How to override xml element name for collection elements using XmlAttributeOverrides?

I've got a very basic object object model that is being serialized by the System.Xml.XmlSerialization stuff. I need to use the XmlAttributeOverrides functionality to set the xml element names for a collection of child elements.

public class Foo{
  public List Bars {get; set; }
}

public class Bar {
  public string Widget {get; set; }
}

using the standard xml serializer, this would come out as

 <Foo>
  <Bars>
    <Bar>...</Bar>
  </Bars>
 </Foo>

I need to use the XmlOverrideAttributes to make this say

 <Foo>
  <Bars>
    <SomethingElse>...</SomethingElse>
  </Bars>
 </Foo>

but I can't seem to get it to rename the child elements in the collection... i can rename the collection itself... i can rename the root... not sure what i'm doing wrong.

here's the code I have right now:

XmlAttributeOverrides xOver = new XmlAttributeOverrides(开发者_JAVA技巧);

var bars = new XmlElementAttribute("SomethingElse", typeof(Bar));
var elementNames = new XmlAttributes();
elementNames.XmlElements.Add(bars);
xOver.Add(typeof(List), "Bars", elementNames);

StringBuilder stringBuilder = new StringBuilder();
StringWriter writer = new StringWriter(stringBuilder);
XmlSerializer serializer = new XmlSerializer(typeof(Foo), xOver);
serializer.Serialize(writer, someFooInstance);

string xml = stringBuilder.ToString();

but this doesn't change the name of the element at all... what am I doing wrong?

thanks

To do that you want [XmlArray] and [XmlArrayItem] (ideally both of to make it explicit):

using System.Collections.Generic;
using System.IO;
using System.Xml.Serialization;
public class Foo {
    public List<Bar> Bars { get; set; }
}  
public class Bar {
    public string Widget { get; set; }
}
static class Program {
    static void Main() {
        XmlAttributeOverrides xOver = new XmlAttributeOverrides();
        xOver.Add(typeof(Foo), "Bars", new XmlAttributes {
            XmlArray = new XmlArrayAttribute("Bars"),
            XmlArrayItems = {
                new XmlArrayItemAttribute("SomethingElse", typeof(Bar))
            }
        });
        XmlSerializer serializer = new XmlSerializer(typeof(Foo), xOver);
        using (var writer = new StringWriter()) {
            Foo foo = new Foo { Bars = new List<Bar> {
                new Bar { Widget = "widget"}
            }};
            serializer.Serialize(writer, foo);
            string xml = writer.ToString();
        }            
    }
}

Derick,

This worked for me - not sure if it's a suitable answer for you or not:

public class Foo
{
    [XmlArrayItem(ElementName = "SomethingElse")]
    public List<Bar> Bars { get; set; }
}
