没有牛B的设计模式，代码精练精练实用，功能齐全，调用简单。。全全完完为码农考虑

MailSmtp ms = new MailSmtp("smtp.qq.com","1215247044","JJHL52771jhl");              //可选参数             ms.SetCC("610262374@qq.com");//抄送可以多个             ms.SetBC("610262374@qq.com");//暗送可以多个             ms.SetIsHtml(true);//默认:true             ms.SetEncoding(System.Text.Encoding.UTF8);//设置格式 默认utf-8              //调用函数             bool isSuccess = ms.Send("1215247044@qq.com", "test", "610262374@qq.com", "哈哈", "哈哈", Server.MapPath("~/Test.dll")); //附件可以不填 收件人可以是多个 传数组              //输出结果             Response.Write(ms.Result);
