如何将数据添加到以下类列表中。两个列表都是动态的，并且每个时钟列表项的每日时钟列表可以是不同的。 我现在能够为每个列表，时钟和日常时钟添加数据，但是每日时钟中的数据并没有通过时钟[1] .dailyclockings [1]。我只能在时钟[1] .name和dailyclockings [1] .clockingdate中看到数据，但如果我显示时钟[1] .dailyclocking [1] .clockingdate，则该值为null。
我试图实现的目标如下
Clockings[1].Department = "Testing"
Clockings[1].Name = "Fred"
Clockings[1].DailyClockings[1].ClockingDate = "2017/11/01"
Clockings[1].DailyClockings[1].InClockingTime = "08:00"
Clockings[1].DailyClockings[1].OutClockingTime = "14:00"
Clockings[1].DailyClockings[2].ClockingDate = "2017/11/02"
Clockings[1].DailyClockings[2].InClockingTime = "08:00"
Clockings[1].DailyClockings[2].OutClockingTime = "14:00"
Clockings[1].DailyClockings[3].ClockingDate = "2017/11/03"
Clockings[1].DailyClockings[3].InClockingTime = "08:00"
Clockings[1].DailyClockings[3].OutClockingTime = "14:00"
Clockings[1].DailyClockings[4].ClockingDate = "2017/11/06"
Clockings[1].DailyClockings[4].InClockingTime = "08:00"
Clockings[1].DailyClockings[4].OutClockingTime = "14:00"

答案 0 :(得分：0)
您的代码存在很大的误解：
if (reader.HasRows)
{
while (reader.Read())
{
if (tmpemp == int.Parse( reader["mst_sq"].ToString() ) )
{}
else
{
if (noofusers >1)
{
f.Add(d);
}
col = 0;
noofusers = noofusers + 1;
tmpemp = int.Parse(reader["mst_sq"].ToString());
d.UserName = reader["mst_firstname"].ToString() + " " + reader["mst_lastname"].ToString();
d.StartTime = reader["starttime"].ToString();
d.Department = reader["dept_name"].ToString();
}
if (reader["dy"].Equals(System.DBNull.Value))
{}
else
{
d1.ClockingDate = reader["dy"].ToString().Substring(0, 4) + reader["dy"].ToString().Substring(5, 2) + reader["dy"].ToString().Substring(8, 2);
d1.MinInEarly = reader["mnearly"].ToString();
d1.MinInEarly = reader["mnlate"].ToString();
d1.InClockingTime = reader["tmeclocked"].ToString().Substring(11, 5);
d1.OutClockingTime = reader["earlyclocked"].ToString().Substring(11, 5);
d2.Add(d1);
}
col = col + 1;
d.NoofDaysClocked = col;
}
f.Add(new f.DailyClockings( d2));
f.Add(d);
1）请添加日志或异常处理。 于：
if (tmpemp == int.Parse( reader["mst_sq"].ToString() ) )
{}
或者在：
if (reader["dy"].Equals(System.DBNull.Value))
{}
可能存在错误或db Null，因此您的某个列表不会被填充，您甚至不会知道它，这将导致空值。
2）不要初始化列表中的对象：
f.Add(new f.DailyClockings( d2));
在实例化新对象的过程中，您可能会丢失数据。
像这样使用：
f.DailyClockings dailyClockingsList = new List<DailyClockings>
dailyClockingsList.Add(d2);
f.Add(d);
答案 1 :(得分：0)
对不起，如果我错了，我会发表评论，但我的声誉限制了我。
无论如何，在这部分：
f.Add(new f.DailyClockings( d2));
f.Add(d);
看起来好像你拿Clockings list，将DailyClocking list作为对象添加到列表中，然后将Clockings对象添加到列表中。
它应该是这样的吗？ ：
d.DailyClockings = d2;
f.Add(d);

最后，我借助上述一些答案找到了解决问题的方法。下面是解决方案用于确定它是否是最好的方法，但它确实有效，并给我我需要的结果。
在我的控制器中编写了下面的视图，并对site.css文件进行了更改，以允许对表格进行格式化。从用户选择要传递给存储过程的参数的视图中调用以下内容。
