求 asp.net 发送邮件的代码

http://blog.csdn.net/lff642/archive/2008/07/15/2654346.aspx
Google实例挺多的供LZ学习

代码很多，原理这个不是一句话就能说清楚的
代码直接baidu搜索
原理也一样看后实践即可

你的smtp服务器地址可用吗，试多几个地址看看

呵呵今天刚做了一个发送邮件的代码能用网上也很多这方面的东东 soso就知道了..

smtp地址我写的是smtp.163.com的
这样可以吗？
因为我也不知道这个应该怎么写了，还有它还要求端口号，是什么？

        {
            string str = se.Message;

        }
    }
}调用方法
Send(txtEmail.Text.Trim(), title.Text.Trim(), content.Text.Trim());

smtp.163.com 记得以前不支持非本地发邮件的吧...
smtp 端口一般是 25 pop3 好像是110

调用错误了！我的类是直接放在App_Code下的
正确调用SendMail st = new SendMail();
st.SendMails(txtEmail.Text.Trim(), title.Text.Trim(), content.Text.Trim());

Jmail发送，一个不错的方法：
需要引用jmail.dll组件，网上可以下载//发送邮件

        jmMessage.FromName = senderuser;
        jmMessage.Subject = subject;
        jmMessage.MailServerUserName = euser;
        jmMessage.MailServerPassWord = epwd;
        jmMessage.AddRecipient(receiver, "", "");
        if (this.upFile.PostedFile.ContentLength != 0)
        {
            string sFilePath = this.upFile.PostedFile.FileName;
            jmMessage.AddAttachment(@sFilePath, true, "");            string sfilepash2 = this.upFile2.PostedFile.FileName;
            jmMessage.AddAttachment(@sfilepash2, true, "");
         }
        jmMessage.Body = body;
        if (jmMessage.Send(eserver, false))
        {
             Response.Write("<script language=javascript>alert('发送成功')</script>");
        }
        else
        {
            Response.Write("<script language=javascript>alert('发送失败，请仔细检查邮件服务器的设置是否正确！')</script>");
            jmMessage = null;
            return;

            string content = "尊敬的:" + email + "您好！您填写的验证信息通过，我们已经帮您找回了密码，您的密码是: " + pwd;
            if (answer.ToString().Equals(answer) && result.ToString().Equals(result)) {

                //调用发送方法
                SendSMTPEMail(DropDownList2.SelectedValue, txtSendEmail.Text.Trim(),content);
            }
            Response.Write("<script>alert('邮件已经发送成功！请到您的邮箱去确认密码！');location.href='" + Request.Url.ToString() + "';</script>");
        }
        else

        }
}//发送邮件方法（发送者的服务器类型，接收者邮箱地址，发送的内容
