Как правильно отсортировать ObservableCollection по дате?

Question

Как отсортировать коллекцию по StartDate и EndDate? В моем DashboardView у меня есть 2 ListBox и 2 DatePickers. Оба списка связаны с моей ViewModel. Дата в ObservableCollection я получаю из базы данных Mysql. Я хочу добиться сортировки и отражения сортировки в представлении по датам из средств выбора, одно для StartDate, другое для EndDate. Следует ли использовать временные списки и привязывать к ним уже отсортированные значения? Ниже мой вид ViewModel. Оба типа ObservableCollection имеют свойство DateTime.

 public class DashboardViewModel
    { 
        public ObservableCollection<AvizModel> lstAvizuri { get; set; } = new ObservableCollection<AvizModel>();
        public ObservableCollection<NIRModel> lstNIRuri { get; set; } = new ObservableCollection<NIRModel>();
        public DateTime StartDate { get; set; } = DateTime.Now;
        public DateTime EndDate { get; set; } = DateTime.Now;
        public DashboardViewModel()
        {
            lstAvizuri = BaseConnection.GetAvizList();
            lstNIRuri = BaseConnection.GetNirList();
        }
     
    }

Answer 1

Внес правки не в тот код, на мой взгляд. И сделал реализацию фильтрации во View. Использовал Window для удобства, но сути это не меняет.

BaseConnection

using System;
using System.Collections.Generic;

namespace DataFilteredCollection
{
    public class BaseConnection
    {
        public static IEnumerable<AvizModel> GetAvizList()
        {
            var result = new List<AvizModel>()
            // Example Data
            {
                new AvizModel() {Id=111, TimeStamp = new DateTime(2010, 10, 25)},
                new AvizModel() {Id=222, TimeStamp = new DateTime(2014, 10, 25)},
                new AvizModel() {Id=333, TimeStamp = new DateTime(2017, 10, 25)},
                new AvizModel() {Id=444, TimeStamp = new DateTime(2019, 10, 25)}
            };

            /// Some code

            return result;
        }

        public static IEnumerable<NIRModel> GetNirList()
        {
            var result = new List<NIRModel>()
            // Example Data
            {
                new NIRModel() {Id=123, DataNIR=new DateTime(2010, 10, 25) },
                new NIRModel() {Id=456, DataNIR=new DateTime(2014, 10, 25) },
                new NIRModel() {Id=789, DataNIR=new DateTime(2017, 10, 25) },
                new NIRModel() {Id=402, DataNIR=new DateTime(2019, 10, 25) }
            };


            /// Some code

            return result;
        }
    }
}

DashboardViewModel

using System.Collections.ObjectModel;

namespace DataFilteredCollection
{
    public class DashboardViewModel
    {
        public ObservableCollection<AvizModel> LstAvizuri { get; }
            = new ObservableCollection<AvizModel>();
        public ObservableCollection<NIRModel> LstNIRuri { get; }
            = new ObservableCollection<NIRModel>();
        //public DateTime StartDate { get; set; } = DateTime.Now;
        //public DateTime EndDate { get; set; } = DateTime.Now;

        public DashboardViewModel()
        {
            foreach (var item in BaseConnection.GetAvizList())
                LstAvizuri.Add(item);

            foreach (var item in BaseConnection.GetNirList())
                LstNIRuri.Add(item);
        }
    }
}
