How would I annotate this .net Type to serialise/deserialise to/from the following XML, using System.Xml.Serialization

Question

The type:

public class Foo
{
    public string Bar { get; set; }
    public string Fred { get; set; }
}

The instance

Foo x = new Foo { Bar = "Hi", Fred = "hey yourself" };

The XML:

<Foo>
   <Bar>Hi</Bar>
   <John>                         <!-- Note extra layer -->
       <Fred>hey there</Fred>
   </John>
</Foo>

Note the extra John tag, but without create a special type for John . If I cannot annotate it, what how can I programmatically control the serialisation process.

Try this :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
using System.Runtime;
using System.Runtime.InteropServices;

namespace ConsoleApplication42
{
    class Program
    {

        static void Main(string[] args)
        {

            Foo x = new Foo { Bar = "Hi", Fred = "hey yourself" };
            //<Foo>
            //   <Bar>Hi</Bar>
            //   <John>                         <!-- Note extra layer -->
            //       <Fred>hey there</Fred>
            //   </John>
            //</Foo>

            XElement foo = new XElement("Foo", new object[] {
                new XElement("Bar", x.Bar),
                new XElement("John", new XElement("Fred", x.Fred))
            });

        }
    }
    public class Foo
    {
        public string Bar { get; set; }
        public string Fred { get; set; }
    }

}
