Example

using Leadtools; 
using Leadtools.MediaStreaming; 
 
 
public Server _server = null; 
public bool _result = false; 
 
public void IndexContainsExample() 
{ 
   try

      _server = new Leadtools.MediaStreaming.Server(); 
 
      // retrieve a copy of the Live Streams 
      LiveStreams Streams = _server.GetLiveStreams(); 
 
      // create live stream just to demonstrate using audio types IndexOf and Contains 
      LiveStream stream = Streams.CreateLiveStream(); 
 
      //Get the Audio Types  
      AudioTypes AudioTypes = stream.AudioTypes; 
 
      // get the AudioType object of the friendly name "192 kbps, 44.1 KHz, stereo" 
      // this is equal to: 
      // AudioType AudioType = AudioTypes["192 kbps, 44.1 KHz, stereo"]; 
      int nIndex = AudioTypes.IndexOf("192 kbps, 44.1 KHz, stereo");
