推荐答案

不完全确定你的意思是什么那 - 我有一个创建pdf的过程，然后允许用户预览它们 - 我这样做是通过

not exactly sure what you mean by some of that - I have a process that creates pdfs, then allows the user to preview them - I do this by

System.Diagnostics.Process.Start(@"c:\aPath\somePDF.pdf");

使用用户/客户端机器上的默认应用程序来查看PDF - 他们可以打印/保存/从那里开始 - 它的工作原理无论是使用Acrobat还是Foxit。当程序开始确保他们确实有一个默认的应用程序'可以处理'pdf时，我会检查，但是，这是一个不同的故事



我可以我写了一个预览表格，我认为MigraDoc / PDFsharp包括一个，但我使用iTextSharp并且不想混合PDF堆栈

That uses whatever the default app is on the user/client's machine to view the PDF - they can print/save/whatever from there - it works regardless of whether its Acrobat or Foxit being used. I do run a check when the program starts to make sure that they do have a default application trhat 'can handle' pdf, but, thats a different story

I could have written a preview form, I think MigraDoc/PDFsharp include one, but Im using iTextSharp and didnt want to mix PDF stacks
