.NET：如何打印文件W / O打开它们 [英] .NET: How to print files w/o opening them

问题描述

我们有一个基本的档案文件，我们给用户打印这些文件的可能性的应用程序。它们可以是.txt，doc和.PDF，的.jpg没有任何幻想。 有没有一种.NET的方式将这些文件发送到打印机，而不进一步处理它们，即打开它们？

We have an application that basically archives files and we give the user the possibility to print these files. They can be .txt, .doc, .pdf, .jpg nothing fancy. Is there a .NET way to send these files to the printer without handling them further, ie opening them?

我已经尝试过创建过程与StartInfo.Verb =打印

I already tried creating a process with the StartInfo.Verb = "print"

Process p = new Process();
p.StartInfo.UseShellExecute = false;
p.StartInfo.CreateNoWindow = true;
p.StartInfo.FileName = fileName;
p.StartInfo.Verb = "print"
p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden

p.Start();

它仍然打开，我不想要的文件。有人可以帮忙吗？

It still opens the file which I don't want. Can someone help?

任何帮助将是AP preciated。 托比

Any help would be appreciated. Tobi

推荐答案

我的理解是，大多数应用程序将打开（哪怕是暂时的），当你打印。试着右击MS Word文档，打打印。你会看到Word中打开，打印，并关闭。

My understanding is that most apps will open (even briefly) when you print. Try right-clicking a MS Word document and hitting print. You'll see Word open, print, and close.

不过，您可能想要将它添加到您的code，以保持过程隐蔽性和关闭时完成：

However, you might want to add this to your code to keep the process hidden and to close when finished:

p.Start();
p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
if (p.HasExited == false)
{
   p.WaitForExit(10000);
}

p.EnableRaisingEvents = true;
p.CloseMainWindow();
p.Close();
