Outlook 2007 发送邮件

Hi,

If you make add-in for Outlook 2007 or higher try to add the following code before newMail.Send():

   Attachment attachment = newMail.Attachments.Add(
     @"E:\Pictures\image001.jpg"
    , OlAttachmentType.olEmbeddeditem
    , null
    , "Some image display name"
    );

   string imageCid = "image001.jpg@123";

   attachment.PropertyAccessor.SetProperty(
     "http://schemas.microsoft.com/mapi/proptag/0x3712001E"
    , imageCid
    );

   newMail.HTMLBody = String.Format(
     "<body><img src=\"cid:{0}\"></body>"
    , imageCid
    );

Of course you can insert the tag "img" in the existing html body instead of override it like in my example.
