使用Linq查找列表中具有特定日期的所有项目

Question

I'm trying to list the items that have a specific date and who are assigned to a particular person but for some reason, it doesn't seem to filter the list by date. The aim is to loop through each person within a group and find out what they have been tasked with by the date.

I have tried Contains and any instead but that doesn't really give me the results I'm after. The output of the 'Var i' just seems to be a list of all items across a wide range of dates.

foreach (String consultant in recipent)
            {
                var q = appointmentItems.Where(item => item.Name==consultant);
                ws.Cell(row, col).Value = consultant;
                col++;

                foreach (DateTime date in time)
                {
                    Console.WriteLine(date.ToShortDateString());
                    var i = q.Where(item => item.Date == date.ToShortDateString());
                    loggedTime = 0m;
                    //dailyHours = 7.5m;
                    availableHours = 7.5m;
                    String name = "";
                    String _date = date.ToShortDateString();

                    foreach (CalenderItem item in i)
                    {
                        //populate values and workout availibile hours
                    }
                }
            }

Calender item class

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.Office.Interop.Outlook;

namespace ConsoleApplication1
{
    class CalendarItem
    {
        public String Date { get; set; }

        public decimal Duration { get; set; }

        public string Name { get; set; }

        public string Subject { get; set; }

        public bool AllDayEvent{ get; set; }

        public string Category { get; set; }

        public string BusyStatus { get; set; }

        public string Location { get; set; }
    }
}

The first linq 'Q' works fine in producing a list of items related to 1 person. The second linq 'i' does nothing and returns the same list as 'Q'.

Answer 1

 item.Date == date.ToShortDateString()

That doesn't look good

item.Date seems a date, date.TOShortDateString() is a string.

Different type, different format etc.

Try to do

 item.Date.ToShortDateString() == date.ToShortDateString()
