 项目描述

界面内3个文本块，分别记录当前事项、代办事项、已完成事项，使用XML来存储数据

定义XML

<Texts>
	<Text task="task1" date="1"/>
	<Text task="task2" date="2"/>
	<Text task="task2" date="3"/>
</Texts>

定义数据类

namespace WorkList
{
    class Text
    {
        private string task;
        private int date; //1=当前；2=待做；3=已完成

        public string Task { set; get; }
        public int Date { set; get; }



    }
}

主要实现

using System;
using System.Collections.Generic;
using System.Windows.Forms;
using System.Xml;

namespace WorkList
{
    public partial class Form1 : Form
    {

        public Form1()
        {
            InitializeComponent();
        }
        private void save() //保存数据
        {
            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.Load("Text.xml");
            XmlElement xe = xmlDoc.DocumentElement; // DocumentElement 获取xml文档对象的根XmlElement.

            //把所有数据放入集合
            List<Text> textList = new List<Text>();
            for (int i = 1; i < 4; i++)
            {
                Text txt = new Text();
                if (i == 1)
                {

            //写入保存数据

            reader.Close();

            //把数据写进窗口
            for (int i = 0; i < textList.Count; i++)
