How can I open a playlist file using c# wmp

Question

When I use Player.playlistCollection.newPlaylist("name") it creates a name.wpl file in the default playlist directory (C:\Users\username\Music\Playlists). How can I open this file when I restart the application and pass it to the Player?

Answer 1

I solved it by creating custom playlist files where every line is a media file url. So when the application starts, it reads the file line by line and adds it to the wmp playlist.

    private WMPLib.IWMPPlaylist openPlaylist(string playlistName)
    {
        WMPLib.IWMPPlaylist tempPlaylist = Player.newPlaylist(playlistName, null);
        using (System.IO.StreamReader sr = new System.IO.StreamReader(System.IO.Directory.GetCurrentDirectory() + "\\playlists\\" + playlistName + ".cpt"))
        {
            while (sr.Peek() >= 0)
            {
                string tempMediaUrl = sr.ReadLine();
                WMPLib.IWMPMedia tempMedia = Player.newMedia(tempMediaUrl);
                tempPlaylist.appendItem(tempMedia);
            }
            return tempPlaylist;
        }
    }
