c# - Embedding picture to outlook email body

I have the following code:

string imageSrc = "C:\Documents and Settings\menonsu\Desktop\screenScrapper\Bitmap1.bmp";
oMsg.HTMLBody = "<HTML><BODY><img src = " cid:Bitmap1.bmp@embed "/><br><font size="2" face="Courier New">" + introText + "</font>" + body + "<font size="2" face="Courier New">" + conclText + "</font>" + " </BODY></HTML>";

Microsoft.Office.Interop.Outlook.Attachment attc = oMsg.Attachments.Add(imageSrc, Microsoft.Office.Interop.Outlook.OlAttachmentType.olEmbeddeditem, null, "");
            attc.PropertyAccessor.SetProperty("http://schemas.microsoft.com/mapi/proptag/0x3712001E", "Bitmap1.bmp@EMBED");

//Send the message.
oMsg.Save();

For some reason the email is just showing an x when i try to run this code...anyone know why?

From what I can tell, you are not setting the content id properly. Try to change the code to the following:

attc.PropertyAccessor.SetProperty("http://schemas.microsoft.com/mapi/proptag/0x370E001F", "image/bmp"); 
attc.PropertyAccessor.SetProperty("http://schemas.microsoft.com/mapi/proptag/0x3712001F", "Bitmap1.bmp@EMBED");

I have done this before a little differently. I embedded images in some emails that I had to send from my web app using an 'alternate view' in the system.net.mail

System.Net.Mail.LinkedResource theContent = new System.Net.Mail.LinkedResource({path to image});
theContent.ContentID = "TheContent";

String altViewString = anEmail.Body.replace("{original imageSource i.e. '../Images/someimage.gif'}","cid:TheContent");

System.Net.Mail.AlternateView altView = System.Net.Mail.AlternateView.CreateAlternateViewFromString(altViewString, Nothing, System.Net.Mime.MediaTypeNames.Text.Html);

altView.LinkedResources.add(theContent);

anEmail.Message.AlternateViews.Add(altView);
