正在从PDF篡改itextsharp返回PDFDocument对象

Question

我想从下面的代码返回文档对象。目前我得到的文档没有页面例外。

private static Document GeneratePdfAcroFields(PdfReader reader, Document docReturn)
    {

         if (File.Exists(System.Configuration.ConfigurationSettings.AppSettings["TEMP_PDF"]))
            File.Delete(System.Configuration.ConfigurationSettings.AppSettings["TEMP_PDF"]);


        PdfStamper stamper = new PdfStamper(reader, new FileStream(System.Configuration.ConfigurationSettings.AppSettings["TEMP_PDF"],FileMode.Create));
        AcroFields form = stamper.AcroFields;

        ///INSERTING TEXT DYNAMICALLY JUST FOR EXAMPLE.
        form.SetField("topmostSubform[0].Page16[0].topmostSubform_0_\\.Page78_0_\\.TextField3_9_[0]", "This value was dynamically added.");
        stamper.FormFlattening = false;

        stamper.Close();

        FileStream fsRead = new FileStream(System.Configuration.ConfigurationSettings.AppSettings["TEMP_PDF"], FileMode.Open);

        Document docret = new Document(reader.GetPageSizeWithRotation(1));

        return docret;
    }

谢谢克里斯。

只是为了重申@BrunoLowagie所说的话，传递文档对象几乎永远不会使
