Save modified WordprocessingDocument to new file

Question

I\'m attempting to open a Word document, change some text and then save the changes to a new document. I can get the first bit done using the code below but I can\'t figure

Answer 1

Simply copy the source file to the destination and make changes from there.

File.copy(source,destination);
using (WordprocessingDocument wordDoc = WordprocessingDocument.Open(destination, true))
    {
       \\Make changes to the document and save it.
       WordDoc.MainDocumentPart.Document.Save();
       WordDoc.Close();
    }

Hope this works.
