Here is a solution. Please make a grid or canvas and put the barcode image and use a label with desired text and put the label on desired location relative to barcode grid. So, trick is you can immediately take screenshot of this grid using following code.Then, you are done.

public void ConvertToBitmapSource(UIElement element)
{
    var target = new RenderTargetBitmap(
        (int)element.RenderSize.Width, (int)element.RenderSize.Height,
        96, 96, PixelFormats.Pbgra32);
    target.Render(element);

    var encoder = new PngBitmapEncoder();
    var outputFrame = BitmapFrame.Create(target);
    encoder.Frames.Add(outputFrame);

    using (var file = File.OpenWrite("TestImage.png"))
    {
        encoder.Save(file);
    }
}
