如何在C＃MailMessage中嵌入Media Player以播放附件

I'm using a C# MailMessage to attach a wave file (8K) to an email message. I'd like to provide a player within the body of that email message that will play that wave file if the user chooses to do so. I've tried using the embedded <object> version of WMP, and a cid: reference to the file, but Outlook 2003 rejects the object tag and won't run it. If it helps, I know my users will be on Outlook 2003.I'm using a C# MailMessage to attach a wave fil
