class Test
{
[STAThread]static void Main(string[] args)
{
ItemList myList = new ItemList();
myList.AddItem(new Item(“first”, 1));
myList.AddItem(new Item(“second”, 2));
myList.AddItem(new Item(“third”, 3));
// Serialization
XmlSerializer xs = new XmlSerializer(typeof(ItemList));
TextWriter tw = new StreamWriter(@”c:\list.xml”);
xs.Serialize(tw, myList);
tw.Close();
// Deserialization
ItemList newList;
TextReader tr = new StreamReader(@”c:\list.xml”);
newList = (ItemList)xs.Deserialize(tr);
tr.Close();
}
}
[XmlRoot("itemList")]
public class ItemList
{
private ArrayList listItem;
public ItemList()
{
listItem = new ArrayList();
}
[XmlElement("item")]
public Item[] Items
{
get
{
Item[] items = new Item[listItem.Count];
listItem.CopyTo(items);
return items;
}
set
{
if (value == null) return;
Item[] items = (Item[])value;
listItem.Clear();
foreach (Item item in items)
{
listItem.Add(item);
}
}
}
public int AddItem(Item item)
{
return listItem.Add(item);
}
}
public class Item
{
[XmlAttribute("name")] public string Name; [XmlAttribute("id")]
public int Id;
public Item(string name, int id)
{
Name = name;
Id = id;
}
}
Resulting XML:
<itemList>
<item name=“first“ id=“1“/>
<item name=“second“ id=“2“/>
<item name=“third“ id=“3“/>
</itemList>
