    //Load the file stream into a Word document.
    using (WordDocument document = new WordDocument(inputStream, FormatType.Docx))
        //Access paragraph in a Word document.
        WParagraph paragraph = document.Sections[0].Paragraphs[3] as WParagraph;
        //Create bookmarkstart and bookmarkend instance.
        BookmarkStart bookmarkStart = new BookmarkStart(document, "Northwind");
        BookmarkEnd bookmarkEnd = new BookmarkEnd(document, "Northwind");
        //Add bookmarkstart at index zero.
        paragraph.Items.Insert(0, bookmarkStart);
