Description

Generating an XML Tree with a LINQ Query

Demo

using System;
using System.Linq;
using System.Xml.Linq;
using System.Collections.Generic;

class Program/*w ww .  ja v  a  2 s .  c o m*/
{
    static void Main(string[] args){
      Book[] Books = new[] {
        new Book {FirstName = "Joe", LastName = "Ruby", ParticipantType = ParticipantTypes.Author},
        new Book {FirstName = "PHP", LastName = "Python", ParticipantType = ParticipantTypes.Editor}
      };

      XElement xBooks =
         new XElement("Books",
                       Books.Select(p =>
                         new XElement("Book",
                           new XAttribute("type", p.ParticipantType),
                           new XElement("FirstName", p.FirstName),
                           new XElement("LastName", p.LastName))));

      Console.WriteLine(xBooks);
    }
}
enum ParticipantTypes
{
          Author = 0,
          Editor
}

class Book
{
          public string FirstName;
          public string LastName;
          public ParticipantTypes ParticipantType;
}

Result

The following code creates an array of Book objects named Books.

Next, the code queries the values from the Books array using the Select operator and generates a Book element for each, using the members of the element of the array.
