如何比较两个议程项目

问题描述

大家好，



我想比较两个AgendaEvent。



我有这个：

Hi everybody,

I want to compare two agendaEvent with each other.

I have this:

<pre lang="cs">public bool IsOverlapping(AgendaEventViewModel viewModel, AgendaEventViewModel newItem)
        {
            bool isOverlapping = false;
           // ReservationModel r = new ReservationModel(int.Parse(viewModel.id));
            DateTime? begin = DateTime.Parse(viewModel.start);
            DateTime? end = DateTime.Parse(viewModel.end);

            //DateTime? begin2 = DateTime.Parse(newEvent.start);
            //DateTime? end2 = DateTime.Parse(newEvent.end);
            //DateTime dataToCheck;
            //newItem = new AgendaEventViewModel();
            DateTime? begin2 = DateTime.Parse(newItem.start);
            DateTime? end2 = DateTime.Parse(newItem.end);

           // TODO: Check if Event is Overlapping with other events :) Dynamic RoomRules Check should implemented here

            if (begin == begin2)
            {
                this.ShowMessage(Message.Type.Info, Resources.AgendaEvent.IsOverlapping);
                isOverlapping = true;
            }

            return isOverlapping;
        }

但是现在开始和开始2是相同的



我有一个agendaEventViewModel，但是如果你想添加一个其他议程项目，则不允许将它放在相同范围内的同一日期



And如果我这样做：

But now begin and begin2 are the same

I have one agendaEventViewModel but if you want to add a other agenda item, then it is not allowed to place it on the same date in the same range

And If I do this:

<pre lang="cs">public bool IsOverlapping(List<AgendaEventViewModel> viewModel, AgendaEventViewModel newItem)
        {
            bool isOverlapping = false;
           // ReservationModel r = new ReservationModel(int.Parse(viewModel.id));
            //DateTime? begin = DateTime.Parse(viewModel.start);
            //DateTime? end = DateTime.Parse(viewModel.end);

            //DateTime? begin2 = DateTime.Parse(newEvent.start);
            //DateTime? end2 = DateTime.Parse(newEvent.end);
            //DateTime dataToCheck;
            //newItem = new AgendaEventViewModel();
            DateTime? begin2 = DateTime.Parse(newItem.start);
            DateTime? end2 = DateTime.Parse(newItem.end);

           // TODO: Check if Event is Overlapping with other events :) Dynamic RoomRules Check should implemented here

            if (viewModel.Any(m => DateTime.Parse( m.start) == DateTime.Parse(newItem.start)))
            {
                this.ShowMessage(Message.Type.Info, Resources.AgendaEvent.IsOverlapping);
                isOverlapping = true;
            }

            return isOverlapping;
        }
        #endregion

viewmodel为null



这是我的AgendaEventViewModel：

viewmodel is null

This is my AgendaEventViewModel:

<pre lang="cs">public class AgendaEventViewModel
   {
       public string ReturnUrl { get; set; }

       public string id { get; set; }
       public int? funeralId { get; set; }
       public int? reservationId { get; set; }

       public int? roomId { get; set; }

       [Display(Name = "Title", ResourceType = typeof(Resources.AgendaEvent))]
       public string title { get; set; }

       [Display(Name = "Start", ResourceType = typeof(Resources.AgendaEvent))]
       public string start { get; set; }

       [Display(Name = "End", ResourceType = typeof(Resources.AgendaEvent))]
       public string end { get; set; }

       public string top { get; set; }
       public string left { get; set; }

       public List<RoomItemModel> RoomItems { get; set; }
       public List<CateringItemModel> CateringItems { get; set; }

       [Display(Name = "SeatingCapacity", ResourceType = typeof(Resources.AgendaEvent))]
       public int? SeatingCapacity { get; set; } //Max Room SeatingCapacity

       [Display(Name = "ExpectedSeatingCapacity", ResourceType = typeof(Resources.AgendaEvent))]
       public int? ExpectedSeatingCapacity { get; set; } // User Chosen
   }

每次begin2覆盖开始时问题都是dat。所以我甚至无法提出一个议程项目

The problem is dat every time begin2 overwrites begin. So I cant even put one agenda item

推荐答案

return  (begin  <= end2)  && (begin2  <= end);
