如何从 ListBox 播放 wav 文件？

Question

下午好。我正在 wpf 上制作一个小程序。有一个列表框，其中加载了文件夹中的 wav 文件。有一个 RadioButton（有几个），当您单击它时，某些音频文件会添加到列表中。但是我不知道如何在点击ListBox中的wav元素时播放选定的音轨

        SoundPlayer player;
        string[] playList;
        private void сmClassic(object sender, RoutedEventArgs e)
        {
            lbList.Items.Clear();
            DirectoryInfo dir = new DirectoryInfo(@"C:\Users95355\Desktop\Студент\C#_FourthProject\FourthProject\bin\Debug\music\classic");
            FileInfo[] files = dir.GetFiles("*.wav"); 
            foreach (FileInfo fi in files)
            {
                lbList.Items.Add(fi.ToString());
            }
 
            string d = playList[lbList.SelectedIndex];
           // player.Open(d); Yes, there is a mistake, but I was looking for an alternative
            player.Play();
 
        private void ListBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            
        }
 
        }

            FileInfo[] files = dir.GetFiles("*.wav"); 
            lbList.ItemsSource = files;

        private void ListBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            player.Stop();
