C#用XDocument操作XML

{
	//创建Person类
	  public class Person
    {
        private string _name;
        private int _age;
        private char _gender;
        private int _salary;

        public string Name { get => _name; set => _name = value; }
        public int Age { get => _age; set => _age = value; }
        public char Gender { get => _gender; set => _gender = value; }
        public int Salary { get => _salary; set => _salary = value; }
        //带参数的构造器
       public Person(string na,int ag,char ge,int sa)
        {
            this._name = na;
            this._age = ag;
            this._gender = ge;
            this._salary = sa;
        }
        //无参数的构造器
        public Person()
        {

        }

    }
    
    class Program
    {
        static void Main(string[] args)
        {
         
            List<Person> persons = new List<Person>() { new Person("李刚",23,'男',10000),
            new Person("张三",45,'女',3400),
            new Person("李四",67,'男',4500),
            new Person("王五",43,'男',9800)};

            #region xDoc来操作xml文件
            XDocument xdoc = new XDocument();
            XDeclaration xdec = new XDeclaration("1.0", "utf-8", "yes");
            xdoc.Declaration = xdec;
            //根节点
            XElement xElem = new XElement("List");
            
            for (int i=0;i<persons.Count;i++)
            {
                //创建一个person元素
                XElement xpersonElement = new XElement("Person");
                //把person挂在根节点上
                xElem.Add(xpersonElement);
                //创建name元素
                XElement nameElement = new XElement("name",persons[i].Name);
                xpersonElement.Add(nameElement);
                //创建age元素
                XElement ageElement = new XElement("age", persons[i].Age.ToString());
                xpersonElement.Add(ageElement);
                //创建gender元素
                XElement genderElement = new XElement("gender", persons[i].Gender.ToString());
                genderElement.Add(genderElement);
                //创建salary元素
                XElement salaryElement = new XElement("salary", persons[i].Salary.ToString());
                xpersonElement.Add(salaryElement);
            }
            //将根节点挂在xdoc上
            xdoc.Add(xElem);
            xdoc.Save("person.xml");
            #endregion
            Console.WriteLine("写入成功！");
            Console.ReadKey();


        }
    }
}

创建的效果如下：

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<List>
  <Person>
    <name>李刚</name>
    <age>23</age>
    <salary>10000</salary>
  </Person>
  <Person>
    <name>张三</name>
    <age>45</age>
    <salary>3400</salary>
  </Person>
  <Person>
    <name>李四</name>
    <age>67</age>
    <salary>4500</salary>
  </Person>
  <Person>
    <name>王五</name>
    <age>43</age>
    <salary>9800</salary>
  </Person>
</List>
