How Can I Embed Images Directly into the Body of My Emails?

Improve Your Emails with Embedded Images

Adding images directly into your email body significantly enhances readability and user engagement. While previous methods may have proven problematic, this solution utilizes the AlternateView class to seamlessly embed images as resources within your HTML email.

Here's the updated code:

MailMessage mailWithImg = GetMailWithImg();
MySMTPClient.Send(mailWithImg); //* Remember to configure your SMTPClient beforehand!

private MailMessage GetMailWithImg() {
    MailMessage mail = new MailMessage();
    mail.IsBodyHtml = true;
    mail.AlternateViews.Add(GetEmbeddedImage("c:/image.png"));
    mail.From = new MailAddress("yourAddress@yourDomain");
    mail.To.Add("recipient@hisDomain");
    mail.Subject = "Your Subject";
    return mail;
}

private AlternateView GetEmbeddedImage(String filePath) {
    LinkedResource res = new LinkedResource(filePath);
    res.ContentId = Guid.NewGuid().ToString();
    string htmlBody = $"<img  src=\"cid:{res.ContentId}\" alt="How Can I Embed Images Directly into the Body of My Emails?" ></img>"; //Using string interpolation for clarity
    AlternateView alternateView = AlternateView.CreateAlternateViewFromString(htmlBody, null, MediaTypeNames.Text.Html);
    alternateView.LinkedResources.Add(res);
    return alternateView;
}

This refined code ensures your images are displayed inline within the email, eliminating the need for separate attachments and providing a smoother reading experience for your recipients. Remember to replace "c:/image.png" and the email addresses with your actual file path and addresses.
