you need to create a class named AddressDetails in your windows application

public class AddressDetails
{
public int HouseNo { get; set; }
public string StreetName { get; set; }
public string City { get; set; }
}

    private void button1_Click(object sender, EventArgs e)
{
//Serialization of object to XML form
AddressDetails details = new AddressDetails();
details.HouseNo = 4;
details.StreetName = "Rohini";
details.City = "Delhi";
            Serialize(details);
MessageBox.Show("Completed");
}

private void button2_Click(object sender, EventArgs e)
{
//Deserialization of XML to object form
XmlSerializer deserializer = new XmlSerializer(typeof(AddressDetails));
TextReader reader = new StreamReader(@"C:\Test\Xml.xml");
object obj = deserializer.Deserialize(reader);
            AddressDetails XmlData = (AddressDetails)obj;
reader.Close();
string data = string.Empty;
data=String.Format("House No :{0}", XmlData.HouseNo) + Environment.NewLine;
data = data + String.Format("StreetName :{0}", XmlData.StreetName) + Environment.NewLine;
data = data + String.Format("City :{0}", XmlData.City) + Environment.NewLine;
MessageBox.Show(data);
}

public static void Serialize(AddressDetails details)
{
XmlSerializer serializer = new XmlSerializer(typeof(AddressDetails));
using (TextWriter writer = new StreamWriter(@"C:\Test\Xml.xml"))
{
serializer.Serialize(writer, details);
}
}
}

I created the class file also but I got the error which I have highlited in block letters

Hi,
Try like this

public static void Serialize(List list)
{
XmlSerializer xmlser = new XmlSerializer(typeof(List<Employee>));
using (StreamWriter stmw = new StreamWriter(@"D:\sxml.xml"))
{
xmlser.Serialize(stmw, list);
}
}
