Introduction¶

If you want to specify the font, color or insert pictures in your email, you should use Html email format instead of Plain text email format.

Note

Remarks: All of samples in this section are based on first section: Send email in A simple C# XAML Windows Store App project. To compile and run the following example codes successfully, please click here to learn how to create the test project and add reference of EASendMail to your project.

                SmtpClient oSmtp = new SmtpClient();

                // Set sender email address, please change it to yours
                oMail.From = new MailAddress("test@emailarchitect.net");

                // Add recipient email address, please change it to yours
                oMail.To.Add(new MailAddress("support@emailarchitect.net"));

                // Set email subject
                oMail.Subject = "test HTML email from C# XAML project";

                // Set Html body
                oMail.HtmlBody = "<font size=5>This is</font> <font color=red><b>a test</b></font>";

                // Your SMTP server address
                SmtpServer oServer = new SmtpServer("smtp.emailarchitect.net");

                // User and password for ESMTP authentication
                oServer.User = "test@emailarchitect.net";
                oServer.Password = "testpassword";

                // If your SMTP server requires TLS connection on 25 port, please add this line
                // oServer.ConnectType = SmtpConnectType.ConnectSSLAuto;

                // If your SMTP server requires SSL connection on 465 port, please add this line
                // oServer.Port = 465;
                // oServer.ConnectType = SmtpConnectType.ConnectSSLAuto;

                await oSmtp.SendMailAsync(oServer, oMail);
                Result = "Email was sent successfully!";
            }
            catch (Exception ep)
            {
                Result = String.Format("Failed to send email with the following error: {0}", ep.Message);
            }

            // Display Result by Diaglog box
            Windows.UI.Popups.MessageDialog dlg = new
                Windows.UI.Popups.MessageDialog(Result);

            await dlg.ShowAsync();
        }
    }
}

After you received the email by your email client, the body text is like this:

Import Html to email directly¶

You don’t have to write the HTML source body text in your application manually. You can build a html file with HTML tools and use ImportHtmlBodyAsync method to import the html file directly.

You can also refer to the Samples_Windows8 in EASendMail Installer. Those samples demonstrate how to build a HTML email editor and send HTML email with attachment or embedded images/pictures.

At next section I will introduce how to attach file attachment to email message.
