为什么媒体源无法使用Safefilenames？

Question

我想将文件名（没有完整路径）添加到ListBox。

以下代码运作顺畅，但当我将FileNames更改为SafeFileNames时（隐藏项目位置），它不再有效。

XAML

<MediaElement x:Name="mePlayer" Margin="64,0,90,61"/>
<ListBox x:Name="listbox4" Background="Salmon" BorderBrush="Black" BorderThickness="3"/>

CS

private void load_Click(object sender, RoutedEventArgs e)
{
    Microsoft.Win32.OpenFileDialog ofd = new Microsoft.Win32.OpenFileDialog();
    ofd.DefaultExt = ".mp3";
    ofd.Filter = "All|*.*";
    ofd.Multiselect = true;
    Nullable<bool> result = ofd.ShowDialog();
    if (result == true)
    {
        for (int i = 0; i < ofd.FileNames.Length; i++) 
        {
            listbox4.Items.Add(ofd.FileNames[i].ToString());
            listbox4.SelectedItem = ofd.FileName;
            mePlayer.Source = new Uri(
                listbox4.SelectedItem.ToString(), 
                UriKind.RelativeOrAbsolute);
            mePlayer.LoadedBehavior = MediaState.Play;    
        }                       
    }
}
