Question

How can I export the content of a Flowdocument to OpenXml and vice-versa?

Answer 1

After several hours of research i found that is easier to export to RTF instead of OpenXML or at least no one know how to.

here is how i have done it:

FlowDocument doc = richTextBox1.Document;


TextRange content = new TextRange(richTextBox1.Document.ContentStart, richTextBox1.Document.ContentEnd);
        MemoryStream ms = new MemoryStream();
        textRange.Save(ms, DataFormats.Rtf);

        string val = Encoding.Default.GetString(ms.ToArray());
