C＃ - 电子邮件作为HTML不工作

我有以下代码：C＃ - 电子邮件作为HTML不工作

MailMessage mail = new MailMessage(); 
SmtpClient SmtpServer = new SmtpClient(Properties.Settings.Default.smtpServer); 
mail.From = new MailAddress(Properties.Settings.Default.mailFrom); 
mail.To.Add(mailto); 
if (!string.IsNullOrEmpty(CC)) { 
mail.CC.Add(CC); 
}; 
mail.Subject = subject; 
mail.IsBodyHtml = true; 
mail.Body = body; 
mail.Priority = MailPriority.High; 
mail.To.Add(mailto); 
SmtpServer.EnableSsl = Properties.Settings.Default.SSL; 
SmtpServer.UseDefaultCredentials = false; 
SmtpServer.Port = Properties.Settings.Default.smtpPort; 
SmtpServer.Credentials = new System.Net.NetworkCredential(Properties.Settings.Default.Username,  Properties.Settings.Default.emailPassword); 
SmtpServer.DeliveryMethod = SmtpDeliveryMethod.Network; 
SmtpServer.Timeout = 200000; 
SmtpServer.Send(mail); 
markEmailAsSent(uid);

我尝试发送以下为HTML，但邮件没有被发送，所以，我收到了原始的HTML回来。我已包括mail.IsBodyHtml = true;所以我不知道为什么这不起作用。

这里是消息的内容：

是什么'body'看起来像在代码 – Laazo

'mailto'缺失报价BTW –

使用'AlternateView'例如http://stackoverflow.com/questions/2555813/what-does-mailmessage-isbodyhtml-do –

更改HTML到：

<html> <head> <title>Trilogy</title> <style type="text/css"> </style> </head> <body> <p align="left" class="style8">bla bla bla bla bla<br /> <br /> <strong>Sometext</strong> <br />t: 01666 666 666 <br />e: <a href="mailto:[email protected]"</a></p> 

</body> </html>

据做到规范，这一点;

<p align="left" class="style8">bla bla bla bla bla<br /> 
<br /> 
<strong>Sometext</strong> 
<br />t: 01666 666 666 
<br />e: <a href="mailto:[email protected]"</a></p>

应该足够
