  试试这个：

  using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Text;
  using System.Data;
  using System.Xml;
  using System.Xml.Serialization;
  
  
  namespace ConsoleApplication25
  {
      class Program
      {
  
          static void Main(string[] args)
          {
              List<string> dayNames = new List<string>(){"Mo","Tu","We","Th","Fr","Sa","So"};
              string input = "Mo-Fr 06:00-22:00, Sa 07:00-22:00, So 08:00-22:00";
              string[] days = input.Split(new char[] { ',' });
  
              var dayRange = (from d in days
                              select d.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries))
                             .Select(x => new { days = x[0].Trim(), time = x[1].Trim() })
                             .Select(x => new {  
                                 startDay = x.days.Contains("-") ? x.days.Split(new char[] {'-'})[0] : x.days,
                                 endDay = x.days.Contains("-") ? x.days.Split(new char[] {'-'})[1] : x.days,
                                 startTime = x.time.Contains("-") ? x.time.Split(new char[] {'-'})[0] : x.time,
                                 endTime = x.time.Contains("-") ? x.time.Split(new char[] {'-'})[1] : x.time,
                             }); 
  
              var period = dayRange.Select(x => new {
                  open = new {day = dayNames.IndexOf(x.startDay) + 1, time = x.startTime},
                  close = new {day = dayNames.IndexOf(x.endDay) + 1, time = x.endTime}
              });
  
              string formatedPeriods = string.Join(",",period.Select(x => 
                  "{\n\r\"open\": {\n\r" +
                  "\"day\": " + x.open.day.ToString() + "," +   
                  "\"time\": " + x.open.time.ToString() + "\n\r}," +   
                 "{\n\r\"close\": {\n" +
                  "\"day\": " + x.open.day.ToString() + "," +   
                  "\"time\": " + x.open.time.ToString() + "\n\r}\n\r}"   
                  ).ToArray());
              string output = string.Format("\"periods\": [\n\r{0}\n\r]",formatedPeriods );
  
  
          }
  
      }
  
  }

  要做到这一点，我正在使用这样的东西 . 但我认为它无法满足我的确切输出：

  如果有一个组具有相同的开放收盘日范围，则此代码将位于同一组中且不会有所不同 .

  var keyMap = weekDayMap.GroupBy(c => new {c.OpenFrom, c.OpenTo});
              var openingDay = new OpeningHourMapper();
              var period = new List<Period>();
              foreach (var put in keyMap )
              {
                  openingDay = weekDayMap.FirstOrDefault(c => c.OpenFrom == put.Key.OpenFrom && c.OpenTo == put.Key.OpenTo);
                  period.AddRange(GetPeriodList(openingDay, openingDay));
              }
  
  
  
  namespace Controllers.V1.Response.OpeningHourMapper
  {
      public class OpeningHourMapper
      {
          public int StationNumber { get; set; }
  
          public string Weekday { get; set; }
  
          public int WeekdayNumber { get; set; }
  
          public string OpenFrom { get; set; }
  
          public string OpenTo { get; set; }
      }
  }
