using System;
using System.IO;
using System.Windows.Forms;
using System.Drawing;

namespace App
{
	public partial class formSub: Form {
		TextBox bo1;
		public formMain fm;
		public formSub() {
			Text = "formSub";
			ClientSize = new Size(300, 200);
			bo1 = new TextBox();
			bo1.Location = new Point(50, 20);
			bo1.Text = "test desu";
			bo1.Size = new Size(100, 20);
			Controls.AddRange(new Control[] {
				bo1
			});
			Button btn1 = new Button();
			btn1.Location = new Point(50, 100);
			btn1.Text = "test";
			btn1.Click += btn1_Click;
			Controls.AddRange(new Control[] {
				btn1
			});
		}
		void btn1_Click(object sender, System.EventArgs e) {
			if (fm != null)
			{
				fm.ReceiveData = bo1.Text;
			}
		}
	}
	public partial class formMain: Form {
		public string ReceiveData {
			set {
				receiveData = value;
				bo1.Text = receiveData;
			}
			get {
				return receiveData;
			}
		}
		TextBox bo1;
		private string receiveData = "";
		public formMain() {
			Text = "formMain";
			BackColor = Color.Azure;
			//ForeColor = Color.Blue;
			ClientSize = new Size(120, 500);
			bo1 = new TextBox();
			bo1.Location = new Point(10, 20);
			bo1.Size = new Size(100, 20);
			Controls.AddRange(new Control[] {
				bo1
			});
			Button btn1 = new Button();
			btn1.Location = new Point(10, 70);
			btn1.Text = "sub";
			btn1.Click += btn1_Click;
			Controls.AddRange(new Control[] {
				btn1
			});
			Button btn2 = new Button();
			btn2.Location = new Point(10, 470);
			btn2.Text = "exit";
			btn2.Click += btn2_Click;
			Controls.AddRange(new Control[] {
				btn2
			});
		}
		void btn1_Click(object sender, System.EventArgs e) {
			formSub sub = new formSub();
			sub.MdiParent = MdiParent;
			sub.fm = this;
			sub.Show();
		}
		void btn2_Click(object sender, System.EventArgs e) {
			Application.Exit();
		}
	}
	public partial class formMdi: Form {
		public formMdi() {
			Text = "formMdi";
			ClientSize = new Size(900, 550);
			IsMdiContainer = true;
			formMain ma = new formMain();
			ma.MdiParent = this;
			ma.Show();
		}
		[STAThread]
		public static void Main() {
			Application.Run(new formMdi());
		}
	}
}

以上。
