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);
