WPF将具有多个页面的XPS转换为PDF

我有一个WPF应用程序,我在其中创建一个XPS文档(来自Excel),然后我就可以将XPS文档转换为PDF文件:

PdfSharp.Xps.XpsConverter.Convert(sourceXpsFile, destPdfFile, 0);

但是当我的XPS文档包含多个页面时,只有第一页转换为PDF。

好像我的XPS文件错了,我创建了多个单个XPS文件,然后我将它们合并:

public void MergeXpsDocument(string newFile, List<XpsDocument> sourceDocuments)
    {
        Thread th = new Thread(() =>
        {    
            if (File.Exists(newFile))
            {
                File.Delete(newFile);
            }

            XpsDocument xpsDocument = new XpsDocument(newFile, System.IO.FileAccess.ReadWrite);
            XpsDocumentWriter xpsDocumentWriter = XpsDocument.CreateXpsDocumentWriter(xpsDocument);
            FixedDocumentSequence fixedDocumentSequence = new FixedDocumentSequence();

            foreach (XpsDocument doc in sourceDocuments)
            {
                FixedDocumentSequence sourceSequence = doc.GetFixedDocumentSequence();
                foreach (DocumentReference dr in sourceSequence.References)
                {
                    DocumentReference newDocumentReference = new DocumentReference();
                    newDocumentReference.Source = dr.Source;
                    (newDocumentReference as IUriContext).BaseUri = (dr as IUriContext).BaseUri;
                    FixedDocument fd = newDocumentReference.GetDocument(true);
                    newDocumentReference.SetDocument(fd);
                    fixedDocumentSequence.References.Add(newDocumentReference);

                }
                doc.Close();
            }
            xpsDocumentWriter.Write(fixedDocumentSequence);
            xpsDocument.Close();
        });
        th.SetApartmentState(ApartmentState.STA);
        th.Start();
    }

也许我应该用另一种方法来合并我的XPS文件?

使用方法来合并我的XPS文档存在问题,我将其更改为此处的代码: Can multiple xps documents be merged to one in WPF?

现在我可以将所有页面转换为PDF格式。
