Question

我昨天在google iTextSharp上找到了pdf填充数据。

但是当我试图阅读pdf时，我没有从pdf获得acrofields。

这是代码

private void ListFieldNames()
    {
        string pdfTemplate = @"E:\Vikas\Projects\PdfWriter\PdfWriter\nbc-app.pdf";


        // create a new PDF reader based on the PDF template document
        PdfReader pdfReader = new PdfReader(pdfTemplate);
        AcroFields formfields = pdfReader.AcroFields;
        // create and populate a string builder with each of the 
        // field names available in the subject PDF

        foreach (KeyValuePair<string, AcroFields.Item> de in formfields.Fields)
        {
            sb.Append(de.Key.ToString() + Environment.NewLine);
        }

        // Write the string builder's content to the form's textbox
        txtbx.TextMode = TextBoxMode.MultiLine;
        txtbx.Width = 500;
        txtbx.Rows = 40;
        txtbx.Text = sb.ToString();

        //txtbx.SelectionStart = 0;
    }

比我正在调试我看到了reader.javascript抛出错误（错误在下面）

   }
}

我应该如何解决这个问题？
