XML can also be written in .net through XmlDocument and XDocument. XmlDocument is the standard XML writing class originally supported. Now the extended XDocument class is more convenient to use. Let’s use the XDocument class to write an XML file.

Writing steps:

(1) First create an XDocument object

(2) Set the XML document definition

(3) Create the root node

(4) Loop List collection creates child nodes (person class is used here to enter data)

(5) Save to file

<pre name="code" class="csharp"> List<person> list = new List<person>();
<span style="font-family:Microsoft YaHei;font-size:18px;">            
list.Add(new person() { name = "IstarI", age = 20, Email = "1061399756@qq.com" });
            list.Add(new person() { name = "Orange", age = 20, Email = "521@qq.com" });

            //1、创建一个XDocument对象
            XDocument xDoc = new XDocument();
            XDeclaration XDec = new XDeclaration("1.0", "utf-8","no");
            //设置xml的文档定义
            xDoc.Declaration = XDec;

            //2、创建根节点
            XElement rootElement = new XElement("List");
            xDoc.Add(rootElement);

            //3、循环list集合创建子节点
            for (int i = 0; i <list.Count; i++)
            {
                //为每个person对象创建一个person元素
                XElement xpersonElement = new XElement("person");
                xpersonElement.SetAttributeValue("id", (i + 1).ToString());
                xpersonElement.SetElementValue("name", list[i].name);
                xpersonElement.SetElementValue("age", list[i].age.ToString ());
                xpersonElement.SetElementValue("Email", list[i].Email);
                rootElement.Add(xpersonElement);
            }
            //4、保存到文件
            xDoc.Save("List1.xml");
            MessageBox.Show("OK");</span>
