编号列表框

我有一个排序的列表框,需要显示每个项目的行号。在这个演示中,我有一个带有名称字符串属性的Person类。列表框显示按姓名排序的人员列表。如何将行号添加到列表框的datatemplate???

<Window x:Class="NumberedListBox.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Height="300" Width="300">
    <ListBox 
        ItemsSource="{Binding Path=PersonsListCollectionView}" 
        HorizontalContentAlignment="Stretch">
        <ListBox.ItemTemplate>
            <DataTemplate>
                <TextBlock Text="{Binding Path=Name}" />
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>
</Window>

namespace NumberedListBox
{
    public partial class Window1 : Window
    {
        public Window1()
        {
            InitializeComponent();

            Persons = new ObservableCollection<Person>();
            Persons.Add(new Person() { Name = "Sally"});
            Persons.Add(new Person() { Name = "Bob" });
            Persons.Add(new Person() { Name = "Joe" });
            Persons.Add(new Person() { Name = "Mary" });

            PersonsListCollectionView = new ListCollectionView(Persons);
            PersonsListCollectionView.SortDescriptions.Add(new SortDescription("Name", ListSortDirection.Ascending));

            DataContext = this;
        }

        public ObservableCollection<Person> Persons { get; private set; }
        public ListCollectionView PersonsListCollectionView { get; private set; }
    }

    public class Person
    {
        public string Name { get; set; }
    }
}
