邮箱mail 发送类 asp.net C#

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","xxxx");            //可选参数            ms.SetCC("[email protected]");//抄送可以多个            ms.SetBC("[email protected]");//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            ms.SetIsSSL(true);//是否ssl加密 默认为false            //调用函数            bool isSuccess = ms.Send("[email protected]", "test", "[email protected]", "哈哈", "哈哈", Server.MapPath("~/Test.dll"));            //输出结果            Response.Write(ms.Result);
