iTextSharp for some reason is not writing to MemoryStream

My code 

 using (iTextSharp.text.Document document = new iTextSharp.text.Document(iTextSharp.text.PageSize.A4.Rotate()))
            {
                MemoryStream memoryStream = new MemoryStream();

                PdfWriter.GetInstance(document, memoryStream);
                document.Open();
                List<IElement> objects = HTMLWorker.ParseToList(new StringReader(html), null);
                foreach (IElement element in objects)
                {
                    if (element.Chunks.Select(x => x.Content).Contains("page_break_here")) document.Add(Chunk.NEXTPAGE);
                    else document.Add(element);
                }


                byte[] docArray = memoryStream.ToArray();
}

memoryStream.Length is 16

and when I try this:

PdfWriter.GetInstance(document, new FileStream(fullPdfFileAddress, FileMode.Create));

it creates file just fine, but i need to write it into memoryStream.

Building on my comment: The document will only be fully written to the stream when it is closed. However, PdfWriter closes the associated stream as well by default, giving rise to your ObjectDisposedException. You can prevent this from happening by setting its CloseStream property to false:

using (var memoryStream = new MemoryStream())
{
    using (var document = new iTextSharp.text.Document(iTextSharp.text.PageSize.A4.Rotate()))
    {
        PdfWriter writer = PdfWriter.GetInstance(document, memoryStream);
        writer.CloseStream = false;

        // Write PDF here.
    }

    byte[] docArray = memoryStream.ToArray();
}
