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("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
            ms.SetIsSSL(true);//是否ssl加密 默认为false

            //调用函数
            bool isSuccess = ms.Send("1215247044@qq.com", "test", "610262374@qq.com", "哈哈", "哈哈", Server.MapPath("~/Test.dll"));

            //输出结果
            Response.Write(ms.Result);
