Convert RTF to HTML in .NET

问题

I've managed to do the reverse using WebBrowser and RichTextBox.

But how would I convert RTF to HTML?

As I see, the question is old but maybe someone search solution for this too. Our component RTF to HTML allows to convert RTF to HTML. You may download a component or try online-demo. Try the trial version first if you have a doubt. :) Trial is free.

Here's the code sample for the converting from RTF to HTML in ASP.NET:

    SautinSoft.RtfToHtml r = new SautinSoft.RtfToHtml();
    r.OutputFormat = SautinSoft.RtfToHtml.eOutputFormat.HTML_401;
    r.ImageStyle.IncludeImageInHtml = false; //To save images inside HTML as binary data specify this property to 'true'

    r.ImageStyle.ImageFolder = Server.MapPath(""); 
    r.ImageStyle.ImageSubFolder = "images";
    r.ImageStyle.ImageFileName = "picture";       

    string rtf = ".....";
    string html = r.ConvertString(rtf);        

    //show HTML
    if (html.Length>0)
    {
        Response.Buffer = true;
        Response.Clear();
        Response.ContentType = "text/html";
        Response.Write(html);
        Response.Flush();
        Response.End();
    }

The only problem is when you work on a budget, additional costs mean lower profit, so I started to develop my own version. The main problem is that at the moment it only supports Bold and Italic, and certain entities (&amp, &copy, &reg, &trade, &euro and &###) and lacks both font and color support, but it is still a work in progress. I am adding font and color, but my headache is that these could come from stylesheets rather than the old fashion html tags.

I am writing this in VB.NET and have posted the startup code on CodeProject

If you want to do it programattically you should parse your rtf (is a simple text based file), convert rtf control words to html tags.

Here you can find the rtf specs http://www.biblioscape.com/rtf15_spec.htm

or use an already existing converter: http://sourceforge.net/projects/rtf2html-lite/
