// Declare variables.
WMSServer          Server;
IWMSActiveMedia    ActiveMedia;
IWMSActiveStreams  ActiveStreams;
IWMSActiveStream   ActiveStream;
IWMSPlayers        Players;
IWMSPlayer         Player;
IWMSPlaylist       Playlist;

try {
    // Create a new WMSServer object.
    Server = new WMSServerClass();

    // Retrieve an IWMSPlayers object.
    Players = Server.Players;

    // If players are connected, retrieve the first IWMSPlayer object
    // in the IWMSPlayers collection.
    if (Server.Players.Count > 0)
    {
        Player = Server.Players[0];

        // Retrieve the IWMSPlaylist object for the player.
        // NOTE: A valid playlist file is not always returned.
        // This may be the case, for example, if the user requested
        // a specific content file or if a broadcast publishing point
        // is being used.
        Playlist = Player.RequestedPlaylist;

        if (Playlist != null)
        {
            // Retrieve the IWMSActiveMedia object.
            ActiveMedia = Playlist.CurrentMediaInformation;

            // Retrieve the IWMSActiveStreams object.
            ActiveStreams = ActiveMedia.Streams;

            // Use the Count property as an iteration boundary
            // when accessing individual objects in the collection.
            for (int i = 0; i < ActiveStreams.Count; i++)
            {
                //
