.Net--Xml序列化和反序列化Demo

一、Xml序列化

序列化是将对象转换成易于传输的形式的过程，XML 序列化只将对象的公共字段和属性值序列化为 XML 流。XML 序列化不能转换方法、索引器、私有字段或只读属性（只读集合除外）。

Xml序列化Demo，打开VS2022，创建一个WPF应用程序，创建成功后直接来到MainWindow.xaml.cs

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using System.Xml;
using System.Xml.Serialization;

namespace XmlSer
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    /// 
    [XmlRoot]
    public class TestClass {
        private string classname;
        private string name;
        private int age;
        [XmlAttribute]
        public string ClassName { get => classname; set => classname = value; }
        [XmlElement]
        public string Name { get => name; set => name = value; }
        [XmlElement]
        public int Age { get => age; set => age = value; }

        public override string ToString()
        {
            return base.ToString();
        }
    }
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            TestClass testClass = new TestClass();
            testClass.ClassName = "test";
            testClass.Name = "xmlTest";
            testClass.Age = 18;
            FileStream fileStream = File.OpenWrite(@"C:\\programdata\test1.txt");
            using (TextWriter write = new StreamWriter(fileStream)) {
                XmlSerializer serializers = new XmlSerializer(typeof(TestClass));
                serializers.Serialize(write, testClass);
            }
        }
    }
}

成功创建xml文件
