"How programmatically create RTF document in C# and .Net for 10 minutes?"


Imagine, that in 10 minutes after reading this text you will be able to provide API for your application to create a custom RTF document, using C# or VB.Net.

How programmatically create RTF document in C# and .Net for 10 minutes?

Document .Net is 100% managed C# assembly (SautinSoft.Document.dll) which gives you API to generate documents in RTF format.

The control is designated for manipulation with existing and creation of new documents in Rich Text Format:

  • Insert formatted text, paragraphs, images, plain and nested tables.
  • Specify page size and orientation (height, width, margin vals).
  • Specify font type/name, style, and size.
  • Add page numbering and page breaks, headers and footers.
  • Add sections and pages, bookmarks, Table of contents.
  • Full Unicode support.

The library is absolutely standalone and does not require Microsoft Office or any others.


At a machine with Intel Core i5-3337U and 4GB of RAM the Document .Net generates a simple RTF document (one page filled by formatted text) without saving it to HDD:

  • 1000 documents by 0.45 sec.
  • 10000 documents by 3.61 sec.

Implementation and code samples

To get the ability to create RTF documents in your application, you have to only add a reference to "SautinSoft.Document.dll".

It's easy to add reference to SautinSoft.Document.dll

1. Let's create a simple RTF document with a single line in C#:

Hello My Friend.docx
            // Let's create a simple RTF document.
            DocumentCore rtf = new DocumentCore();
            rtf.Content.End.Insert("Hello my Friend!", new CharacterFormat() { Size = 14, FontName = "Arial"});

2. Let's add a table (2x3) in RTF using for-loop:

            // Let's create a simple RTF document.
            DocumentCore rtf = new DocumentCore();

            // Add a new section
            Section s = new Section(rtf);

            // Let's create a plain table: 2x3.
            Table t = new Table(rtf);            

            // Add 2 rows.
            for (int r = 0; r < 2; r++)
                TableRow row = new TableRow(rtf);
                // Add 3 columns.
                for (int c = 0; c < 3; c++)
                    TableCell cell = new TableCell(rtf);

                    // Set some cell formatting
                    cell.CellFormat.Borders.SetBorders(MultipleBorderTypes.Outside, BorderStyle.Single, Color.Blue, 1.0);
                    cell.CellFormat.PreferredWidth = new TableWidth(60, TableWidthUnit.Point);


                    cell.Content.Start.Insert(String.Format("[{0}, {1}]", r, c));
            // Add this table to the current section.

3. If you want to add an image in RTF in your .Net app:

            // Let's create a simple RTF document.
            DocumentCore rtf = new DocumentCore();

            // Add a new section
            Section s = new Section(rtf);

            // Add the image as a shape with coordinates.
            Picture pict1 = new Picture(rtf, "image1.jpg");

            FloatingLayout fl = new FloatingLayout(
                new HorizontalPosition(10, LengthUnit.Millimeter, HorizontalPositionAnchor.Page),
                new VerticalPosition(10, LengthUnit.Millimeter, VerticalPositionAnchor.TopMargin),
                new Size(70, 70));
            DrawingElement drawingElement = new DrawingElement(rtf, fl, pict1);
