将MigraDoc目录添加到PDFsharp PDF

我正在尝试使用PDFsharp和MigraDoc从许多其他文件创建PDF报告文件 .

Basically the workflow is as follows:

• 用户上传2个或更多文档以进行连接

• 用户选择他们想要包含在TOC中的页面

• 将文档连接在一起并生成目录

现在，我可以轻松地连接文档并在PDFsharp中添加书签/大纲 . 我遇到问题的地方是使用MigraDoc创建引用PDFsharp创建的书签/轮廓作为超链接目标的TOC .

Code to add bookmark/outline in PDFsharp (successfully adds the bookmarks):

// Current document is a PdfDocument and Title is the name of the bookmark
CurrentDocument.Outlines.Add(title, page, true, PdfOutlineStyle.Bold);

MigraDoc code to create the TOC page and render it to the current PDFsharp document:

// Create blank page
            PdfPage page = (!hasTitlePage)
                ? AddPage(null, 0, TOC_BOOKMARK_TITLE) // Add to start
                : AddPage(null, 1, TOC_BOOKMARK_TITLE); // Add after title page

            // Get Graphics obj
            XGraphics gfx = XGraphics.FromPdfPage(page);
            gfx.MUH = PdfFontEncoding.Unicode;

            // Create MigraDoc document + Setup styles
            Document document = new Document();
            DefineStyles(document);

            // Add header
            Section section = document.AddSection();
            Paragraph paragraph = section.AddParagraph("Table of Contents");
            paragraph.Format.Font.Size = 14;
            paragraph.Format.Font.Bold = true;
            paragraph.Format.SpaceAfter = 24;
            paragraph.Format.OutlineLevel = OutlineLevel.Level1;

            // Add links - these are the PdfSharp outlines/bookmarks added previously when concatinating the pages
            foreach (var bookmark in CurrentDocument.Outlines)
            {
                paragraph = section.AddParagraph();
                paragraph.Style = "TOC";
                Hyperlink hyperlink = paragraph.AddHyperlink(bookmark.Title);
                hyperlink.AddText($"{bookmark.Title}\t");
                hyperlink.AddPageRefField(bookmark.Title);
            }

            // Render document
            DocumentRenderer docRenderer = new DocumentRenderer(document);
            docRenderer.PrepareDocument();
            docRenderer.RenderPage(gfx, 1);

            return page;

注意 - MigraDoc代码添加了TOC页面，但它无法识别PDFsharp书签 .

Screenshot of the TOC: TOC页面在开始时添加（尽管最后列出了TOC书签）但我无法链接到PDFsharp书签

我确信问题在于我对MigraDoc和/或PDFsharp的理解 .

一等奖是仅使用PDFsharp添加TOC . 我会感谢你指出正确方向的任何帮助 .
