如何在xamarin表单的列表视图中显示从1到1的行号？

// 创建自定义的列表项模板
var itemTemplate = new DataTemplate(() =>
{
    var label = new Label();
    label.SetBinding(Label.TextProperty, new Binding(".", converter: new RowNumberConverter()));
    
    var viewCell = new ViewCell();
    viewCell.View = label;
    
    return viewCell;
});

// 创建列表视图并设置ItemTemplate
var listView = new ListView();
listView.ItemTemplate = itemTemplate;

// 设置列表视图的数据源
listView.ItemsSource = Enumerable.Range(1, 10);

// 行号转换器，用于将行号转换为字符串
public class RowNumberConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        int rowNumber = (int)value;
        return rowNumber.ToString();
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}
