determining MailMessage size with LinkedResources

Is there a .NET method that will tell me the size of a MailMessage (that could contain several LinkedResources)? And if there's no native method (which I assume is the case), is there an accepted way to determine the size manually?

I am sending emails using SmtpClient.Send() and need to know if a message exceeds a given size.

Thanks.

Hmmm. You might be able to get pretty close by looking at the Length fo the stream in the Linkedresource. .ContentStream.Length ?

That does appear to get me what I need for the actual resources itself. Thanks.

That (obviously) doesn't take into account the text in the body of the email, the header, etc. I tried calculating the length of each of those, but I'm still coming up short from what Outlook is claiming.

It could be that Outlook is attaching some of its own overhead and skewing the numbers...I just don't know.
