I am confused on how to retrieve multi selected values from listbox in wpf.

In XAML I have the following listbox with selection mode multiple.

 <ListBox Height="100" HorizontalAlignment="Left" Margin="139,207,0,0" Name="listBox1" VerticalAlignment="Top" Width="120" SelectionChanged="listBox1_SelectionChanged" SelectionMode="Multiple" />    

 <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="319,220,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" />

How do I check in foreach loop now?

        foreach (ListItem li in listBox1.Items)
        {
                ?? // how to check li is selected or not
        }
