IWMSActiveStreams Object (C#)

The IWMSActiveStreams object contains a collection of IWMSActiveStream objects that provide information about specific audio and video streams in the active media element. The IWMSActiveMediaIWMSActiveMedia Object (C#) provides information about the active element.

The IWMSActiveStreams object exposes the following properties.

In C#, there are two ways to access objects in a collection:

• Access individual objects directly by using a string (where applicable)

• Iterate through the objects by using an index

You must use array notation when retrieving objects from a collection, except when using the get_Item method.

Example

The following example illustrates how to retrieve an IWMSActiveStreams object.

using Microsoft.WindowsMediaServices.Interop;
using System.Runtime.InteropServices;

// Declare variables.
WMSServer          Server;
IWMSActiveMedia    ActiveMedia;
IWMSActiveStreams  ActiveStreams;
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;
        }
    }
}
catch (COMException comExc) {
    // TODO: Handle COM exceptions.
}
catch (Exception e) {
    // TODO: Handle exceptions.
}
