如何在c＃中发送多部分MIME消息？

Question

我想发送带有HTML组件的多部分MIME消息，以及其电子邮件客户端无法处理HTML的人的纯文本组件。 System.Net.Mail.MailMessage类似乎不支持这一点。你怎么做呢？

D'哦，这是非常简单的......但我会离开这里的答案的人谁像我一样，来的那么对于谷歌搜索之前的答案找上... :)

使用AlternateViews，就像这样：

//create the mail message 
var mail = new MailMessage(); 

//set the addresses 
mail.From = new MailAddress("me@mycompany.com"); 
mail.To.Add("you@yourcompany.com"); 

//set the content 
mail.Subject = "This is an email"; 

//first we create the Plain Text part 
var plainView = AlternateView.CreateAlternateViewFromString("This is my plain text content, viewable by those clients that don't support html", null, "text/plain"); 
//then we create the Html part 
var htmlView = AlternateView.CreateAlternateViewFromString("<b>this is bold text, and viewable by those mail clients that support html</b>", null, "text/html"); 
mail.AlternateViews.Add(plainView); 
mail.AlternateViews.Add(htmlView); 

//send the message 
var smtp = new SmtpClient("127.0.0.1"); //specify the mail server address 
smtp.Send(mail);
