WPF Process.Start(pdf) 不打开 PDF

Question

I have a WPF Application, in which I am triggering a PDF file to open on a button click using

System.Diagnotics.Process.Start(PDFfile.pdf);

The PDFfile.pdf and MyApplication.exe exist in the same folder.

The issue is, PDF file doesn't open. When I checked in Task Manager, the Acrobat Reader XI process appears running. The weird part is, while this particular process is running, any other PDF file on PC also does not open on double-click. I have checked my PDF file association is with Acrobat Reader XI on my system. OS: Windows 10, 64-bit C# 7.0

Can someone help me figure out the issue or give some pointers, please?

I have read this question but wasn't much help.

Answer 1

It should work when applied as follows.

Properties -> right click Open to Resources.resx -> Top Left Add Existing File -> select the file.

byte[] resourceFile = Properties.Resources.PDFfile;
        string destination = Path.Combine(Path.GetTempPath(), "PDFfile.pdf");
        System.IO.File.WriteAllBytes(destination, resourceFile);
        Process.Start(destination);
