2. SmtpMail.Send(MailMessage) 此方法复杂、灵活，适合发送附件，而且可以设置MailMessage对象的各种属性值。 如果我们用ASP.NET写一个邮件发送的程序，那么首先应该如何得到SMTP。有两种方法：第一种方法调用目前知名的邮件服务提供商的SMTP，比如新浪、搜狐、网易的免费电子邮箱的SMTP；第二种方法是自己装一个SMTP虚拟服务器，这个在安装IIS时一起装上去的。
MailAttachment
与邮件附件有关的对象类，主要用来提供属性和方法来创建一个邮件附件对象。
构造函数
创建一个附件对象
MailAttachment objMailAttachment = new MailAttachment( "d:\test。txt" );//发送邮件的附件
