.net XML序列化：如何指定数组的根元素和子元素名称

Question

Consider the following serializable classes:

class Item {...}
class Items : List<Item> {...}
class MyClass
{
   public string Name {get;set;}
   public Items MyItems {get;set;}
}

I want the serialized output to look like:

<MyClass>
    <Name>string</Name>
    <ItemValues>
        <ItemValue></ItemValue>
        <ItemValue></ItemValue>
        <ItemValue></ItemValue>
    </ItemValues>
</MyClass>

Notice the element names ItemValues and ItemValue doesn't match the class names Item and Items, assuming I can't change the Item or Items class, is there any why to specify the element names I want, by modifying the MyClass Class?

Answer 1

public class MyClass
{
    public string Name {get;set;}
    [XmlArray("ItemValues")]
    [XmlArrayItem("ItemValue")]
    public Items MyItems {get;set;}
}

Answer 2

You might want to look at " How to: Specify an Alternate Element Name for an XML Stream "

That article discusses using the XmlElementAttribute 's ElementName to accomplish this.

Answer 3

You could also consider using Linq to Xml to construct your XML from your class. Something like

XElement element = new XElement(
    "MyClass",
    new XElement("Name", myClass.Name),
    new XElement(
        "ItemValues",
        from item in myClass.Items
        select new XElement(
            "ItemValue",
            new XElement("Foo", item.Foo))));

Which would create

<MyClass>
  <Name>Blah</Name>
  <ItemValues>
    <ItemValue>
      <Foo>A</Foo>
    </ItemValue>
    <ItemValue>
      <Foo>B</Foo>
    </ItemValue>
  </ItemValues>
</MyClass>
