has only two constructors:

The second of these constructors is used in the previous example and in the majority of cases s to an XML element, you If you want to add two or more can write the following lines of code:

Most of the important properties and methods of and are used primarily in the context of querying data, so I will show you how to use them in that section of this chapter For now, it is important only that you understand how to use their constructors to create XML nodes

Creating an XML Document The class is remarkably exible, and it will t your needs in many is similar to cases However, a second class called unless you have a use for one There is no reason to create an eleTypically, those uses would include a desire to explicitly access the ment in your XML tree, or wanting to include an XML declaration in a document you are creating Here is code that creates a simple XML document:

You can print the output from this document to the console with the following line of code:

Creating an XML Declaration An XML declaration is found on the rst line of this simple XML document:

To add this node to your XML le, you must use an cannot handle declarations As shown in Listing 132, LINQ to XML makes it easy for you to create and con gure the various sections of an XML declaration The code shown in Listing 132 includes an XML declaration, an XML comment, and an XML attribute Listing 133 shows the simple XML le produced by this code

A single nested statement, written in the declarative style, is used to create this XML document If you indent your code properly, this kind of statement is easy to use, because it mirrors the structure of the document you want to create Later in this chapter, I will show you how to create a similar document from a series of discrete statements However, the declarative style shown in this example is preferred and is generally held up as one of the attractions of the LINQ to XML API statements to display the outNote that you need to use two put from the code in Listing 132 in its entirety The rst statement writes

I can t think of anything useful to say about the constructors for these simple classes other than they are easy to use and have obvious utilitarian value Simply lift the code directly from Listing 132, and insert it into your own programs This excerpt from Listing 132 includes examples of how to use the fth constructor: overload of the
Recall that this fth overload of the
constructor looks like this:
This is a deceptively powerful line of code The unusual type called allows you to pass an array of from 0 to n classes that derive from This means, in effect, that you can pass an array of any type type of object in this parameter In particular, you can pass in a lengthy sequence and constructors like those shown in this example of This is a form of compiler magic that enables LINQ to support the declarative style of programming
