什么是正确的循环控制结构以提供正确的输出？

Question

我正在尝试准备一个调度算法，其中我使用了3个DataTables来保存讲师详细信息面板详细信息和大厅可用性详细信息。我使用for循环来访问DataTables。我发现for循环控制结构在这种情况下无法帮助我提供正确的输出

这是我创建表的SQL语句

create table Lecturer_availability(
lecid int,
name varchar(100),
dat1 varchar(100),
time1 varchar(100),
dat2 varchar(100),
time2 varchar(100),
dat3 varchar(100),
time3 varchar(100),
)

create table panel(
groupid int,
e1 int,     //examiner 1
e2 int,     //examiner 2
sup int,    //supervisor   
)

create table Location_availability(
hname varchar(100),
dat1 varchar(100),
time1 varchar(100),
dat2 varchar(100),
time2 varchar(100),
dat3 varchar(100),
time3 varchar(100),
)


create table Schedule(
Location varchar(100),
Group_ID varchar(100),
Date varchar(100),
Time_slot varchar(100),
Examiner_1 varchar(100),
Examiner_2 varchar(100),
Supervisor varchar(100),
)

在c＃代码中我创建3个DataTable并使用for循环我将讲座可用日期和时间与大厅可用日期和时间相匹配，并将已验证的记录插入到日程表中。小组桌上有讲师的讲座

这是我的算法。在这里我只考虑date1和time1

string connString = ConfigurationManager.ConnectionStrings["ConString"].ConnectionString;

 //Load panel details    

            var panel = new DataTable();
            using (var da = new SqlDataAdapter("SELECT * FROM panel",connString))
            {
                da.Fill(panel);

            }

             //Load lecturer avaialability

            var lecavaial = new DataTable();
            using (var da = new SqlDataAdapter("select * from Lecturer_availability", connString))
            {
                da.Fill(lecavaial);

            }

             //Hall Availability

            var hallavaial = new DataTable();
            using (var da = new SqlDataAdapter("select * from Location_availability", connString))
            {
                da.Fill(hallavaial);

            }

 string ex1date1, ex1time1, ex2date1, ex2time1, supdate1, suptime1;
            string ex1name, ex2name, sup, hall, groupid, date, time;

            for (int j = 0; j < hallavaial.Rows.Count; j++)
            {
                for (int k = 0; k < panel.Rows.Count; k++)
                {
                    for (int i = 0; i < lecavaial.Rows.Count; i++)
                    {
                        if (panel.Rows[k]["e1"].ToString() == lecavaial.Rows[i]["lecid"].ToString())
                        {

                                {

                                }
                            }

                            cmd.Connection = connection;
                            cmd.Parameters.AddWithValue("@loc", hall);
                            cmd.Parameters.AddWithValue("@gid", groupid);
                            cmd.Parameters.AddWithValue("@date", date);
                            cmd.Parameters.AddWithValue("@time", time);
                            cmd.Parameters.AddWithValue("@ex1", ex1name);
                            cmd.Parameters.AddWithValue("@ex2", ex2name);

                            cmd.ExecuteNonQuery();
                        }

                    }
                }
            }

这就是我应该如何获得输出
