Send smtp mail with an image included : a small but interesting code fragment

Back over at codeproject an interesting article has been posted : how to send mail over smtp including an attached image.

This is the code :

//create the mail message
MailMessage mail = new MailMessage();

//set the addresses
mail.From = new MailAddress("[email protected]");
mail.To.Add("[email protected]");

//set the content
mail.Subject = "Mail From Prashant Lavate";

//first we create the Plain Text part
AlternateView plainView = AlternateView.CreateAlternateViewFromString("This is my text , viewable by those clients that don't support html", null, "text/plain");

//then we create the Html part
//to embed images, we need to use the prefix 'cid' in the img src value
//the cid value will map to the Content-Id of a Linked resource.
//thus <img src='cid:logo'> will map to a LinkedResource with a ContentId of 'companylogo'
AlternateView htmlView = AlternateView.CreateAlternateViewFromString("Here is an embedded image.<img src=cid:companylogo>", null, "text/html");

//create the LinkedResource (embedded image)
LinkedResource logo = new LinkedResource( "c:\\temp\\prashant.gif" );
logo.ContentId = "logo";
//add the LinkedResource to the appropriate view
htmlView.LinkedResources.Add(logo);

//add the views
mail.AlternateViews.Add(plainView);
mail.AlternateViews.Add(htmlView);


//send the message
SmtpClient smtp = new SmtpClient("127.0.0.1"); //specify the mail server address
smtp.Send(mail);Remember to set the Language of your code snippet using the Language dropdown.
