Convert Rtf to HTML

There is also a sample on the MSDN Code Samples gallery called Converting between RTF and HTML which allows you to convert between HTML, RTF and XAML.

I would check out this tool on CodeProject RTFConverter. This guy gives a great breakdown of how the program works along with details of the conversion.

Writing Your Own RTF Converter

Mike Stall posted the code for one he wrote in c# here :

UPDATED:

I got home and tried the below code and it does not work. For anyone wondering, the clipboard does not just magically convert stuff like I'd hoped. Rather, it allows an application to sort of "upload" a data object with a variety of paste formats, and then then you paste (which in my metaphor would be the "download") the program being pasted into specifies its preferred format. I personally ended up using this code, which has been recommended previously, and it was enormously easy to use and very effective. After you have imported the code (in VStudio, Project -> Add Existing Files) you then just go html to rtf like this:

return HtmlToRtfConverter.ConvertHtmlToRtf(myRtfString);

or the opposite direction:

return RtfToHtmlConverter.ConvertHtmlToRtf(myHtmlString);

(below is my previous incorrect answer, in case anyone is interested in the chronology of this answer haha)

Most if not all of the above answers provide comprehensive, often Library-based solutions to the problem at hand. I am away from my computer and thus cannot test the idea, but one alternative, cheap and vaguely hack-y method would be the following.

private string HTMLFromRtf(string rtfString)
{
            Clipboard.SetData(DataFormats.Rtf, rtfString);
            return Clipboard.GetData(DataFormats.Html);         
}

Again, not totally sure if this would work, but just messing around with some html on my iPhone I suspect it would. Documentation is here. More in depth explanation/docs RE the getting and setting of data models in the clipboard can be found here.

(Yes I am fully aware I'm here years later, but I assume this question is one which some people still want answered).
