Hello,

I'm having troubles serializing nested objects.

Currently I have :
<?xml version="1.0" encoding="utf-8"?>
<FileConfiguration xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Version>1.0</Version>
  <FileType>abc</FileType>
  <FileValue>abc.txt</FileValue>
</FileConfiguration><?xml version="1.0" encoding="utf-8"?>
<FileConfiguration xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Version>1.0</Version>
  <FileType>abc1</FileType>
  <FileValue>abc1.txt.txt</FileValue>
</FileConfiguration>

Open in new window


But need:
<?xml version="1.0" encoding="utf-8"?>
<FileConfiguration xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Files>
  <Version>1.0</Version>
  <FileType>abc</FileType>
  <FileValue>abc.txt</FileValue>
 </Files>
<Files>
  <Version>1.0</Version>
  <FileType>abc1</FileType>
  <FileValue>abc1.txt.txt</FileValue>
</Files>
</FileConfiguration>

Here is the code, I 've tried to nest a File object in FileConfiguration it turned into a mess.  Please provide some examples.  I'm not sure how to deserialize method will change as well.

using System;
using System.IO;
using System.Xml;
using System.Xml.Serialization;

namespace ConfigurationFileCreator
{
    class Program
    {
        [STAThread]
        static void Main(string[] args)
        {

            FileConfiguration c = new FileConfiguration();
            c.FileType = "abc";
            c.FileValue = "abc.txt";
            c.Version = "1.0";


            FileConfiguration c1 = new FileConfiguration();
            c1.FileType = "Climate";
            c1.FileValue = "Climate.txt";
            c1.Version = "1.0";

            // Serialize the configuration object to a file
            FileConfiguration.Serialize("C:\\Configv1.xml", c, c1);

        }
    }


    #region -- FileConfiguration Class --
   
    [Serializable]
    
    public class FileConfiguration
    {
        string _Version;
        string _FileType;
        string _FileValue;

        public FileConfiguration()
        {
            _Version = "";
            _FileType = "";
            _FileValue = "";
        }



        public static void Serialize(string file, FileConfiguration c, FileConfiguration c1)
        {
            System.Xml.Serialization.XmlSerializer xs
               = new System.Xml.Serialization.XmlSerializer(c.GetType());
            StreamWriter writer = File.CreateText(file);
            xs.Serialize(writer, c);
            xs.Serialize(writer, c1);
            writer.Flush();
            writer.Close();
        }
//        public static Configuration Deserialize(string file)
//        {
//            System.Xml.Serialization.XmlSerializer xs
//               = new System.Xml.Serialization.XmlSerializer(
//                  typeof(Configuration));
//            StreamReader reader = File.OpenText(file);
//            Configuration c = (Configuration)xs.Deserialize(reader);
//            reader.Close();
//            return c;
//        }
        public string Version
        {
            get { return _Version; }
            set { _Version = value; }
        }
        public string FileType
        {
            get { return _FileType; }
            set { _FileType = value; }
        }
        public string FileValue
        {
            get { return _FileValue; }
            set { _FileValue = value; }
        }

    }

your class should look like this to acheive what you are trying to acheive:-

class Program
    {
        static void Main(string[] args)
        {
            var configuration = new FileConfiguration();

            configuration.AddFile("some", "test", "1.0");
            configuration.AddFile("other", "test2", "2.0");

            var fStream = new FileStream(Directory.GetCurrentDirectory() + @"\test.xml", FileMode.OpenOrCreate);

            var serializer = new NetDataContractSerializer();
            serializer.Serialize(fStream, configuration);

            fStream.Close();


            Console.Read();

        }

        
    }

    [DataContract]
    class FileConfiguration
    {
        private readonly IList<File> _lstFiles;

        public FileConfiguration()
        {
            _lstFiles = new List<File>();
        }

        public void AddFile(string name, string value, string version)
        {
            _lstFiles.Add(new File(name, version, value));
        }

        [DataMember]
        public File[] Files
        {
            get { return _lstFiles.ToArray(); }
        }
    }

    [DataContract]
    class File
    {
        [DataMember]
        public string FileName { get; private set; }

        [DataMember]
        public string FileVersion { get; private set; }

        [DataMember]
        public string FileValue { get; private set; }

        public File(string name, string version, string value)
        {
            FileName = name;
            FileVersion = version;
            FileValue = value;
        }
    }
