我正在使用此脚本循环浏览用户文件并填写 details.pdf 模板的副本并将它们合并为一个文件。
我遇到的问题是 tfTotalPrice 字段在我手动打开文档 javascript 并更改某些内容（例如添加警报）之前不会计算。我认为这可能与需要“/CO”字典键有关，但我不明白为什么。我刚刚在 ISO32000-1 文档中读到了这一点。
static void Main(string[] args)
{
int i = 0;
int partsTotal = args.Count();
//template page
string tempDetails = @"C:\temp\Details.pdf";
//final multi page quote
string finishedQuote = @"C:\temp\Quote.pdf";
DateTime processedDate = DateTime.Now;
string dateProc = processedDate.ToString("MM/dd/yyyy");
Console.WriteLine("Please Enter Your Customer Name and Press Enter");
string customer = Console.ReadLine();
//This will hold the memory streams and be used to merge them all
List<byte[]> pagesToMerge = new List<byte[]>();
Document doc = new Document();
PdfSmartCopy copy = new PdfSmartCopy(doc, new FileStream(finishedQuote, FileMode.Create));
doc.Open();
copy.SetMergeFields();
copy.SetPdfVersion(PdfWriter.PDF_VERSION_1_7);
List<PdfReader> readers = new List<PdfReader>();
for (i = 0; i < partsTotal; i++)
{
string partFile = args[i].ToString();
string partFileName = partFile.Substring(partFile.LastIndexOf(@"\") + 1);
string partFileLocation = partFile.Substring(0, partFile.LastIndexOf(@"\"));
Console.WriteLine("Processing : " + partFileName);
PdfReader reader = new PdfReader(RenameFields(tempDetails, i));
readers.Add(reader);
copy.AddDocument(reader);
}
doc.Close();
foreach (PdfReader reader in readers)
{
reader.Close();
}
//Should we open it up?
bool response = GetYorN();
if (response == true)
{
System.Diagnostics.Process.Start(finishedQuote);
}
}

{
//This method creates a new document in memory with newly named unique fields

PdfStamper stamper = new PdfStamper(reader, baos);
stamper.Writer.SetPdfVersion(PdfWriter.PDF_VERSION_1_7);

//AA = Additional Action Annotation Dictionary
PdfDictionary actionDict = widgetRefDict.GetAsDict(PdfName.AA);
//C = Calculation that lives inside of the AA dictionary
PdfDictionary calcDict = actionDict.GetAsDict(new PdfName("C"));
//Plug in the js calc with the new form field names
calcDict.Put(new PdfName("JS"), new PdfString(newJS));
//stamper.SetPageAction(PdfWriter.PAGE_OPEN, PdfAction.JavaScript(newJS, stamper.Writer), 1);
//close up shop and return the new doc in memory
stamper.Close();
reader.Close();
return baos.ToArray();
}
任何帮助将不胜感激，我一直坚持这一点:(-谢谢
