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 an video device first, you should use your video device name here 
      if (capturectrl.VideoDevices["USB"] == null) 
         throw new Exception("No USB video device available"); 
 
      capturectrl.VideoDevices["USB"].Selected = true; 
 
      // reference the target formats collection 
      TargetFormats formats = capturectrl.TargetFormats; 
 
      // reference the target format object 
      TargetFormat tf = formats[TargetFormatType.MP4]; 
 
      // reference the target video formats object 
      TargetVideoFormats targetformats = tf.VideoFormats; 
 
      // allocate a new array for the copied target video formats 
      int n = targetformats.Count; 
      TargetVideoFormat[] copiedFormats = new TargetVideoFormat[n]; 
 
      // copy them 
      targetformats.CopyTo(copiedFormats, 0); 
 
      // set the result to what we expect 
      _result = (copiedFormats[n - 1].Name == targetformats[n - 1].Name);
