Serialize and DeSerialize of Class object to xml and Xml to Class

In this article we are going to see , how to serialize the class object to XML and De-Serialize the xml object to Class. For That Let we take a Example that , Employee file List ,which will maintain the information about employees and there projects.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml.Serialization;
using System.IO;
using System.Reflection;

namespace ConsoleApplication8
{
    class Program
    {
        static void Main(string[] args)
        {
            Serialize();
            EmployeeFile EmpFile = DeSerialize();
            foreach (Employee emp in EmpFile.Employees)
                Console.WriteLine("Employee Name " + emp.Name);
            Console.Read();
        }

        static EmployeeFile DeSerialize()
        {
            XmlSerializer serialize=new XmlSerializer(typeof(EmployeeFile));
            TextReader reader=new StreamReader(@"D:\EmployeeFileList.xml",true);
            return (EmployeeFile)serialize.Deserialize(reader);
        }

        static void Serialize()
        {
            EmployeeFile employeefilelist = new EmployeeFile();
            Employee emp1 = new Employee();
            emp1.Name = "Suresh";
            emp1.Address = "chennai";
            emp1.Age = 22;
            emp1.Projects.Add(new Project() { Domain = "Java", Name = "Encryption Handling" });
            emp1.Projects.Add(new Project() { Domain = "DotNet", Name = "Automatic ReCycling" });

            Employee emp2 = new Employee();
            emp2.Name = "Rajesh";
            emp2.Address = "Chennai";
            emp2.Age = 25;
            emp2.Projects.Add(new Project() { Domain = "DotNet", Name = "Custom Controls" });
            emp2.Projects.Add(new Project() { Domain = "PHP", Name = "Faster Browsing" });


            employeefilelist.Employees.Add(emp1);
            employeefilelist.Employees.Add(emp2);

            XmlSerializer serialize = new XmlSerializer(typeof(EmployeeFile));
            TextWriter writer = new StreamWriter(@"D:\EmployeeFileList.xml", true);
            serialize.Serialize(writer, employeefilelist);
            writer.Close();

        }
     
    }

    [Serializable]
    public class Project
    {
        private string name;
        [XmlAttribute]
        public string Name
        {
            set { name = value; }
            get { return name; }
        }

        private string domain;

        [XmlAttribute]
        public string Domain
        {
            set
            {
                domain = value;
            }
            get
            {
                return domain;
            }
        }
    }

    [Serializable]
    public class Employee
    {
        private string name;
       
        [XmlAttribute]
        public string Name
        {
            set { name = value; }
            get { return name; }
        }

        private string address;

        [XmlAttribute]
        public string Address
        {
            set { address = value; }
            get { return address; }
        }

        private int age;
       
        [XmlAttribute]
        public int Age
        {
            set { age = value; }
            get { return age; }
        }

        private List<Project> projects = new List<Project>();

        public List<Project> Projects
        {
            set { projects = value; }
            get { return projects; }
        }

    }

    [Serializable]
    public class EmployeeFile
    {
        private List<Employee> employees = new List<Employee>();

        public List<Employee> Employees
        {
            set { employees = value; }
            get { return employees; }
        }

    }

}


 Output :

Serialize an Xml is Formed in Location D:\EmploeeeFileList.xml



DeSerialize the Xml and save the data in employeefile class object print the Employee name in Console:

Employee Name Suresh
Employee Name Rajesh


This article will explain you how to convert the xml to class object and from class object to xml.
