  Im trying to update the bookmark in a word document using below c# code. But it is not updating it.
  
  var doc = new GcWordDocument();
  
  doc.Load(@“H:\aspose_templates\template.dotx”);
  
  doc.Body.Bookmarks.FirstOrDefault()?.Name.Replace(“name”,“NewName”);
  
  doc.Save(@“H:\aspose_templates\new\template.docx”);

  Hi Mithali,

  Thanks for reaching out to us with your query.
  
  Using Replace() method, Bookmark’s Name will not update. Replace method of String returns a new string in which all occurrence of specified characters are replaced with the another characters. It doesn’t update the String property for which Replace method is invoked.
  
  In order to replace the Bookmark’s Name property you can try below code:

  var nameBookmark =doc.Body.Bookmarks.Where(x => x.Name == "name").FirstOrDefault();
  if(nameBookmark != null )
      nameBookmark.Name = "NewName";

  Please refer the attached sample for the same: WordBookmarkDemo.zip

  Best regards,
