Add Information To XML file in C#

Say I have an XML Document that looks like this:

 <BOOK>
  <NAME>Home</NAME>
  <ISBN>0-943396-04-2</ISBN>
  <PRICE>$0.82</PRICE>
 </BOOK>

And I have a program that has the purpose of allowing the user to add another book to the list... what code would I put on the Button I have titled "Add Book" to make it add another set of information?

So the end product would look like this:

 <BOOK>
  <NAME>Home</NAME>
  <ISBN>0-943396-04-2</ISBN>
  <PRICE>$0.82</PRICE>
 </BOOK>
 <BOOK>
  <NAME>Work</NAME>
  <ISBN>0-85131-041-9</ISBN>
  <PRICE>$0.99</PRICE>
 </BOOK>

I am using Microsoft Visual C# 2010 Express, if that helps.

firstly youll need to put a container around your books list so

<BOOKS>
<BOOK>
  <NAME>Home</NAME>
  <ISBN>0-943396-04-2</ISBN>
  <PRICE>$0.82</PRICE>
 </BOOK>
</BOOKS>

Then you'll need to parse it with something are you storing it in a file? if so then 

XElement.Load(filename);

otherwise you can parse a string

XElement el = XElement.Parse(@"<BOOKS><BOOK>
  <NAME>Home</NAME>
  <ISBN>0-943396-04-2</ISBN>
  <PRICE>$0.82</PRICE>
 </BOOK></BOOKS>");

then create a and add a new book 

var newBook = new XElement("BOOK", new[]
{ 
    new XElement("NAME", "thename"), 
    new XElement("ISBN", "isbn"), 
    new XElement("PRICE", ".71") 
});
el.Add(newBook);

and save it if you need to 

el.Save(filename)

Reformatted comment below;

var el = XElement.Load("Ops.xml");
var newOp = new XElement("Operation", new[] {
    new XElement("Operation Name", textBox2.Text), 
    new XElement("Operation Date", dateTimePicker1.Value)
});
el.Add(newOp);
