前面打了那麼多小怪，但都還沒打到BOSS，今天他來了!!
今天要來實作一個小遊戲：猜數字遊戲

首先先拉出這樣的介面

1. 0 < ? < 100：lab_title
2. textbox：txt_guess
3. label2：lab_msg
4. 確定：btn_ok
5. 重玩：btn_retry
6. 結束：btn_end

        private void btn_retry_Click(object sender, EventArgs e)
        {

        }

        private void btn_end_Click(object sender, EventArgs e)
        {
            if (MessageBox.Show("請問是否離開遊戲嗎？", "離開", MessageBoxButtons.OKCancel, MessageBoxIcon.Information) == DialogResult.OK)
                Application.Exit();
        }
    }
}

今天就到這邊啦，大家辛苦了
