Question

如何将所选日期转换为网格中的短日期类型？我只想表明日期，而不是时间。

vasketidssystemEntities forbindelse = new vasketidssystemEntities();

    public OwnReservations()
    {
        InitializeComponent();
    }
    private void Grid_Loaded(object sender, RoutedEventArgs e)
    {
            ObjectQuery<reservation> reservationer = forbindelse.reservations;

            var query =
            from res in reservationer
            where res.resident_ID == 17
            orderby res.date
            select new { res.date, res.hourofday, res.resident_ID };

           datagrid1.ItemsSource = query.ToList();

Answer 1

您可以编辑要格式化的列的列格式，如下所示：

datagrid1.Columns[0].DefaultCellStyle.Format = "d";

在设置datagrid1的ItemsSource后执行此操作。

source

Answer 2

您可以执行this SO question中的答案，即：

reservationer.Select(a => new { a.date, a.hourofday, a.resident_ID })
                         .AsEnumerable()
                         .Select(p => new 
                                { date = p.date.ToShortDateString(),
                                  hourofday = p.hourofday,
                                  resident_ID = p.resident_ID
                                });

DateTime在网格中转换为shortdatetime
