我正在将datagridview数据源设置为对象列表:
grdCurrentMissions.DataSource = _CurrentMissions.Select(o => new
{
column1 = o.ScheduledTime.ToString(@"hh\:mm\:ss"),
column2 = o.DepartureTime.ToString(@"hh\:mm\:ss")
}).ToList();
日期字符串格式适用于现有日期值,但空值显示为12:00 o' clock,如何防止这种情况?

假设ScheduledTime和DepartureTime是DateTime属性,则在未填写时属性等于DateTime.MinValue。因此您可以检查:
grdCurrentMissions.DataSource = currentMissions.Select(o => new
{
column1 = o.ScheduledTime == DateTime.MinValue ? "-" : o.ScheduledTime.ToString(@"hh\:mm\:ss"),
column1 = o.DepartureTime == DateTime.MinValue ? "-" : o.DepartureTime.ToString(@"hh\:mm\:ss"),
}).ToList();
