Question

我正在使用iTextSharp 5.x.我正在尝试合并两个pdf并保留isTagged标志。当我删除copy.SetTagged（）;结果pdf包含两个pdfs，这很棒。添加copy.SetTagged（）时会出现异常

Exception -->System.ObjectDisposedException: Cannot access a closed file.
at System.IO.__Error.FileNotOpen()
at System.IO.FileStream.get_Position()

这是代码

                List<string> filesToMerge = new List<string> { "C:/dev/dcs/wp-cla-dcs/Hex/Docs/metadata/coverPage.pdf", "C:/dev/dcs/wp-cla-dcs/Hex/Docs/metadata/49W7a.pdf" };
            string outputFileName = "C:/dev/dcs/wp-cla-dcs/Hex/Docs/metadata/results.pdf";

            using (FileStream outFS = new FileStream(outputFileName, FileMode.Create))
            using (Document document = new Document())
            //  using (PdfCopy copy = new PdfCopy(document, outFS))
            using (PdfCopy copy = new PdfSmartCopy(document, outFS))
            {
                {
                    copy.SetTagged();
                    // Set up the iTextSharp document
                    document.Open();
                    foreach (string pdfFile in filesToMerge)
                    {
                        using (var reader = new PdfReader(pdfFile))
                        {
                            copy.AddDocument(reader);
                            copy.FreeReader(reader);
                        }
                    }

                }
            }

尽管有@ bruno-lowagie的评论，但使用iText5可以达到更好的效果。

Uisng iText7，[Given(@"Create new user of type ""(.*)""")] public void CreateNewUser(UserTypeEnum userType) { // some code like e.g.: MyUser user = new MyUser(userType); //... } enum UserTypeEnum { CommonUser, PlatinumUser, Spectre }留下了几个未加标签的内容（所有内容都在源文档中加了标签）。 iText5中的PdfMerger可以正常工作，只需要手动添加Xmp元数据，标题，lang等即可。

PdfCopy

合并pdf并保留SetTagged
