十八周个人作业
- 计划
估计此程序需要3-5天。
- 开发
- 需求分析
用户故事：作为一个赛事管理人员，我希望知道每场比赛队伍得分和积分情况，以便给每队进行排名。
从分析用例故事可以知道完成此程序需要这两项任务：选择业务和查询队伍积分排名。
以下为改程序的活动图：
- 代码规范：使用Vs2010和帕斯卡命名法和骆驼命名法 。
- 具体设计：
根据《2015-2016赛季中国排球联赛竞赛规程》，积分规则如下：
1、计分方式：比赛结果为3:0、3:1时，胜队积3分，负队积0分；比赛结果为3:2时，胜队积2分，负队积1分；积分高者排名在前。
2、当积分相等时，决定名次顺序为：①胜场；②总胜局/总输局（C值）；③总得分/总失分（Z值）。
3、当三队或三队以上Z值仍相等时，则仅在该几队之间依次按照上述第2条决定名次办法①、②、③决定。
故需要建立表头为：队伍名称，胜场，总胜局/总输局，总得分/总失分，积分，名次的数据表。
以下为部分代码：
private void lblIndex_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)//跳转到查询页面
{
this.Close();
historySelect a = new historySelect();
a.Show();
}
private void begin_Click(object sender, EventArgs e)//比赛开始并且检测是否为空
{
if (textName.Text.Trim() == "" || Ateam.Text.Trim() == "" || Bteam.Text.Trim() == "")
{
MessageBox.Show("比赛名、队伍名均不能为空");
}
else
{
writeHistory1 w = new writeHistory1();
w.bisai(textName.Text);
w.TeamA(Ateam.Text);
w.TeamB(Bteam.Text);
w.Show();
this.Close();
}
}
