C# 邮箱mail 发送类
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
MailSmtpms=newMailSmtp("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
boolisSuccess=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);
