See if Richard's excellent response, and this code ... gives you some ideas:
using System;
using System.IO;
using System.Xml.Serialization;

namespace TextToClasses
{
    public class BaseClass
    {
        public class Data
        {
            public int Data1;
            public int Data2;
            public string Data3;

            public Data()
            {
            }

            public Data(int data1, int data2, string data3)
            {
                Data1 = data1;
                Data2 = data2;
                Data3 = data3;
            }
        }

        public Data TheData;

        public bool Save(string Filename, Data data)
        {
            var xs = new XmlSerializer(data.GetType());

            using (TextWriter sw = new StreamWriter(Filename))
            {
                xs.Serialize(sw, data);
            }

            return File.Exists(Filename);
        }

        public Data Load(string Filename, Type type)
        {
            Data rslt;

            var xs = new XmlSerializer(type);

            using (var sr = new StreamReader(Filename))
            {
                rslt = (Data) xs.Deserialize(sr);
            }

            return rslt;
        }
    }

    public class DerivedClass : BaseClass
    {
        public class DerivedData : BaseClass.Data
        {
            public int Data4;

            public DerivedData()
            {
            }

            public DerivedData(int data4, int data1, int data2, string data3) : base(data1, data2, data3)
            {
                Data4 = data4;
            }
        }
    }
}
Sample usage:
BaseClass bc = new BaseClass();
bc.TheData = new BaseClass.Data(1,1,"BaseString");

bc.Save(@"C:\Users\test_user\Desktop\Basedata.xml", bc.TheData);

var bcdata = bc.Load(@"C:\Users\test_user\Desktop\Basedata.xml", bc.TheData.GetType());

DerivedClass dc = new DerivedClass();
dc.TheData = new DerivedClass.DerivedData(4, 2, 2, "DerivedString");

dc.Save(@"C:\Users\test_user\Desktop\Deriveddata.xml", dc.TheData);

var dcdata = dc.Load(@"C:\Users\test_user\Desktop\Deriveddata.xml", dc.TheData.GetType());
I am sure this can be improved Smile | :)
