Answer 1

There is a function called "ReplaceText" in DocX that allows you to replace text within the document.

You must first reference you template like this for example...

DocX letter = DocX.Load(%YOUR TEMPLATE NAME%);

Then you can do...

letter.ReplaceText("%REPLACE_THIS%","%WITH_THIS%");

Hope this helps!

Answer 2

So I usually advocate Using DocXTemplateEngine for this purpose. Simpler than using novacode-docx for template replacement.

Fills in standard mail merge fields in a simple way

var templateEngine = new swxben.docxtemplateengine.DocXTemplateEngine();
templateEngine.Process(
    source = "template.docx",
    destination = "dest.docx",
    data = new {
       Name = "SWXBEN"
    }
);
