private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
        {
            // 限制輸入0-9 及A-Z a-z 及Backspace
            if (!(e.KeyChar >= '0' && e.KeyChar <= '9') && !(e.KeyChar >= 'a' && e.KeyChar <= 'z') && !(e.KeyChar >= 'A' && e.KeyChar <= 'Z') && e.KeyChar != '\b')
            {
                e.Handled = true;
            }
        }
        private void textBox1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Enter) //判定按下enter
            {
                button1.Focus(); //把焦點放到按鈕上
                button1_Click(sender, e);//並執行Click事件
            }

            if (e.Modifiers == Keys.Control && e.KeyCode == Keys.A)//判定按下 Ctr +A 
            {
                textBox1.SelectAll();
                //((TextBox)sender).SelectAll(); 
            }
        }
        private void button1_Click(object sender, EventArgs e)
        {
            MessageBox.Show("test");
        }
