Serialize an object to XElement and Deserialize it in memory

Question

I want to serialize an object to XML, but I don\'t want to save it on the disk. I want to hold it in a XElement variable (for using with LINQ), and then Deserialize back to

Answer 1

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
