employee.cs实体类

public class employee
    {
        public string lastName { get; set; }
        public string firstName { get; set; }
        public string city { get; set; }
        public string state { get; set; }
    }

Program.cs

class Program
    {
        static void Main(string[] args)
        {

            List<employee> employees = new List<employee>()
            {
                new employee() {firstName="John",lastName="Smith",city="哈佛镇",state="PA"},new employee() {firstName="Jane",lastName="Doe",city="尤因",state="NJ"},new employee() {firstName="Jack",lastName="Jones",city="华盛顿堡",};

            //从对象列表创建XML结构
            var XMLEmployees = new XElement("Query",from e in employees
                                                     select new XElement("Employee",new XElement("FirstName",e.firstName),new XElement("LastName",e.lastName),new XElement("City",e.city),new XElement("State",e.state)

            Console.WriteLine(XMLEmployees);
            Console.ReadKey();
        }
    }

运行结果如图:
