这行得通 

FixedDocumentSeqeunce fixedDocumentSeqeunce = XPSdoc.GetFixedDocumentSeqeunce();    
DocumentPaginator paginator = fixedDocumentSeqeunce.DocumentPaginator;

printDialog.PrintDocument(paginator, "Title");

这失败了

AnnotationDocumentPaginator adp = new AnnotationDocumentPaginator(paginator, service.Store); 
// same paginator as above    
printDialog.PrintDocument(adp, "Title");

printDialog.PrintDocument(adp, "标题"); 是什么在杀死它
不知何故，它似​​乎正在破坏 XPSdoc

商店看起来不错-我可以得到注释的计数
即使我创建零个注释它也会失败
但是打印本身不会失败-我得到一个有效的打印
上面的尝试捕获不会捕获错误
几秒钟后打印错误开始于
（我有一个未处理异常的处理程序）

指定的视觉对象不是视觉对象的祖先

应用程序崩溃，并且 XPS 文档永远不会在 DocumentViewer 中重新绘制

我可以使用 ScrollViewer 获取 FlowDocuments 以打印注释
并以相同的方式创建存储，所以我认为代码很好

不知道我的大型程序中发生了什么，但我现在无法在较小的程序上重现它

弄清楚
在我没有使用的失败代码中

FixedDocumentSeqeunce fixedDocumentSeqeunce = XPSdoc.GetFixedDocumentSeqeunce();

在 printDialog.PrintDocument 中，我使用了与控件绑定到的完全相同的 fixedDocumentSeqeunce。Print 必须改变 fixedDocumentSeqeunce，因此它需要一个新的 fixedDocumentSeqeunce。
