C# 邮箱mail 发送类

　　此类的功能包括发送邮件，邮箱格式是否正确，和在不发送邮件的情况下判断邮箱用户名和密码是否正确，鉴于POP检查邮箱用户名和密码出现错误情况返回结果的延迟，用异步线程解决此问题，见代码

　　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

1 2 3 4 5 6 7 8 9 10 11 12 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);
