问题描述

我的程序中有一个 DatePicker 类，但是如何从中获取实际值，例如19.12.2017？我试图应用在WinForms中从 DateTimePicker 获取值的方法，但是这种方法不起作用。

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

您可以从DatePicker的SelectedDate属性中获取所选值。

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

<DatePicker x:Name="dp" />

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