Working with LINQ to XML

LINQ to XML is a LINQ provider that allows you to query and manipulate XML.

Generating XML using LINQ to XML

Let's create a method to convert the Products table into XML:

1. In the LinqWithEFCore project, at the top of Program.cs, import the System.Xml.Linq namespace.
2. At the bottom of Program.cs, create a method to output the products in XML format, as shown in the following code:

   static void OutputProductsAsXml()
   {
     using (Northwind db = new())
     {
       Product[] productsArray = db.Products.ToArray();
       XElement xml = new("products",
         from p in productsArray
         select new XElement("product",
           new XAttribute("id",  p.ProductId),
           new XAttribute("price", p.UnitPrice),
          new XElement("name", p.ProductName)));
       WriteLine(xml.ToString());
     }
   }
   

3. In Program.cs, comment the previous method call and call OutputProductsAsXml.
4. Run...
