IsBodyHtml = true
无疑是最重要的部分。
但是,如果您想提供一封同时包含 text/plain 部分和 text/html 部分的电子邮件,也可以使用AlternateView
该类:
MailMessage msg = new MailMessage();
AlternateView plainView = AlternateView
.CreateAlternateViewFromString("Some plaintext", Encoding.UTF8, "text/plain");
// We have something to show in real old mail clients.
msg.AlternateViews.Add(plainView);
string htmlText = "The <b>fancy</b> part.";
AlternateView htmlView =
AlternateView.CreateAlternateViewFromString(htmlText, Encoding.UTF8, "text/html");
msg.AlternateViews.Add(htmlView); // And a html attachment to make sure.
msg.Body = htmlText; // But the basis is the html body
msg.IsBodyHtml = true; // But the basis is the html body
