Serializing and Deserializing Object as XML Data Using XmlSerializer

List<Product> b = (List<Product>)serializer.Deserialize(tr);

tr.Close();
Foreach (Product product in b)
{
Response.Write(product.Sections[0].Name + ",");
Response.Write(product.Sections[1].Name);
}
}

Step 6: The List has no collection:

<?xml version="1.0" encoding="utf-8"?>
<ArrayOfProduct xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Product />
</ArrayOfProduct>

Step 7: Copy and Paste code snippet:

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

namespace SampleApplication
{
public partial class SerializeMe : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Serialize();
DeSerialize();
}

//serialize
private void Serialize()
{
//Creating Custom List
List<Product> list = GetProductList();

//Creating XmlSerializer.
XmlSerializer serializer = new XmlSerializer(typeof(List<Product>));

//Creating text writer for xml data
TextWriter tw = new StreamWriter(Server.MapPath("book1.xml"));

//Convert the XML to List
serializer.Serialize(tw, list);
tw.Close();
}
//Deserialize
public void DeSerialize()
{
XmlSerializer serializer = new XmlSerializer(typeof(List<Product>));
TextReader tr = new StreamReader(Server.MapPath("book1.xml"));
List<Product> b = (List<Product>)serializer.Deserialize(tr);
tr.Close();

foreach (Product product in b)
{
Response.Write(product.Sections[0].Name + ",");
Response.Write(product.Sections[1].Name);
}
}
public List<Product> GetProductList()
{
List<Product> list = new List<Product>();

Product product = new Product(new Section[3]);
product.Sections[0] = new Section("1", new Header[3]);
product.Sections[0].Headers[0] = new Header("P1", "C1", "T1");

product.Sections[0].Headers[1] = new Header("P2", "C2", "T2");
product.Sections[1] = new Section("2", new Header[3]);
product.Sections[1].Headers[0] = new Header("P1", "C1", "T1");
product.Sections[1].Headers[1] = new Header("P2", "C2", "T2");

list.Add(product);
return list;
}
}
public class Product
{
public Product()
{
}
public Product(Section[] sections)
{
this.Sections = sections;
}
public Section[] Sections;
}

public class Section
{
public Section()
{
}
public Section(string name, Header[] headers)
{
this.Name = name;
this.Headers = headers;
}
[XmlAttribute]
public string Name;
public Header[] Headers;
}
public class Header
{
public Header()
{
}
public Header(string propertyName, string className, string text)
{
this.PropertyName = propertyName;
this.ClassName = className;
this.Text = text;
}
[XmlAttribute]
public string PropertyName;

[XmlAttribute]
public string ClassName;

[XmlText]
public string Text;
}
}
