You can convert any type of Word document to PDF using following code example.

var doc = new Document(MyDir + "input.docx");
doc.Save(MyDir + "output.pdf", SaveFormat.Pdf);

We suggest you please read the following article.

I am already saving them successfully and it is working fine , but in a special case when in a document some pages are portrait and some pages are landscape i am unable to convert the document . as a result either all pages are portrait or landscape , but i want a result in which portrait remain portrait and landscape remain landscape
