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。
代码如下：
public static class SqlHelper
{
private static readonly string constr = ConfigurationManager.ConnectionStrings["player"].ConnectionString;
public static int ExecuteNonQuery(string sql, params SqlParameter[] pms)
{
using (SqlConnection con = new SqlConnection(constr))
{
using (SqlCommand cmd = new SqlCommand(sql, con))
{
if (pms != null)
{
cmd.Parameters.AddRange(pms);
}
con.Open();
return cmd.ExecuteNonQuery();
}
}
}
public static object ExecuteScalar(string sql, params SqlParameter[] pms)
{
using (SqlConnection con = new SqlConnection(constr))
{
using (SqlCommand cmd = new SqlCommand(sql, con))
{
if (pms != null)
{
cmd.Parameters.AddRange(pms);
}
con.Open();
return cmd.ExecuteScalar();
}
}
}
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;
}
}
}
public static DataTable ExecuteDataTable(string sql, params SqlParameter[] pms)
{
DataTable dt = new DataTable();
using (SqlDataAdapter adapter = new SqlDataAdapter(sql, constr))
{
if (pms != null)
{
adapter.SelectCommand.Parameters.AddRange(pms);
}
adapter.Fill(dt);
}
return dt;
}
internal static void ExecuteDataTable()
{
throw new NotImplementedException();
}
}
}
public string bisai(string str)//获取比赛名控件值
{
return name.Text = str;
}
public void TeamA(string str)//获取甲方队伍名
{

}
public void TeamB(string str)//获取乙方队伍名
{

}
public void insert(string win) //记录插入
{
string sql = "insert into paiqiu(game,teamA,teamB,one,two,three,four,five,win,qiangqing) values(@game,@teamA,@teameB,@one,@two,@three,@four,@five,@win,@qiangqing)";

};
SqlHelper.ExecuteNonQuery(sql, sp);
}
