.net - c#: fermeture VideoFileWriter lorsque le flux d'entrée est arrêté - Stack Overflow

I'm working on a c# application that open a communication socket on a predefined ipaddress and port, and receives frame from a another streaming application. When a frame is received it is added to VideoFileWriter object. When 1800 frames are received the writer is closed, so the file is writed on the disc. The code is:

private void StartColor_Click(object sender, RoutedEventArgs e)
        {
            int portaIP = int.Parse(Porta.Text);


            if (!colorClient.IsConnected)
                colorClient.Connect(ServerIp.Text, portaIP);
            else
                colorClient.Disconnect();

            writer = new VideoFileWriter();
            writer.Open("testVideoFileWriter.wmv", 320, 240, 15, VideoCodec.WMV2);      
            count = 1;
        }

        void client_ColorFrameReady(object sender, ColorFrameReadyEventArgs e)
        {
            this.Color.Source = e.ColorFrame.BitmapImage;
            if (writer != null & count < 1800) // acquire a limitated number of frame
            {
                count++;
                if(count%2==0)
                    writer.WriteVideoFrame(ResizeBitmap(BitmapImage2Bitmap(e.ColorFrame.BitmapImage), 320, 240));
            }
            else
            {
                writer.Close();
            }
        }

This code works good, but now I don't want to close the writer after 1800 frames are acquired: I want close the writer only if the input streaming is stopped. How can I perform this task?
