How to save bmp (image) to file

Question

I want to Video File thumbnail. Get Video path and convert to Image. Then convert to bmp, and save the bmp as an image file. If this is possible, please show me a way.

private void add_Video_Image(string sFullname_Path_of_Video)
    {
        //*create mediaplayer in memory and jump to position 
        MediaPlayer mediaPlayer = new MediaPlayer();

        mediaPlayer.MediaOpened += new EventHandler(mediaplayer_OpenMedia);
        mediaPlayer.ScrubbingEnabled = true;
        mediaPlayer.Open(new Uri(sFullname_Path_of_Video));
        mediaPlayer.Position = TimeSpan.FromSeconds(0);
    }

    private void mediaplayer_OpenMedia(object sender, EventArgs e)
    {
        MediaPlayer mediaPlayer = sender as MediaPlayer;
        DrawingVisual drawingVisual = new DrawingVisual();
        DrawingContext drawingContext = drawingVisual.RenderOpen();
        drawingContext.DrawVideo(mediaPlayer, new Rect(0, 0, 160, 100));
        drawingContext.Close();

        double dpiX = 1 / 200;
        double dpiY = 1 / 200;
        RenderTargetBitmap bmp = new RenderTargetBitmap(160, 100, dpiX, dpiY, PixelFormats.Pbgra32);
        bmp.Render(drawingVisual);

        Image newImage = new Image();
        newImage.Source = bmp;
        newImage.Stretch = Stretch.Uniform;
        newImage.Height = 100;

        //save bmp to image
    }
