POMultipart HTML and embedded images from .NET without disk access?

copied!<p>I'm working on a product that creates MS Word output by generating an HTML document with the appropriate bits of Word CSS and XML magic embedded in it. I now need to embed RTF (images and styled text) in the document, and so am looking at the multipart HTML generation features in .NET.</p> <p>I'd like to generate the MHTML document by converting the RTF snippets into images in memory, and then just embedding the Base64-encoded data directly into the MHTML object. So far, I can't find any .NET solutions to do that. </p> <p>The <a href="http://msdn.microsoft.com/en-us/library/ms526266(EXCHG.10).aspx" rel="nofollow noreferrer">MS CDO stuff</a> is promising, but it looks like the only way to create an attachment is to provide a URL to the data and use <a href="http://msdn.microsoft.com/en-us/library/ms526569(EXCHG.10).aspx" rel="nofollow noreferrer">AddRelatedBodyPart()</a> to add it to the object.</p> <p>The System.Net.Mail package also looks compelling (as documented <a href="http://www.fuzzydev.com/blogs/dotnet/archive/2006/07/23/System_Net_Mail_AlternateView_LinkedResource.aspx" rel="nofollow noreferrer">here</a> and in a previous question <a href="https://stackoverflow.com/questions/104177/how-do-i-embed-an-image-in-a-net-html-mail-message">here</a>), but I don't see a straightforward way to convert the generated mail object to a string -- the API seems to be focused around sending mail messages, not generating files.</p> <p>Right now, I'm pushing forward with an approach that uses CDO and temporary directories, but I'm unhappy with that as a long-term approach. Any better suggestions?</p>
