namespace DsWordWeb.Demos{    // This sample demonstrates how the InsertLocation value affects the result    // when inserting a new paragraph near an existing paragraph (the 'anchor').    //    // In this sample, we first add five anchor paragraphs with different background colors,    // interspersed with 'separator' paragraphs with default formatting.    // We then insert four new paragraphs with default formatting near each of the    // anchor paragraph but using different InsertLocation values (Before,    // at Start, at End, and After). Finally, we add the fifth new paragraph    // using the Add() method.    //    // The different background colors of the anchor paragraphs help visualizing    // what happens when different insert locations are used. In particular note    // how InsertLocation.Start and InsertLocation.End create an additional empty    // paragraph with the same style as the style of the anchor paragraph (note    // the same background color). This happens because these insert locations point    // to just after the start, and to just before the end, respectively, of the anchor    // paragraph, so insertion at these locations also splits the anchor paragraph.    public class InsertParagraphs    {        public GcWordDocument CreateDocx()        {            var doc = new GcWordDocument();            var baseStyle = doc.Styles.Add("Base-style", StyleType.Paragraph);            var codeStyle = doc.Styles[BuiltInStyleId.HtmlCode];
