I've got a parent object that is a collection and it in turn is
hosting 2 child objects.
My searlization has worked perfectly to plan in as much that I wanted
to dictate the names of the objects and properties via XMLatrributes
with a prefix of "THE_.."....except for the name of the child objects.
This should say THE_NEW_Child but instead still persist in saying
"NewChild" (Child properties are as planned)

What's the solution?

Here's the code which is quite simple and compiles as 3 modules called
ConsolePogram.CS, New_Parent.CS and New_Child.CS:-

1/ ConsolePogram.CS:-

using System;
using System.Collections.Generic;
using System.Text;
using System.Xml.Serialization;

namespace Serialization
{
   class Program
   {
       static void Main(string[] args)
       {
           // Create parent (collection) & child object
           New_Parent p = new New_Parent();
           NewChild c = new NewChild();

           // Add 2 children to parent collection
           c.A = "first instance of a";
           c.B = "first instance of b";
           p.Add( c);

           c.A = "scond instance of a";
           c.B = "scond instance of b";
           p.Add (c);

           // Serialize and display
           System.Xml.Serialization.XmlSerializer x = new
System.Xml.Serialization.XmlSerializer(p.GetType());
           x.Serialize(Console.Out, p);

           // Pause the screen
           Console.ReadLine();
       }
   }
}

2/ New_Parent.CS:-
using System;
using System.Collections.Generic;
using System.Text;
using System.Xml.Serialization;

namespace Serialization
{
   [XmlRootAttribute("THE_NEW_Parent", Namespace = "", IsNullable =
false)]
   public class New_Parent : List<NewChild>
   {

   }
}

3/ New_Child.CS:-
using System;
using System.Collections.Generic;
using System.Text;
using System.Xml.Serialization;

namespace Serialization
{
   //QUESTION - hOW DO I OVERRIDE NewChild class name because this
   // following XML attribute doesn't do it!
   [XmlRootAttribute("THE_NEW_Child", Namespace = "", IsNullable =
false)]
   public class NewChild
   {
       private String a;

       [XmlAttribute("THE_A")]
       public String A
       {
           get { return a; }
           set { a = value; }
       }

       private String b;

       [XmlAttribute("THE_B")]
       public String B
       {
           get { return b; }
           set { b = value; }
       }

   }
}
