用户故事：

      作为一个观众，我希望了解某一场比赛的比分，以便了解赛况。（满意条件：精确到每一局的结果比分）。

 private void GameLoad()
        {
            cmbA.Items.Clear();

            string sql = "select game from paiqiu";
            SqlDataReader reader = SqlHelper.ExecuteReader(sql);
            if (reader.HasRows)
            {
                while (reader.Read())
                {
                    cmbName.Items.Add(reader[0]);
                }
            }
            reader.Close();
        }
        private void Dgv()
        {
            string sql = "select * from paiqiu";
            dgvGame.DataSource = SqlHelper.ExecuteDataTable(sql);
        }
        private void Form2_Load(object sender, EventArgs e)
        {
            GameLoad();
            dgv();
        }

        private void select_Click(object sender, EventArgs e)//单个查询
        {
            StringBuilder sql = new StringBuilder("select * from paiqiu where 1=1");
            if (!string.IsNullOrEmpty(cmbName.Text))
            {
                sql.Append(" and game=‘" + cmbName.Text + "‘");
            }
            SqlDataReader reader= SqlHelper.ExecuteReader(sql.ToString());
            if (reader.HasRows)
            {
                dgvGame.DataSource = SqlHelper.ExecuteDataTable(sql.ToString());
            }
            else
            {
                MessageBox.Show("没有查询到比赛记录！");
            }
        }

        private void lblWrite_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)//跳转计分页面
        {
            this.Close();
            writeHistory0 a = new writeHistory0();
            a.Show();
        }

        private void linkLabel1_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
        {
             Application.Exit();
        }
