Having an issue sending an image via email as an embedded image in the body. The image file shows as an attachment which is ok but the inline image portion just shows as a r

Answer 1

We all have our preferred coding styles. This is what I did:

var pictures = new[]
{
    new { id = Guid.NewGuid(), type = "image/jpeg", tag = "justme", path = @"C:\Pictures\JustMe.jpg" },
    new { id = Guid.NewGuid(), type = "image/jpeg", tag = "justme-bw", path = @"C:\Pictures\JustMe-BW.jpg" }
}.ToList();

var content = $@"


{DateTime.Now:ffffdd, MMMM d, yyyy h:mm:ss tt}
Some pictures

    
Color Picture
    


    
Black and White Picture
    


    
Color Picture repeated
    


";

// Update content with picture guid
pictures.ForEach(p => content = content.Replace($"{{{p.tag}}}", $"{p.id}"));
// Create Alternate View
var view = AlternateView.CreateAlternateViewFromString(content, Encoding.UTF8, MediaTypeNames.Text.Html);
// Add the resources
pictures.ForEach(p => view.LinkedResources.Add(new LinkedResource(p.path, p.type) { ContentId = p.id.ToString() }));

using (var client = new SmtpClient()) // Set properties as needed or use config file
using (MailMessage message = new MailMessage()
{
    IsBodyHtml = true,
    BodyEncoding = Encoding.UTF8,
    Subject = "Picture Email",
    SubjectEncoding = Encoding.UTF8,
})
{
    message.AlternateViews.Add(view);
    message.From = new MailAddress("me@me.com");
    message.To.Add(new MailAddress("you@you.com"));
    client.Send(message);
}
