using System.Drawing;
using System.Text;

namespace App
{
	public partial class Form1: Form {
		TextBox bo1;
		MenuStrip menuStrip1;
		ToolStripMenuItem openToolStripMenuItem;
		ToolStripMenuItem saveToolStripMenuItem;
		ToolStripMenuItem quitToolStripMenuItem;
		public Form1() {
			Text = "memo";
			ClientSize = new Size(500, 500);
			bo1 = new TextBox();
			bo1.Text = "本日は晴天なり";
			bo1.Multiline = true;
			bo1.Font = new Font("ＭＳ Ｐゴシック", 12);
			bo1.Dock = DockStyle.Fill;
			this.menuStrip1 = new MenuStrip();
			this.menuStrip1.Location = new Point(0, 0);
			this.menuStrip1.Name = "menu";
			this.menuStrip1.Size = new Size(353, 24);
			this.menuStrip1.TabIndex = 1;
			this.menuStrip1.Text = "menu";
			this.openToolStripMenuItem = new ToolStripMenuItem();
			this.openToolStripMenuItem.Name = "open";
			this.openToolStripMenuItem.Text = "open";
			this.openToolStripMenuItem.Click += new System.EventHandler(this.openToolStripMenuItem_Click);
			this.saveToolStripMenuItem = new ToolStripMenuItem();
			this.saveToolStripMenuItem.Name = "save";
			this.saveToolStripMenuItem.Text = "save";
			this.saveToolStripMenuItem.Click += new System.EventHandler(this.saveToolStripMenuItem_Click);
			this.quitToolStripMenuItem = new ToolStripMenuItem();
			this.quitToolStripMenuItem.Name = "quit";
			this.quitToolStripMenuItem.Text = "quit";
			this.quitToolStripMenuItem.Click += new System.EventHandler(this.quitToolStripMenuItem_Click);
			this.menuStrip1.Items.AddRange(new ToolStripItem[] {
				this.openToolStripMenuItem,
				this.saveToolStripMenuItem,
				this.quitToolStripMenuItem
			});
			Controls.AddRange(new Control[] {
				bo1,
				menuStrip1
			});
		}
		private void openToolStripMenuItem_Click(object sender, EventArgs e) {
			OpenFileDialog dialog = new OpenFileDialog();
			dialog.Filter = "テキストファイル(*.txt)|*.txt";
			dialog.Title = "開く";
			if (dialog.ShowDialog() == DialogResult.OK)
				bo1.Text = File.ReadAllText(dialog.FileName, Encoding.GetEncoding("UTF-8"));
		}
		private void saveToolStripMenuItem_Click(object sender, EventArgs e) {
			SaveFileDialog dialog = new SaveFileDialog();
			dialog.Filter = "テキストファイル(*.txt)|*.txt";
			dialog.Title = "保存";
			if (dialog.ShowDialog() == DialogResult.OK)
			{
				File.WriteAllText(dialog.FileName, bo1.Text);
			}
		}
		private void quitToolStripMenuItem_Click(object sender, EventArgs e) {
			DialogResult result = MessageBox.Show("メモ帳を終了します", "終了", MessageBoxButtons.YesNo);
			if (result == DialogResult.Yes)
			{
				Close();
			}
		}
		[STAThread]
		public static void Main(string[] args) {
			Application.Run(new Form1());
		}
	}
}

以上。
