Rtf2Html

Convert Rtf via Xaml to Html including images. The code is adapted from Matthew Manelas Codesample with a few tweaks:

1. Usage of RichTextBox is avoided so we do not need to work around STA issues. Instead we use TextEditorCopyPaste.ConvertRtfToXaml via reflection. This is basically the same as using TextRangeBase.Save(..., DataFormats.XamlPackage) with RichTextBox but feels a bit cleaner to me.

2. Added support for processing the zipped XamlPackage stream including images. Requires ZipArchive from System.IO.Compression in .NET 4.5

Simple conversion between Rtf and Xaml is also included by just exposing Microsofts internal implementations.

Examples

Rtf to Html (including image content):

var rtf = File.ReadAllText("doc.rtf");
var htmlResult = RtfToHtmlConverter.RtfToHtml(rtf, "doc");            
htmlResult.WriteToFile("doc.html");

Rtf to Xaml (without content):

var rtf = File.ReadAllText("doc.rtf");
var xaml = RtfToXamlConverter.RtfToXaml(rtf);
File.WriteAllText("doc.xaml", xaml);

Rtf to Xaml package (zip with content)

var rtf = File.ReadAllText("doc.rtf");
using (var xamlStream = RtfToXamlConverter.RtfToXamlPackage(rtf))
    File.WriteAllBytes("doc.xap", xamlStream.ToArray());

Rtf to plain text

var rtf = File.ReadAllText("doc.rtf");
var plainText = RtfToPlaintTextConverter.RtfToPlainText(rtf);
File.WriteAllText("doc.txt", plainText);
