排球计分程序

标签：自测   dir   scala   val   scalar   ado   估计   int   manager   

   1）计划。

    估计需要两周。

   2）需求分析

   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。

   3）生成设计文档

   当用户打开程序，可以看到中国队和塞尔维亚队的比赛得分情况，可以看到每个球员的得分情况，还可以看出每个队员在所在队伍的地位。

    4）具体设计

    用户进入后能够清楚的看到每个队员的得失情况。

    5）具体代码

   public static class SqlHelper
    {

        //1.连接字符串
        private static readonly string constr = ConfigurationManager.ConnectionStrings["PQ"].ConnectionString;

        //2.执行增删改的
        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();
                }
            }
        }

        //3.执行返回单个值的
        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();
                }
            }
        }

        //4.执行返回SqlDataReader
        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);
                }
                       con.Open();
                    return cmd.ExecuteReader(System.Data.CommandBehavior.CloseConnection);
              }
        }

        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;
        }

      public void ProcessRequest (HttpContext context) {
        context.Response.ContentType = "text/html";
        //拿出所有的数据             
        string name = context.Request.Form["name"];
        int id= Convert.ToInt32( context.Request.Form["id"]);
        string teamname=context.Request.Form["teamname"];
        string status=context.Request.Form["status"];
        string scoreplayer1=context.Request.Form["scoreplayer1"];
       string scoreplayer2=context.Request.Form["scoreplayer2"];
       string totalscore1=context.Request.Form["totalscore1"];
       string totalscore2=context.Request.Form["totalscore2"];

   //插入到数据
        string sql = "insert into player(name,id,teamname,status,scoreplayer1,scoreplayer2,totalscore1,totalscore2) values    

   (@name,@id,@teamname,@status,@scoreplayer1,@scoreplayer2,@totalscore1,@totalscore2)";
        SqlParameter[] ps = {
                                new SqlParameter("@name",name),
                                new SqlParameter("@id",id),
                                new SqlParameter("@teamname",teamname),
                                new SqlParameter("@status",status),
                                new SqlParameter("@scoreplayer1",scoreplayer1),
                                new SqlParameter("@scoreplayer2",scoreplayer2),
                                new SqlParameter("@totalscore1",totalscore1),
                                new SqlParameter("@totalscore2",totalscore2),
                                                                 
                            };
         int result=SqlHelper.ExecuteNonQuery(sql,ps);
         if (result > 0)
         {
             context.Response.Redirect("ListHandler.ashx");
         }       
        context.Response.Write("<script>alert(‘添加失败‘);</script>");
