		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";
			ClientSize = new Size(300, 100);
			bo1 = new TextBox();
			bo1.Location = new Point(50, 20);
			bo1.Size = new Size(100, 20);
			Controls.AddRange(new Control[] {
				bo1
			});
			formSub sub = new formSub();
			sub.fm = this;
			sub.Show();
		}
		[STAThread]
		public static void Main() {
			Application.Run(new formMain());
		}
	}
}

以上。
