　　var fromAddress = "[email protected]";

　　string fromPassword = "yj1989120";

　　const string subject = "CV";

　　var smtp = new SmtpClient

　　//如果没有路径，用Stream

　　Attachment letter = new Attachment(FileUploadLetter.FileContent, FileUploadLetter.PostedFile.ContentType);

　　//如果希望通过匿名邮件发送 则

　　var smtp = new SmtpClient

　　{

　　Host = "serverName",

　　Port = 25, //匿名发送端口

　　EnableSsl = false,

　　DeliveryMethod = SmtpDeliveryMethod.Network,

　　UseDefaultCredentials = false,
