C# does not natively support converting to pdf so you'll need to use a 3rd party tool.

Solution 1

You can't - or at least not in a reasonable time frame.
DOCX is a Zipped XML based document format, PDF is nothing like it.
You can't just take a "raw" DOCX as a stream of bytes and say "this is a PDF" - you have to process the DOCX file into a document and reinterpret that document as a PDF file.

Use a plug in, or an API - it really isn't a good idea to try and do it yourself, there is just too much involved as neither document format is trivial to understand and process.

Read their documentation.
But ... you do realize that HTML also isn't DOCX?

It is possible, but you will need 3rd party library. In that case your code could look like this:

C#

byte[] fileContents = Docx();
using (FileStream file = new FileStream(wordPath, FileMode.Create))
{
	file.Write(fileContents, 0, fileContents.Length);
	file.Close();
}

// dummy object for constructor, since you will not merge outside data
object myDataObject = new object();

DocumentGenerator dg = new DocumentGenerator(myDataObject); 
MemoryStream outputDocumentStream = new MemoryStream(); 
dg.GenerateDocument(file, outputDocumentStream, Pdf);

See more examples if you think this could be helpful for you.
