asp发邮件算是会了，但是又来一个问题，向大家求助一下！

最近在做一个小程序，里面有关注册和找回密码的模块，都用到了发邮件。
但是就是有一个挠头的问题，发完邮件，邮件内容直接显示到页面上了，这哪行啊，我发的可是密码这种秘密信息啊，不能这样就显示出来吧...到底咋回事？
对了，我发的邮件内容是网页格式的，有没有关系啊?
下面是我的代码：
实现的功能是给用户邮箱发送重置密码邮件
首先是下面的发送的邮件内容，也就是下段代码中的Resetpwd.txt文件的文件内容



<style type="text/css" > 

<!-- 

body { 

background-image: url("http://hiphotos.baidu.com/zb_0527/pic/item/f7fac9ac19347dc4faed5012.jpg "); 

background-repeat:no-repeat; 

background-position:left top; 

background-attachment:fixed; 

} 

-- > 

</style > 



<html>

<head>

</head>

<body>

<div>

<p><b>

尊敬的用户

</b></p>

<br>

  <p><b>以下是重置后的密码，请在登录后及时更改</b></p>

<br>

  <p><font color="red">[NEWPWD]</font></a></p>

</div>

</body>

</html>





    string filename = "~/Resetpwd.txt";

    string emsubject =" 返回重置密码";

    sendEmail(em, emsubject, filename, newpwd);    



    public void sendEmail(string dEmail, string emSubject, string filename, string newpwd)

    {

        MailAddress emailFrom = new MailAddress("zb_527@sohu.com");

        MailAddress emailTo = new MailAddress(dEmail);



        MailMessage emailmsg = new MailMessage(emailFrom, emailTo);

        //优先级

        emailmsg.Priority = MailPriority.High;

        //邮件主题

        emailmsg.Subject = emSubject;

        emailmsg.BodyEncoding = System.Text.Encoding.UTF8;

        emailmsg.IsBodyHtml = true;



        string file = File.ReadAllText(Server.MapPath(filename), Encoding.GetEncoding("gb2312"));

        Response.Write(file);

        file = file.Replace("[NEWPWD]", newpwd);

        emailmsg.Body = file;



        SmtpClient client = new SmtpClient("smtp.sohu.com");

        client.Credentials = new System.Net.NetworkCredential("zb_527", "++++++");

        client.DeliveryMethod = SmtpDeliveryMethod.Network;

        //client.EnableSsl = true;



        try

        {

            client.Send(emailmsg);



            Response.Write("<script>alert('恭喜！重置密码成功，并已发送到您的邮箱中，请注意查收，及时修改密码！'）</script>");

            

            //MessageBoxButtons.YesNo;

            //mess

            //if()

        }

        //不能发送到收件人

        catch (SmtpFailedRecipientsException e)

        {

            for (int i = 0; i < e.InnerExceptions.Length; i++)

            {

                SmtpStatusCode status = e.InnerExceptions[i].StatusCode;

                if (status == SmtpStatusCode.MailboxBusy || status == SmtpStatusCode.MailboxUnavailable)

                {

                    Response.Write("<script>alert('发送失败，5分钟后重发!')</script>");

                    System.Threading.Thread.Sleep(3000);

                    client.Send(emailmsg);

                }

                else

                {

                    Response.Write("<script>alert('未知错误,未发送成功!')</script>");

                }

            }

        }

        catch (SmtpException e)

        {

            Response.Write("<script>alert('未知错误,未发送成功!')</script>");

        }

    }
