public bool _result = false; 
public CaptureCtrlForm _form = new CaptureCtrlForm(); 
 
public void CopyToExample() 
{ 
   // reference the capture control and its audio formats 
   CaptureCtrl capturectrl = _form.CaptureCtrl; 
 
   try 
   { 
      // set an audio device first. use your audio device's name here 
      if (capturectrl.AudioDevices["USB"] == null) 
         throw new Exception("No USB audio device available"); 
 
      capturectrl.AudioDevices["USB"].Selected = true; 
 
      // reference the audio formats collection 
      AudioFormats audioformats = capturectrl.AudioCaptureFormats; 
 
      // allocate a new array for the copied audio formats 
      AudioFormat[] copiedFormats = new AudioFormat[audioformats.Count]; 
 
      // copy them 
      audioformats.CopyTo(copiedFormats, 0); 
 
      // set the result to what we expect
