字符串转日期：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

/// <summary>   /// 根据字符串，生成实例   /// </summary>   /// <param name="marks"></param>   public void GenerateModel(DepartmentCategories category, string marks)   {     this.DepartmentCategories = category;     姓名 = marks.Trim().Split(ConstHelper.MAO_HAO).First();     marks = marks.Replace(姓名 + ConstHelper.MAO_HAO, "").Trim();     string regexPattern = $@"\b\d{{4}}/\d{{1,2}}/\d{{1,2}} \d{{1,2}}:\d{{1,2}}:\d{{1,2}}\b";     var regResult = Regex.Match(marks, regexPattern);     string dateString = string.Empty;     if (regResult.Success)     {       dateString = regResult.Groups.Values.First().ToString().Trim();       marks = marks.Replace(dateString, string.Empty);       string format = "yyyy/M/d HH:mm:ss";         DateTime dateTime;         if (DateTime.TryParseExact(dateString, format, CultureInfo.InvariantCulture, DateTimeStyles.None, out dateTime))       {         操作日期 = dateTime;       }       else       {         // 转换失败         Console.WriteLine($"无法将{dateString}日期字符串转换为有效的日期。");       }     }     原因 = marks.Trim();   }

列表转换成字典：

?

1 2 3 4 5 6 7 8 9 10 11

private void AddSpecialCalendarDic(List<SpecialCalendar> specialCalendars)      {          if (specialCalendars.Any())          {              m_SpecialCalendarDic = specialCalendars.GroupBy(m => m.WorkCenterId).Select(m => new { m.Key, List = m.ToList() }).ToDictionary(k => k.Key, v => v.List);          }          else          {              m_SpecialCalendarDic.Clear();          }      }
