Adding logo image to email message

Donald Symmons 3,066

How do I add my logo at the top of my email message?
I need a simple way to do this. Thank you

Here is my code to send email to user; I want to place the logo before string body ="Hello" + txtname.Text.Trim() +",";

 using (MailMessage mm = new MailMessage("******@mywebsite.com", mailtxtbx.Text))  
        {  
            mm.Subject = "Activate Account";  
            string body = "Hello " + txtname.Text.Trim() + ",";  
            body += "<br /><br />Successful Registration";  
            body += "<br /><br />Please click the button to activate your account";  
            body += "<br /><br /><a style='display: block; width: 200px; height: 30px; background: #32CD32;padding: 15px;font-family: Nunito; text-align:center; border-radius: 5px;color: white;font-weight: 700;text-decoration: none;' href = '"  
            + Request.Url.AbsoluteUri.Replace("signup.aspx", "activation.aspx?ActCode=" + actCode) + "'>Activate your new account</a>";  
            body += "<br /><br />Thanks";  
            mm.Body = body;  
            mm.IsBodyHtml = true;  
  
            SmtpClient SMTP = new SmtpClient("relay-hosting.secureserver.net", 25);  
            SMTP.UseDefaultCredentials = false;  
            SMTP.Credentials = new NetworkCredential()  
            {  
                UserName = "******@mywebsite.com",  
                Password = "xxxxxxxxxx"  
            };  
            SMTP.EnableSsl = false;  
            SMTP.Send(mm);  
        }

Hi @Donald Symmons ,
I suggest you could use LinkedResource. You could do like this:

private AlternateView Mail_Body()    
    {    
        string path = Server.MapPath(@"Images/photo.jpg");    
        LinkedResource Img = new LinkedResource(path, MediaTypeNames.Image.Jpeg);    
        Img.ContentId = "MyImage";    
        string str = @"    
            <table>    
                <tr>    
                    <td>    
                      <img src=cid:MyImage  id='img' alt='' width='100px' height='100px'/>     
                    </td>    
                </tr>  
                <tr>  
                     <td>  
                          'hello'   
                     </td>  
                 </tr>  
            </table>    
            ";    
        AlternateView AV =     
        AlternateView.CreateAlternateViewFromString(str, null, MediaTypeNames.Text.Html);    
        AV.LinkedResources.Add(Img);    
        return AV;    
    }    
  
  
using (MailMessage mm = new MailMessage("******@mywebsite.com", mailtxtbx.Text))  
         {  
             mm.Subject = "Activate Account";  
            mm.AlternateViews.Add(Mail_Body());  
             mm.IsBodyHtml = true;  
      
             SmtpClient SMTP = new SmtpClient("relay-hosting.secureserver.net", 25);  
             SMTP.UseDefaultCredentials = false;  
             SMTP.Credentials = new NetworkCredential()  
             {  
                 UserName = "******@mywebsite.com",  
                 Password = "xxxxxxxxxx"  
             };  
             SMTP.EnableSsl = false;  
             SMTP.Send(mm);  
         }

You can solve this by hosting an image anywhere and link it with an <img> tag.
I recommend to create the whole signature as a HTML and when you are satisfied include it within your code.

See the following Code sample

Focus on imageIdentifier and LinkedResource are the key.

var imageIdentifier = "Miata";  
  
var htmlMessage = AlternateView.CreateAlternateViewFromString(  
 $"<p>This is what I'm purchasing in <b>2019</b> to go along with my 2016 model.</p><img src=cid:{imageIdentifier}><p>Karen</p>",  
 null, "text/html");  
  
var fileName = $"{Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Images1")}\\2017Miata.jpg";  
var miataImage = new LinkedResource(fileName, "image/jpeg") {ContentId = imageIdentifier };  
mail.AlternateViews.Add(plainMessage);  
mail.AlternateViews.Add(htmlMessage);  
htmlMessage.LinkedResources.Add(miataImage);
