感谢ABCpdf帮助我解决了问题。

必须使用XMP和RDF进行设置。

Copyright.txt包含

来自Code背后：

            // Set metadata
        var theXml = File.ReadAllText(context.Server.MapPath("Copyright.txt"));
        var so = new StreamObject(doc.ObjectSoup);
        so.SetText(theXml);
        so.Compress();

        // add dictionary to document catalog
        var cat = (DictAtom)doc.ObjectSoup.Catalog.Atom;
        cat.Add("Metadata", new RefAtom(so));

ABCPdf SetInfo版权状态和通知？
