WPF ListView 绑定图片为什么非得是匿名对象

Question

            <ListView Name="lv" Background="Transparent">
                <ListView.ItemTemplate>
                    <DataTemplate>
                        <Image Source="{Binding Path=ID}"></Image>
                    </DataTemplate>
                </ListView.ItemTemplate>
            </ListView>
        public class IS
        {
            public string ID;
            public IS(string name)
            {
                ID = name;
            }
        }        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            List<IS> iss = new List<IS>();
            foreach (var item in Directory.GetFiles(@"E:\英雄联盟\Air\assets\images\champions").Where(s => s.Contains("Square_0.png")))
            {
                iss.Add(new IS(item));
            }
            lv.ItemsSource = iss.Select(s => new { ID = s.ID });  最后一行代码
为什么lv.ItemsSource = iss;就不行
非得要lv.ItemsSource = iss.Select(s => new { ID = s.ID });  才有图片wpfbinding
