需求：作为一名现场记分员，我希望详细记录比赛现场比分增长情况，以便观众及运动员、教练员及时掌握比赛状况。（满意条件：每一次比分的改变，都要形成一条记录）。
计划：估计此次工作需要长时间的努力。
需求分析: 程序需要能做到每次分数变化的时候都要记录。
设计文档：
1、排球比赛采用五局三胜制。前四局每局25分，每局比赛完成后交换场地，达到24分时，必须比赛的双方相差2分才能分出胜负；决胜局为15分，比赛的双方任何一方先达到8分时，交换场地继续比赛，当双方同时达到14分时候，也是必须相差两分才能决出胜负。
2、每加一分，数据库中的数据+1，分数列表行+1。
3、己方失误时。对方增加一分。
代码如下：（添加队伍，并在另一个页面能够看到参赛人员，以便于加分）
//分数
public class ScoreInfo
{
public ScoreInfo()
{}
string name;
public string Name
{
get { return name; }
set { name = value; }
}
int score;
public int Score
{
get { return score; }
set { score = value; }
}
string reason;
public string Reason
{
get { return reason; }
set { reason = value; }
}
public ScoreInfo(string name, int score, string reason)
{
this.name = name;
this.score =score ;
this.reason = reason;
}
}
//队伍信息
public class TeamInfo
{
public TeamInfo()
{}
string team;
public string Team
{
get { return team; }
set { team = value; }
}
string name;
public string Name
{
get { return name; }
set { name = value; }
}
int number;
public int Number
{
get { return number; }
set { number = value; }
}
public TeamInfo(string team, string name, int number)
{
this.team = team;
this.name =name;
this.number = number;
}
}
//三层
1、dal
public int regist(TeamInfo team)
{
string strcom = "insert into Team(Team,Number,Name) values(@team,@number,@name);";
SqlParameter[] pms = { new SqlParameter("@team",team.Team ), new SqlParameter("@number", team.Number), new SqlParameter("@name", team.Name)};
return SqlHelper.ExecuteNonQuery(strcom, pms);
}
public bool updateScore(ScoreInfo score)
{
string strcom = "update Score set score=@score,reason=@reason where name=@name;";
SqlParameter p = new SqlParameter("@name", score.Name);
SqlParameter p1 = new SqlParameter("@score", score.Score);
SqlParameter p2 = new SqlParameter("@reason", score.Reason);
int i = SqlHelper.ExecuteNonQuery(strcom, p, p1, p2);
return i > 0;
}
public List<ScoreInfo> search(string where)
{
string strcom = "select * from Score " + where;
using (SqlDataReader dr = SqlHelper.ExecuteReader(strcom, null))
{
if (dr.HasRows)
{
List<ScoreInfo> students = new List<ScoreInfo>();
while (dr.Read())
{
ScoreInfo student = new ScoreInfo(dr[0].ToString(),dr[1].GetHashCode(), dr[2].ToString());
students.Add(student);
}
return students;
}
else
{ return null; }
}
}
2、bll
public bool updateStudent(ScoreInfo score)
{
return scoreinfo.updateScore(score);
}
public List<ScoreInfo> search(string where)
{
return scoreinfo.search(where);
}
public bool regist(TeamInfo stu)
{
return scoreinfo.regist(stu) > 0;
}
3、表现层
a、html
<form action="Team.ashx" method="post">
请输入队名:
<input name="txt_team" type="text" value="@team" id="team"/><br />
<br />
号 码：<input name="txt_no" type="text" value="@no" id="no"/> 姓 名：<input name="txt_name" type="text" value="@name" id="name"/><br /><br />
号 码：<input name="txt_no" type="text" value="@no" id="no"/>姓 名：<input name="txt_name" type="text" value="@name" id="name"/><br /><br />

<input name="btn_China" type="submit" value="确定" />
<br />
<span>@msg</span>
</form>
b、ashx
blic bll bll = new bll();
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/html";
TeamInfo team = new TeamInfo();
team.Team = context.Request.Form["txt_team"];
team.Number=context.Request.Form["txt_no"].GetHashCode();
team.Name = context.Request.Form["txt_name"];
bool isOk = bll.regist(team);
if (isOk)
{
string duiwu = context.Request.Form["txt_team"];
string no = context.Request.Form["txt_no"];
string name = context.Request.Form["txt_name"];
HttpCookie cookies = new HttpCookie("Regist");
cookies.Values.Add("Team", duiwu);
cookies.Values.Add("No", no);
cookies.Values.Add("Name", name);
cookies.Expires = System.DateTime.Now.AddYears(1);
HttpContext.Current.Response.Cookies.Add(cookies);
context.Response.Cookies.Add(cookies);
string path = context.Request.MapPath("Team.htm");
string html = System.IO.File.ReadAllText(path);
html = html.Replace("@msg", "另一支队伍");
context.Response.Redirect("Play.aspx");
}
4、关于代码复审
代码复审会在后面的代码编写中进行修改，尽量轻装上阵，减小内存。
