xaml - 如何访问我选择的项目？列表框

Question

我的 xaml 页面上有名为 MainListBox 的 ListBox。我可以获得被选中的索引，但是如何从选定的项目中获取数据？

我的 MainListBox_SelectionChanged :

private void MainListBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        int noteID1 = MainListBox.SelectedIndex+1;

        if (MainListBox.SelectedIndex != null)
        {


            //I can get the index that get selected, 
            Debug.WriteLine(MainListBox.SelectedIndex);



        }

         MainListBox.SelectedIndex = -1;

    }

我的 XAML:

<ListBox x:Name="MainListBox" Margin="6,0,0,0" ItemsSource="{Binding Items}" SelectionChanged="MainListBox_SelectionChanged" Height="578" VerticalAlignment="Bottom" Grid.ColumnSpan="3">
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <StackPanel Margin="0,0,0,17" Width="432">
                        <TextBlock x:Name="ItemText" Text="{Binding noteName}" Margin="-2,-13,0,0" Style="{StaticResource PhoneTextExtraLargeStyle}"/>
                        <TextBlock x:Name="DetailsText" Text="{Binding noteText}" Margin="10,-6,0,3" Style="{StaticResource PhoneTextSubtleStyle}"/>
                        <TextBlock x:Name="noteIdText" Text="{Binding noteID}" Margin="10,-6,0,3" Style="{StaticResource PhoneTextSubtleStyle}"/>
                    </StackPanel>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>

请有人指导我，谢谢。 :)

你试过 Main ListBox.Selected Item 吗？
var data = Main ListBox.Selecteditem as [type of class bound to listbox] ;
