排球计分

Posted 2020-09-05

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))
            {

                {
                    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;
        }
