HtmlToRtf fails to convert

[Nibu]

Hi there,

I was trying to convert an html file to an rtf file using the HtmlToRtf
class provided in Microsoft.Exchange.Data.TextConverters
(Microsoft.Exchange.Data.Common.dll). But it fails with an exception given
below.

System.NullReferenceException was unhandled
Message="Object reference not set to an instance of an object."
Source="Microsoft.Exchange.Data.Common"

InnerException:

The code used is as given here..

StreamReader reader2 = new StreamReader("d:\\rtftohtml.html");
Stream s2 = new
MemoryStream(System.Text.Encoding.Default.GetBytes(reader2.ReadToEnd()));
Stream newrtf = new MemoryStream();
htmlToRtf.Convert(s2, newrtf);

A similar code works fine for RtfToHtml convert.

Any help greatly appreciated..

Thanks..
Nibu.

Adding a few more bits..
Object is created as show below with no other parameters being set..

HtmlToRtf htmlToRtf = new HtmlToRtf();

Thanks.
