推荐答案

IsBodyHTML 标记为true，但您仅提供text / html。您最少需要包含带有文本的备用视图

IsBodyHTML is marked true, but you're only providing text/html. You minimally need to include an alternate view with text

mail2.Body = Hello;

mail2.Body = "Hello";

确保您使用的发件人和收件人不是相同的地址或

make sure you not using Mail from and mailto is same address or

MailMessage mail2 = new MailMessage（mailFrom，mailTo）;

更新

mail2.IsBodyHtml = true; SmtpClient client = new SmtpClient(); client.Port = 25; client.Host = "xxx.xx.xx.xxx"; // smtp host ip mail2.Subject = "Testing."; mail2.Body = "Hello"; string html = "html"; // here is example to user AlternateViews mail2.AlternateViews.Add(AlternateView.CreateAlternateViewFromString(html, new System.Net.Mime.ContentType("text/html")); string Plaintext ="plain text"; mail2.AlternateViews.Add(AlternateView.CreateAlternateViewFromString(Plaintext, new System.Net.Mime.ContentType("text/plain")); mail2.SubjectEncoding = System.Text.Encoding.UTF8; mail2.BodyEncoding = System.Text.Encoding.UTF8; client.Send(mail2);
