Getting Hyperlinks Working in Rich Text Box Using RTF

Question

I am trying to format a hyperlink in a Rich Text Box using the Rich Text Format. I can get basic formatting working thanks to this answer, for example making text bold. However I cannot get the RTF formatted hyperlink to work. I found an example of making an RTF link here. However, when I try to put this in the Rich Text Box as seen below, it causes my application to crash. Any suggestions as to what i'm missing here?

string my_hyperlink_text = @"{\field{\*\fldinst HYPERLINK \"http://www.google.com/\"}{\fldrslt Google}}"
        
if (rtbControl is RichTextBox & rtbControl.Name == "name_of_control")  // Making sure the control is a RichTextBox
       {
            RichTextBox rtb = rtbControl as RichTextBox;
            rtb.Rtf = my_hyperlink_text;
       }

An easy way for getting rtfs to work is to write your text in Microsoft word, copy & paste it to Wordpad and the saving it as a RTF from there. The detour with MS Word is needed, because WordPad does not support entering links in the UI, although it handles them correctly when they come from other sources, like the clipboard. Also, MS Word creates massively bloated rtf.

The rtf file you create this way can then be opened in any text editor and can be used as a string constant in your program.

In your case, I suppose that the prefix and maybe the color table are missing and are causing the problem.

By the way: Wordpad is not much more than a wrapper around the Windows rtf control, i.e. the same control that you are using in your code.
