我想确定当前在ListPicker中选择的项目的名称.我不确定在SelectionChanged事件中要做什么来获取项目的名称.

XAML

<Grid.Resources>
        <DataTemplate x:Name="PickerItemTemplate">
            <TextBlock Text="{Binding Name}"/>
        </DataTemplate>
    </Grid.Resources>

<toolkit:ListPicker x:Name="ThemeListPicker" Header="{Binding Path=LocalizedResources.SettingsPage_ThemeListPicker_Header,Source={StaticResource LocalizedStrings}}"
                                        ItemTemplate="{StaticResource PickerItemTemplate}"
                                        SelectionChanged="ThemeListPicker_SelectionChanged"/>

XAML.CS

protected override void OnNavigatedTo(NavigationEventArgs e)
    {
        base.OnNavigatedTo(e);

        themeList = new List<Theme>();
        themeList.Add(new Theme() { Name = "light" });
        themeList.Add(new Theme() { Name = "dark" });
        ThemeListPicker.ItemsSource = themeList;
    }

private void ThemeListPicker_SelectionChanged(object sender,SelectionChangedEventArgs e)
    {
        //get the name of the current item in the listpicker?
    }

解决方法

var item = (sender as ListPicker).SelectedItem;
