2. SmtpMail.Send(MailMessage) 此方法復雜、靈活，適合發送附件，而且可以設置MailMessage對象的各種屬性值。 如果我們用ASP.NET寫一個郵件發送的程序，那么首先應該如何得到SMTP。有兩種方法：第一種方法調用目前知名的郵件服務提供商的SMTP，比如新浪、搜狐、網易的免費電子郵箱的SMTP；第二種方法是自己裝一個SMTP虛擬服務器，這個在安裝IIS時一起裝上去的。
MailAttachment
與郵件附件有關的對象類，主要用來提供屬性和方法來創建一個郵件附件對象。
構造函數
創建一個附件對象
MailAttachment objMailAttachment = new MailAttachment( "d:\test。txt" );//發送郵件的附件
