Creating an Attribute and Adding It to Its Element

 
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 xBookParticipant = new XElement("BookParticipant"); 
        XAttribute xAttribute = new XAttribute("type", "Author"); 
        xBookParticipant.Add(xAttribute);
        Console.WriteLine(xBookParticipant);
    }
}

Creating an Attribute with Functional 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() {
        XElement xBookParticipant = new XElement("BookParticipant",
                     new XAttribute("type", "Author"));
        Console.WriteLine(xBookParticipant);
    }
}

Using the LINQ to XML API to Create an XML Document

 
using System;

using System.Collections;
using System.Collections.Generic;
using System.Xml;
using System.Xml.Linq;
public class MainClass {
    public static void Main() {
        XElement xElement =
          new XElement("Books",
          new XElement("Book",
          new XAttribute("type", "Author"),
          new XElement("FirstName", "J"),
          new XElement("LastName", "R")));
        Console.WriteLine(xElement.ToString());
    }
}
