- Zuishinさんの手順にそってざっと作ってみました。

- 大体のところはデザイナでできます。書いた部分はForm1.csとToDoItem.csです。

-

-

- ```C#

- // ToDoItem.cs

-

- using System;

-

- namespace Questions245208

- {

- public class ToDoItem

- {

- public bool Completed { get; set; }

- public DateTime Deadline { get; set; }

- public string Task { get; set; }

- }

- }

- ```

-

- ```C#

- // Form1.cs

-

- using System;

- using System.Collections.Generic;

- using System.IO;

- using System.Runtime.Serialization;

- using System.Windows.Forms;

- using System.Xml;

-

- namespace Questions245208

- {

- public partial class Form1 : Form

- {

- public Form1()

- {

- InitializeComponent();

-

- if(File.Exists("todo.xml"))

- {

- using(var fs = new FileStream("todo.xml", FileMode.Open))

- {

- var serializer = new DataContractSerializer(typeof(List<ToDoItem>));

- toDoItemBindingSource.DataSource = serializer.ReadObject(fs);

- }

- }

- }

-

- private void Add_Click(object sender, EventArgs e)

- {

- var item = new ToDoItem

- {

- Task = textBox1.Text,

- Deadline = dateTimePicker1.Value,

- };

- toDoItemBindingSource.Add(item);

- }

-

- private void Delete_Click(object sender, EventArgs e)

- {

- //toDoBindingSource.RemoveCurrent();

-

- foreach(DataGridViewRow row in dataGridView1.SelectedRows)

- {

- if(!row.IsNewRow)

- {

- dataGridView1.Rows.Remove(row);

- }

- }

- }

-

- private void Save_Click(object sender, EventArgs e)

- {

- using(var xw = XmlWriter.Create("todo.xml", new XmlWriterSettings { Indent = true, }))

- {

- var serializer = new DataContractSerializer(typeof(List<ToDoItem>));

- serializer.WriteObject(xw, toDoItemBindingSource.List);

- }

- }

- }

- }

- ```

-

- ```C#

- // Form1.Designer.cs

-

- namespace Questions245208

- {

- partial class Form1

- {

- /// <summary>
