How do I get value from DatePicker(WPF) in C#?
提问by droft1312
I have a DatePickerclass 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 DateTimePickerin WinForms but it didn't work.

You get the selected value from the SelectedDate property of the DatePicker.
您可以从 DatePicker 的 SelectedDate 属性获得选定的值。
<DatePicker x:Name="dp" />
DateTime? selectedDate = dp.SelectedDate;
if(selectedDate.HasValue)
{
string formatted = selectedDate.Value.ToString("dd.MM.yyyy", System.Globalization.CultureInfo.InvariantCulture);
}
