这是有效的
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,“Title”);是什么杀死它 不知何故,它似乎正在破坏XPSdoc
商店似乎很好 - 我可以得到注释的数量
即使我创建零注释,它也会失败
但印刷品本身并没有失败 - 我得到了有效的印刷品
上面的尝试捕获没有发现错误
打印后几秒钟从出现错误开始
(我有一个未处理异常的处理程序)
指定的视觉效果不是Visual
的祖先
应用程序崩溃,并且永远不会在DocumentViewer中重新绘制XPS文档
我能够使用ScrollViewer获取FlowDocuments以打印注释 并以相同的方式创建商店,所以我认为代码很好
.NET 4.5
答案 0 :(得分:0)
不知道我的大型节目发生了什么,但我现在无法在较小的节目上重现它
弄明白了 在失败的代码中,我没有使用
FixedDocumentSeqeunce fixedDocumentSeqeunce = XPSdoc.GetFixedDocumentSeqeunce();
在printDialog.PrintDocument中,我使用了与控件绑定的EXACT相同的fixedDocumentSeqence。打印必须更改fixedDocumentSeqeunce,因此它需要一个新的fixedDocumentSeqence。
