C# iTextSharp阅读器javascript错误RSS

我昨天在谷歌iTextSharp上找到了pdf填充数据

但当我试图阅读pdf时，我并没有从pdf中获取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;
    }

private void ListFieldNames（）
{
字符串pdfTemplate=@“E:\Vikas\Projects\PdfWriter\PdfWriter\nbc app.pdf”；
//基于PDF模板文档创建新的PDF阅读器
PdfReader PdfReader=新PdfReader（pdfTemplate）；
AcroFields formfields=pdfReader.AcroFields；
//使用以下各项创建并填充字符串生成器：
//主题PDF中提供的字段名称
foreach（formfields.Fields中的KeyValuePair de）
{
sb.Append（de.Key.ToString（）+Environment.NewLine）；
}
//将字符串生成器的内容写入表单的文本框
txtbx.TextMode=TextBoxMode.MultiLine；
txtbx.宽度=500；
txtbx.Rows=40；
txtbx.Text=sb.ToString（）；
//txtbx.SelectionStart=0；
}

在调试时，我看到reader.javascript抛出错误（错误如下）
