 采用三层架构方式做

 比赛分数结果显示如下：

部分程序代码如下：

<connectionStrings>
<add name="paiqiu" connectionString="server=.; database=paiqiu; integrated security=true;"/>
</connectionStrings>

private static readonly string constr = ConfigurationManager.ConnectionStrings["paiqiu"].ConnectionString;
//4.执行返回多个值，多行
public static SqlDataReader ExecuteReader(string sql, params SqlParameter[] pms)
{
SqlConnection con = new SqlConnection(constr);
using (SqlCommand cmd = new SqlCommand(sql, con))
{
if (pms != null)
{
cmd.Parameters.AddRange(pms);
}
try
{
con.Open();
return cmd.ExecuteReader(System.Data.CommandBehavior.CloseConnection);
}
catch (Exception)
{
con.Close();
con.Dispose();
throw;
}
}
}

//UI层
private void Form1_Load(object sender, EventArgs e)
{
//将查询到的数据加载到控件中，显示在页面中
txtNameA.Text = pq.NameA;
txtNameB.Text = pq.NameB;
txtFenShuA.Text = pq.FenShuA;
txtFenShuB.Text = pq.FenShuB;
txtOneA.Text = pq.OneA;
txtOneB.Text = pq.OneB;
txtTwoA.Text = pq.TwoA;
txtTwoB.Text = pq.TwoB;
txtThreeA.Text = pq.ThreeA;
txtThreeB.Text = pq.ThreeB;
txtFourA.Text = pq.FourA;
txtFourB.Text = pq.FourB;
txtFiveA.Text = pq.FiveA;
txtFiveB.Text = pq.FiveB;
txtJieGuo.Text = pq.JieGuo;
}

//Dal层
