XML序列化和反序列化

使用 System.Xml.Serialization 命名空间中的 XmlSerializer 类来进行 XML 格式的序列化和反序列化。

using System.IO;
using System.Xml.Serialization;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {

            {
                new Student{ ID = 1,Name="张三",Age = 18 },
                new Student{ ID = 2,Name="李四",Age = 19 },
                new Student{ ID = 3,Name="王五",Age = 17 }
            };
            Create_Xml(stuList);

            List<Student> list = GetXmlToList();

            Console.ReadKey();
        }

        }
