Difference between XElement and XDocument

XDocument represents a whole XML document. It is normally composed of a number of elements.
XElement represents an XML element

Both are the classes defined by System.Xml.Linq namespace

XElement class
represents an XML fragment
XDocument class represents an entire XML document with all associated meta-data.


XDocument d = new XDocument(
      new XComment("hello"),
      new XElement("book",
              new XElement("bookname", "ASP.NET"),
             new XElement("authorname", "techmedia"),

What is Dot net Framework ?

DOT NET is an integral part of many applications running on Windows and provides common functionality for those applications to run.The DOT NET Framework  is a software framework developed by Microsoft. DOT NET is a general-purpose software development platform, similar to Java. The Microsoft .NET Framework is   available with several Microsoft Windows operating systems.It includes a large library of pre-coded solutions to common programming problems, a runtime or virtual machine that manages the execution of programs written specifically for the framework, and a set of tools for configuring and building applications. The .NET Framework is a key Microsoft offering and is intended to be used by most new applications created for the Windows platform.At its core is a virtual machine that turns intermediate language (IL) into machine code. High-level language compilers for C#, VB.NET and C++ are provided to turn source code into IL. C# is a new programming language, very similar to Java. An extensive class library is included, featuring all the functionality one might expect from a contempory development platform - windows GUI development (Windows Forms), database access (ADO.NET), web development (ASP.NET), web services, XML etc.

LINQ Restriction Operators example in CSharp

This example gives an idea to you how to use where clause in the LINQ. Here we have nums array which having some integer values.We are writing LINQ for fetching numbers less than 5.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace LinqExamples
    class Program
        static void Main(string[] args)
            int[] nums = { 1, 2, 3, 4, 5, 6, 7, 8 };

            var numbersLessThan5=from n in nums
                                 where n<5 select n;

            foreach (int num in numbersLessThan5)
                Console.WriteLine(num); //output: 1 2 3 4
