How to get RTF from RichTextBox

How do I get the text in RTF of a RichTextBox? I'm trying to get like this, but the property does not exist.

RichTextBox rtb = new RichTextBox();
string s = rtb.Rtf;

To get the actual XAML created by the user inside of the RichTextBox:

   TextRange tr = new TextRange(myRichTextBox.Document.ContentStart,
                                myRichTextBox.Document.ContentEnd);
   MemoryStream ms = new MemoryStream();
   tr.Save(ms, DataFormats.Xaml);
   string xamlText = ASCIIEncoding.Default.GetString(ms.ToArray());

EDIT: I don't have code in front of me to test, but an instance of the TextRange type has a Save (to stream) method that takes a DataFormats parameter, which can be DataFormats.Rtf

There are 2 RichTextBox classes, one from the winforms framework and one from the WPF framework:

System.Windows.Controls.RichTextBox wpfBox;
System.Windows.Forms.RichTextBox winformsBox;

Only the Winforms RichTextBox has an Rtf property, the other has a Document property which contains a FlowDocument.
