Take Snapshot using webcam and EmguCV in c# in console application

Question

I need a simple, but complete, example of capturing a snapshot from Logitech USB webcam in a console application, but I don't find.

The next instruction not works.

private Capture _capture = null; //Camera

Where is Capture definition? In the Emgu.CV.World not it is.

I use the 3.2.0 version of EmguCV.

Thank you in advance.

Did you read the entire article? It is instantiated here:

 private void SetupCapture(int Camera_Identifier)
    {
        //update the selected device
        CameraDevice = Camera_Identifier;

       //Dispose of Capture if it was created before
        if (_capture != null) _capture.Dispose();
        try
        {
            //Set up capture device
            _capture = new Capture(CameraDevice);
            _capture.ImageGrabbed += ProcessFrame;
        }
        catch (NullReferenceException excpt)
        {
            MessageBox.Show(excpt.Message);
        }
    }

Hope this helps.
