Csharp/C Sharp/XML LINQ/XNamespace

Create Where an XName Object Is Created and Specify Namespace

 
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() {
        XNamespace ns = "http://www.nfex.ru/Books";
        XElement xBookParticipant = new XElement(ns + "Book");
        Console.WriteLine(xBookParticipant);
    }
}

Specifying a Namespace Prefix

 
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() {
        XNamespace nameSpace = "http://www.nfex.ru";
        XElement xBooks =
        new XElement(nameSpace + "Books",
          new XAttribute(XNamespace.Xmlns + "linqdev", nameSpace),
        new XElement(nameSpace + "BookParticipant"));
        Console.WriteLine(xBooks.ToString());
    }
}

Use Linq to create XML document with a Namespace Specified

 

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() {
        XNamespace nameSpace = "http://www.nfex.ru";
        XElement xBooks =
        new XElement(nameSpace + "Books",
        new XElement(nameSpace + "Book",
        new XAttribute("type", "Author"),
        new XElement(nameSpace + "FirstName", "J"),
        new XElement(nameSpace + "LastName", "R")),
        new XElement(nameSpace + "Book",
       new XAttribute("type", "Author"),
       new XElement(nameSpace + "FirstName", "E"),
       new XElement(nameSpace + "LastName", "B")));
        Console.WriteLine(xBooks.ToString());
    }
}
