  • Flexibility: It is possible to insert both simple HTML and complex elements with CSS styles.
  • Efficiency: HTML insertion is fast and without loss of formatting quality.
  1. Add SautinSoft.Document from Nuget.
  2. Create a new document.
  3. Create a Builder based on the document.
  4. To place any HTML content use the method InsertHtml.
