LINQ to XML

这套机制将加快读写XML文档的效率，以及可以直接利用LINQ进行查询。

现在有一个专门的System.Xml.Linq的命名空间

            XDocument srcTree = new XDocument(
                new XComment("This is a comment"),
                new XElement("Root",
                    new XElement("Child1", "data1"),
                    new XElement("Child2", "data2"),
                    new XElement("Child3", "data3"),
                    new XElement("Child2", "data4"),
                    new XElement("Info5", "info5"),
                    new XElement("Info6", "info6"),
                    new XElement("Info7", "info7"),
                    new XElement("Info8", "info8"),
                    new XElement("Test","Chenxizhang",new XAttribute("ID",10248))
                )
            );

            Console.WriteLine(srcTree);

            XDocument doc = new XDocument(
                new XComment("This is a comment"),
                new XElement("Root",
                    from el in srcTree.Element("Root").Elements()
                    where ((string)el).StartsWith("data")
                    select el
                )
            );
            Console.WriteLine(doc);
            Console.Read();

使用命名空间的例子

            XNamespace aw = "http://www.adventure-works.com";

           XElement root = new XElement(aw + "Root",new XAttribute(XNamespace.Xmlns + "aw", "http://www.adventure-works.com"),new XElement(aw + "Child", "child content"));
            Console.WriteLine(root);

            Console.Read();
