XML LINQ
Creating an Element Using the First Prototype
using System;
using System.Linq;
using System.Collections;
using System.Collections.Generic;
using System.Xml;
using System.Xml.Linq;
public class MainClass {
public static void Main() {
XElement firstName = new XElement("FirstName", "Joe");

Casting a Node to a Different Data Type Than Its Value's Original Data Type
using System;
using System.Linq;
using System.Collections;
using System.Collections.Generic;
using System.Xml;
using System.Xml.Linq;
public class MainClass {
public static void Main() {
XElement smoker = new XElement("Smoker", "true");
Console.WriteLine(smoker);
Console.WriteLine((bool)smoker);
}
}
Different Node Value Types Retrieved via Casting to the Node Value's Type
using System;
using System.Linq;
using System.Collections;
using System.Collections.Generic;
using System.Xml;
using System.Xml.Linq;
public class MainClass {
public static void Main() {
XElement count = new XElement("Count", 12);
Console.WriteLine(count);
Console.WriteLine((int)count);
XElement smoker = new XElement("Smoker", false);
Console.WriteLine(smoker);
Console.WriteLine((bool)smoker);
XElement pi = new XElement("Pi", 3.1415926535);
Console.WriteLine(pi);
Console.WriteLine((double)pi);
}
}
Casting an Element to Its Value's Data Type Outputs the Value
using System;
using System.Linq;
using System.Collections;
using System.Collections.Generic;
using System.Xml;
using System.Xml.Linq;
public class MainClass {
public static void Main() {
XElement name = new XElement("Name", "Joe");
Console.WriteLine(name);
Console.WriteLine((string)name);
}
}
Immediate Execution of the XML Tree Construction
using System;
using System.Linq;
using System.Collections;
using System.Collections.Generic;
using System.Xml;
using System.Xml.Linq;
public class MainClass {
public static void Main() {
string[] names = { "J", "P", "G", "P" };
XElement xNames = new XElement("Beatles",
from n in names
select new XElement("Name", n));
names[3] = "R";
Console.WriteLine(xNames);
}
}
Calling the ToString Method on an Element Produces the XML Tree
using System;
using System.Linq;
using System.Collections;
using System.Collections.Generic;
using System.Xml;
using System.Xml.Linq;
public class MainClass {
public static void Main() {
XElement name = new XElement("Name", "Joe");
Console.WriteLine(name.ToString());
}
