我 1.阅读PDF文件字段ID，
2.在词典中作为配对，
3.迭代所有字段和设置值。对于第2步和第3步添加代码，
var pdfContents = PDFHelper.GeneratePDF(pdfPath, formFieldMap);
public static byte[] GeneratePDF(string pdfPath, Dictionary<string, string> formFieldMap)
{
var output = new MemoryStream();
var reader = new PdfReader(pdfPath);
var stamper = new PdfStamper(reader, output);
var formFields = stamper.AcroFields;
foreach (var fieldName in formFieldMap.Keys)
{
if (formFieldMap[fieldName] != null)
{
formFields.SetField(fieldName, formFieldMap[fieldName]);
}
}
stamper.FormFlattening = true;
stamper.Writer.CloseStream = false;
stamper.Close();
reader.Close();
return output.ToArray();
}
4.使用以下代码在本地系统中下载
PDFHelper.ReturnPDF(pdfContents, "CMS-1500.pdf");
public static void ReturnPDF(byte[] contents, string attachmentFilename)
{
var response = HttpContext.Current.Response;
if (!string.IsNullOrEmpty(attachmentFilename))
response.AddHeader("Content-Disposition", "attachment; filename=" + attachmentFilename);
response.ContentType = "application/pdf";
response.BinaryWrite(contents);
response.End();
}
5.我可以下载文件，但是如果我尝试打开我会“无法打开”，然后我尝试使用https://www.pdf-online.com/osa/repair.aspx修复PDF文件，我收到如下错误消息，
