using LeadtoolsMediaFoundationExamples.Fixtures; 
 
 
public bool _result = false; 
public CaptureCtrlForm _form = new CaptureCtrlForm(); 
 
public void CopyToExample() 
{ 
   // reference the capture control  
   CaptureCtrl capturectrl = _form.CaptureCtrl; 
 
   try 
   { 
      // set a video device first, you should use your video device name here 
      if (capturectrl.VideoDevices["Analog"] == null) 
         throw new Exception("No Analog video device available"); 
 
      capturectrl.VideoDevices["Analog"].Selected = true; 
 
      // reference the video capture subtypes collection 
      CaptureSubTypes stypes = capturectrl.VideoCaptureSubTypes; 
 
      // allocate a new array for the copied capture subtypes 
      CaptureSubType[] copiedSubtypes = new CaptureSubType[stypes.Count]; 
 
      // copy them 
      stypes.CopyTo(copiedSubtypes, 0); 
 
      // set the result to what we expect 
      _result = (copiedSubtypes.Length == stypes.Count); 
   }
