Question

我正在尝试输出数据库中的所有信息。从我的代码，它的工作原理。但它实际上输出了一切。我想按日期订购。我怎样才能做到这一点。以下是我的代码：

protected override void OnNavigatedTo(NavigationEventArgs e)
    {
        if (!App.ViewModel.IsDataLoaded)
        {
            App.ViewModel.LoadData();
        }

        using (DatabaseContext c = new DatabaseContext(DatabaseContext.ConnectionString))
        {
            //c.CreateIfNotExists();
            if (!c.DatabaseExists())
            {
                c.CreateDatabase();
            }

            c.LogDebug = true;
            //output todolist data from database

            try
            {
                MLongListSelector.ItemsSource = c.ToDoList.ToList();
            }
            catch (Exception exc)
            {
                Console.WriteLine(exc.Source + ":" + exc.Message);
            }



        }
    }

Answer 1

var result = c.ToDoList.OrderBy(datefilter => datefilter.Date).ToList();

按今天的当前日期和时间排序，

DateTime today = DateTime.Today;
var result1 =  c.ToDoList().Where(test => test.Date.Date == today).OrderByDescending(t=>t.Date).ToList();
