RichTextBox rtb = new RichTextBox();
// This call sets the contents of the RichTextBox to the specified FlowDocument.
rtb.Document = flowDoc;
// This call gets a FlowDocument representing the contents of the RichTextBox.
FlowDocument rtbContents = rtb.Document;
' Create a simple FlowDocument to serve as content.
Dim flowDoc As New FlowDocument(New Paragraph(New Run("Simple FlowDocument")))
