C # mailbox Mail Send Class

No cow b design pattern, code refining and practical, full-featured, simple call. All finished for the yards farming considerations

MAILSMTP ms = new MAILSMTP ("smtp.qq.com", "1215247044", "xxxx");     Optional parameter     Ms. SETCC ("610262374@qq.com");//CC can be multiple     Ms. SETBC ("610262374@qq.com");//Dark send can be multiple     Ms. Setishtml (TRUE);//default: True     Ms. Setencoding (System.Text.Encoding.UTF8);//format default Utf-8     Ms. Setisssl (TRUE);//Whether SSL encryption defaults to FALSE     //Call function     bool issuccess = Ms. Send ("1215247044@qq.com", "Test", "610262374@qq.com", "haha", "haha", Server.MapPath ("~/test.dll"));     Output result     Response.Write (Ms. Result);
