Attaching images in the body of a letter in C #

Question

How can I attach an image in a telephoto object. I wrote the code below

System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage(); string UserName = " [e-mail] "; string Password = "my password"; message.To.Add(new System.Net.Mail.MailAddress(" [e-mail] ")); message.From = new System.Net.Mail.MailAddress(" [e-mail] "); message.Subject = "test subject"; message.Body = "<img src=@ 'C:\\Sunset.jpg'/>"; message.IsBodyHtml = true; System.Net.Mail.SmtpClient smtpClient = new System.Net.Mail.SmtpClient(); smtpClient.Host = "hostname"; smtpClient.Port = 25; smtpClient.Credentials = new System.Net.NetworkCredential(UserName, Password); smtpClient.Send(message); 

The code is fine, as I get the message, but the image goes like [X] inside the body, not like the image. How to solve this? The right way?

  string attachmentPath = Environment.CurrentDirectory + @"\test.png"; Attachment inline = new Attachment(attachmentPath); inline.ContentDisposition.Inline = true; inline.ContentDisposition.DispositionType = DispositionTypeNames.Inline; inline.ContentId = contentID; inline.ContentType.MediaType = "image/png"; inline.ContentType.Name = Path.GetFileName(attachmentPath); message.Attachments.Add(inline);

Use the so-called LinkedResource . You can find instructions here. Successfully done it.

If the tutorial does not help, feel free to ask for clarification. :)
