我正在尝试使用FreeSpire将安全的PDF转换为XPS并返回PDF,然后使用iTextSharp将它们组合在一起.下面是我转换各种文件的代码段.

{
Spire.Pdf.PdfDocument doc = new Spire.Pdf.PdfDocument();
doc.LoadFromFile(Loan_list[f], FileFormat.DOC);
doc.SaveToFile((Path.ChangeExtension(Loan_list[f],".pdf")), FileFormat.PDF);
doc.Close();
}

bool PDFCheck = reader.IsOpenedWithFullPermissions;
