I have a DatePicker class in my program, but how do I get an actual value, such as 19.12.2017, from it? I've tried to apply the way that is used to get the value from DateTimePicker in WinForms but it didn't work.

推荐答案

您从 DatePicker 的 SelectedDate 属性中获取选定的值.

You get the selected value from the SelectedDate property of the DatePicker.

<DatePicker x:Name="dp" />

<小时>

DateTime? selectedDate = dp.SelectedDate;
if(selectedDate.HasValue)
{
    string formatted = selectedDate.Value.ToString("dd.MM.yyyy", System.Globalization.CultureInfo.InvariantCulture);
}
