Items>
    </Stuff>
</Choobakka>

现在问题是你如何建议获得< Items>的装备标签(如果可能的话)

<Choobakka>
    <Name>CHOO-BAKKA</Name>
    <Stuff>
        <Item>
            <Name>passport</Name>
            <Value>lv</Value>
        </Item>
        <Item>
            <Name>wallet</Name>
            <Value>50euro</Value>
        </Item>
    </Stuff>
</Choobakka>

话虽如此,我无法改变VariableList< T>的结构. class,除了应用一些XML序列化属性.

这样做的原因不仅在于简化了生成的XML,还在于对SQL Server查询生成的XML进行去逐化.我有属性的想法,xsd / xslt转换……

解决方法

如果你不能改变VariableList<>,那么改变Choobaka就行了

public class Choobakka
{
    public string Name { get; set; }
    [XmlIgnore]
    public VariableList<Item> Stuff { get; set; } // we do not serialize this
    [XmlArray("Stuff")]
    public Item[] _Stuff // but this
    {
        get
        {
            // get Item[] from Stuff property somehow
            // ...

            // as test
            return new Item[] {new Item() { Name = "1",Value = "111"},new Item() { Name = "2",Value = "222"}};
        }
        set
        {
            // set Stuff property from Item[] somehow
            // ...
        }
    }
}

生产(proof)

<?xml version="1.0" encoding="utf-16"?>
<Choobakka xmlns:xsd="http://www.w3.org/2001/XMLSchema"             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <Name>CHOO-BAKKA</Name>
  <Stuff>
    <Item>
      <Name>1</Name>
      <Value>111</Value>
    </Item>
    <Item>
      <Name>2</Name>
      <Value>222</Value>
    </Item>
  </Stuff>
</Choobakka>
