        public Form1()

        private void button1_Click(object sender, EventArgs e)
        {
            DialogData dd = new DialogData();
            ModalDialog md = new ModalDialog()
            {
                DataDialog = dd  // 赋值
            };
            md.ShowDialog();
            if (md.DialogResult == DialogResult.OK)

                int count = 0;
                foreach (int i in diaocha)
                    count += i;
                this.textBox4.Text = count.ToString();
            }
