Hi

First we define a file list in fs string array, here we defined two file
for demostration.

And then we create another thread to play the sound.

       string[] fs = new string[]{@"C:\Program Files\MSN
Messenger\phone.wav",
       @"C:\Program Files\MSN Messenger\outgoing.wav"};
       
       void ThreadProc()
       {
           SoundPlayer sp = new SoundPlayer();
           sp.LoadCompleted += new
AsyncCompletedEventHandler(sp_LoadCompleted);
           foreach (string f in fs)
           {
               sp.SoundLocation = f;
               sp.Load();
           }
       }

       private void button2_Click(object sender, EventArgs e)
       {
           Thread t = new Thread(new ThreadStart(ThreadProc));
           t.Start();
       }

       void sp_LoadCompleted(object sender, AsyncCompletedEventArgs e)
       {
           SoundPlayer p = sender as SoundPlayer;
           if (p != null)
           {
               Debug.WriteLine("Play " + p.SoundLocation);
               p.PlaySync();
           }
       }
