Save a word file as PDF

[C# Programming]

Hello everyone

I need to save the word file as PDF.
I am using Microsoft.Office.Interop for that
object format = Microsoft.Office.Interop.Word.WdSaveFormat.wdFormatPDF;

But after it gets saved to the destination folder, pdf doesn't get open,
as the pdf file gets corrupted.

Please help me to do this job done.

Thanks & Regards
