Serialize an object to XElement and Deserialize it in memory

You can use these two extension methods to serialize and deserialize between XElement and your objects.

public static XElement ToXElement<T>(this object obj){    using (var memoryStream = new MemoryStream())    {        using (TextWriter streamWriter = new StreamWriter(memoryStream))        {            var xmlSerializer = new XmlSerializer(typeof(T));            xmlSerializer.Serialize(streamWriter, obj);            return XElement.Parse(Encoding.ASCII.GetString(memoryStream.ToArray()));        }    }}public static T FromXElement<T>(this XElement xElement){        var xmlSerializer = new XmlSerializer(typeof(T));        return (T)xmlSerializer.Deserialize(xElement.CreateReader());}

USAGE

XElement element = myClass.ToXElement<MyClass>();var newMyClass = element.FromXElement<MyClass>();

You can use XMLSerialization

XML serialization is the process of converting an object's public properties and fields to a serial format (in this case, XML) for storage or transport. Deserialization re-creates the object in its original state from the XML output. You can think of serialization as a way of saving the state of an object into a stream or buffer. For example, ASP.NET uses the XmlSerializer class to encode XML Web service messages

and XDocument Represents an XML document to achieve this

   using System;using System.Linq;using System.Xml;using System.Xml.Linq;using System.Xml.Serialization;namespace ConsoleApplication5{  public class Person  {    public int Age { get; set; }    public string Name { get; set; }  }  class Program  {    static void Main(string[] args)    {      XmlSerializer xs = new XmlSerializer(typeof(Person));      Person p = new Person();      p.Age = 35;      p.Name = "Arnold";      Console.WriteLine("\n Before serializing...\n");      Console.WriteLine(string.Format("Age = {0} Name = {1}", p.Age,p.Name));      XDocument d = new XDocument();      using (XmlWriter xw = d.CreateWriter())        xs.Serialize(xw, p);      // you can use LINQ on elm now      XElement elm = d.Root;      Console.WriteLine("\n From XElement...\n");      elm.Elements().All(e => { Console.WriteLine(string.Format("element name {0} , element value {1}", e.Name, e.Value)); return true; });      //deserialize back to object      Person pDeserialized = xs.Deserialize((d.CreateReader())) as Person;      Console.WriteLine("\n After deserializing...\n");      Console.WriteLine(string.Format("Age = {0} Name = {1}", p.Age, p.Name));      Console.ReadLine();    }  }}

and here is output

(Late answer)

Serialize:

var doc = new XDocument();var xmlSerializer = new XmlSerializer(typeof(MyClass));using (var writer = doc.CreateWriter()){    xmlSerializer.Serialize(writer, obj);}// now you can use `doc`(XDocument) or `doc.Root` (XElement)

Deserialize:

MyClass obj; using(var reader = doc.CreateReader()){    obj = (MyClass)xmlSerializer.Deserialize(reader);}
