如何显示开放时间?

我试图显示工作时间/天的间隔,它应该是这样的:

Opening Times

我有桌子,我每天都会存储日期编号,开放时间和关闭时间

table
(来源:clip2net.com

然后我创建了query =>

var groups = from s in this.OpenTimes
orderby s.Day
group s by new { s.Till, s.Start } into gr
select new
{
    Time = gr.Key.Start + "-" + gr.Key.Till,
    Days = this.OpenTimes
        .Where(o => o.Start == gr.Key.Start && o.Till == gr.Key.Till)
        .OrderBy(d => d.Day).Select(d => d.Day).ToArray()
};

此查询提供包含在此时间范围内的所有分组时间间隔和天数 但是我遇到了问题 - 我创建了代表这些团体的下半部分,但它没有正常工作。 也许有人可以向我解释所需的视点或显示开放时间的基本逻辑。

感谢您的建议......

下一步方法对我有用:

result screen

  public string OpeningTimesString
      {
         get
         {
            if (!this.OpeningTimes.IsLoaded)
               this.OpeningTimes.Load();
            var groups = (from s in this.OpeningTimes
                       orderby s.Day, s.Start, s.Stop
                       group s by new { Stop = formatTime(s.Stop), Start = formatTime(s.Start), s.Day } into gr
                       select new
                       {
                          Time = gr.Key.Start + "-" + gr.Key.Stop,
                          Day = gr.Key.Day
                       }).ToList();
            string result = "";
            int tmp = 1;
            for (int i = 0; i < groups.Count(); i++)
            {


               //One one = new One();
               bool exit = false;
               tmp = i;
               while (exit == false)
               {
                  if (i + 1 < groups.Count && groups[i].Time.Equals(groups[i + 1].Time))
                  {
                     i++;
                  }
                  else
                  {
                     if (tmp != i)
                        result += (NormalDayOfWeek)(groups[tmp].Day - 1) + "-" + (NormalDayOfWeek)(groups[i].Day - 1) + " : " + groups[i].Time + "<br />";
                     else
                        result += (NormalDayOfWeek)(groups[i].Day - 1) + " : " + groups[i].Time + "<br />";
                     exit = true;
                  }
               }
            }

            if (result.IsNotNull())
               return result;
            else
               return "[%Not yet defined]";
         }
      }
