How to convert doc to pdf using LibreOffice and C#

The string that I'm using to convert the documents is as below. I'm not sure if it's a problem with the parameters passed to soffice.

soffice --convert-to pdf --outdir C:\test\NPP\LOTestOutputs\ C:\test\NPP\MBI_CONVERSION_PRESETS.docx

Also tried:

soffice --convert-to pdf C:\test\NPP\MBI_CONVERSION_PRESETS.docx --outdir C:\test\NPP\LOTestOutputs\

And this is passed to a code in c# which starts a process and executes the arguments passed to it. The problem is that the process waits endlessly at proc.WaitForExit(). I was able to execute a simpler command [soffice --convert-to pdf MBI_CONVERSION_PRESETS.docx] from the cmd prompt

..some more code above related to process init
proc.Start();
proc.BeginOutputReadLine();
proc.BeginErrorReadLine();
proc.WaitForExit();

I referred to a similar problem on Stackoverflow And I checked that my user account has administrator rights. And I am not sure why I cannot convert the document using libreoffice.

The libreoffice version : 5.4

Hoping to get some tips on stackoverflow. Please let me know if you need any info regarding my tests.

EDIT 2: the error read from the stream

{Error: Please verify input parameters... (SfxBaseModel::impl_store <C:\test\NPP\LOTestOutputs" -env:OOO_CWD=2C:\\Users\\dev\\source\\repos\\Converstion\\TestClass\\bin\\Debug/MBI_CONVERSION_PRESETS.pdf> failed: 0x81a)}
Solution

  • The output path was the main culprit here. The directory shouldn't contain the trailing backslash. I posted the same question on a different website and got the answer. The dev team might come up with a fix for the trailing backslash.

    Thanks everyone!
