LINQ- Hour 3 (LINQ to XML)

LINQ to XML

When we interact with XML using LINQ then it is known as LINQ to XML.

To work with XML in LINQ you have to add a namespace

using System.Xml.Linq.

I am taking the following xml file for an example:-

<?xml version=”1.0” encoding=”utf-8” ?>

<Techaltum>

<student Code=”101”>

        <name>isha malhotra</name>

        <id> 1 </id>

        <course> asp.net </course>

    </student>

<student Code=”102”>

        <name>Avi malhotra</name>

        <id> 2 </id>

        <course> Web Designing </course>

    </student>

<student Code=”103”>

        <name>Neha</name>

        <id> 3 </id>

        <course> Java </course>

    </student>

</Techaltum>

If I consider this xml file then in this file first line is declaration. Techaltum is an element and in student element code is attribute.

First I will discuss how to declare all these in LINQ.

Syntax of Declaration in LINQ:-

XDeclaration dec = new XDeclaration("1.0", "utf-8", "yes");
