如何从C＃中的TimePicker（WPF）获取价值？

Question

我从visualstudio的nuget下载了MaterialDesignTheme。 http://materialdesigninxaml.net/

如何从TimePicker获得价值？ 我想将此值存储在字符串缓冲区中。 如何实现MainWindow.xaml.cs？

<Grid Grid.Row="1" Grid.Column="1">
            <materialDesign:TimePicker
              Is24Hours="True"
              x:Name="PresetTimePicker"
              SelectedTimeChanged="PresetTimePicker_SelectedTimeChanged" Height="26" Margin="141,94,369,0" RenderTransformOrigin="-0.025,5.923" />
        </Grid>

Answer 1

TimePicker控件具有一个SelectedTime属性，该属性返回一个DateTime?：

DateTime selectedTime = PresetTimePicker.SelectedTime.Value;
string formatted = selectedTime.ToString("HH:mm:ss");
