Answer 1

Your options will be:

1. XML - one of your tags actually
2. Database
3. Binary File

Store the objects and the read them in your code.

Write XML code example:

public void WriteXML()
{
    Book overview = new Book();
    overview.title = "Serialization Overview";
    System.Xml.Serialization.XmlSerializer writer = 
        new System.Xml.Serialization.XmlSerializer(typeof(Book));

    System.IO.StreamWriter file = new System.IO.StreamWriter(
        @"c:\temp\SerializationOverview.xml");
    writer.Serialize(file, overview);
    file.Close();
}

Read XML code example:

public void Read(string  fileName)
{
    XDocument doc = XDocument.Load(fileName);

    foreach (XElement el in doc.Root.Elements())
    {
        Console.WriteLine("{0} {1}", el.Name, el.Attribute("id").Value);
        Console.WriteLine("  Attributes:");
        foreach (XAttribute attr in el.Attributes())
            Console.WriteLine("    {0}", attr);
        Console.WriteLine("  Elements:");

        foreach (XElement element in el.Elements())
            Console.WriteLine("    {0}: {1}", element.Name, element.Value);
    }
}
