asp.net 发送邮件问题

party620 2013-07-16 04:14:55

我在网站找的代码测试，有错不知道如何修改，请帮忙！！！

在设计页面;

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="sendEmail.aspx.cs" Inherits="sendEmail" %>



<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">



<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

    <title></title>

</head>

<body>

    <form id="form1" runat="server">

    <div>

       邮箱地址：  <asp:TextBox ID="txtaddress" runat="server"></asp:TextBox> <br /> <br />

       抄送志： <asp:TextBox ID="txtto" runat="server"></asp:TextBox><br /> <br />

        邮件主题： <asp:TextBox ID="txttitle" runat="server"></asp:TextBox><br /> <br />

         邮件内容： <asp:TextBox ID="txtcontent" runat="server"></asp:TextBox><br /> <br />

        <asp:Button ID="btn1" runat="server" Text="发送" onclick="btn1_Click" />





    </div>

    </form>

</body>

</html>

在后台：

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Net.Mail;

using System.Net;



public partial class sendEmail : System.Web.UI.Page

{

    protected void Page_Load(object sender, EventArgs e)

    {



    }

    protected void btn1_Click(object sender, EventArgs e)

    {

        MailMessage mymail = new MailMessage();



        mymail.From = new MailAddress("18301584131@163.com");

        mymail.To.Add(new MailAddress(this.txtaddress.Text));

        mymail.Subject = this.txttitle.Text;

        mymail.SubjectEncoding = System.Text.Encoding.UTF8;

        mymail.Body = this.txtcontent.Text;

        mymail.CC.Add(new MailAddress(this.txtaddress.Text));



        mymail.IsBodyHtml = true;

        mymail.Priority = MailPriority.Normal;



        //创建一个邮件服务器类



        SmtpClient myclient = new SmtpClient();

       // myclient.Host = "SMTP.163.com";

        myclient.Port = 25;



        myclient.Credentials = new NetworkCredential("18301584131@163.com", "zxt52133122");



        myclient.Send(mymail);



    }

}

每次会出现：

什么原因？？？而且myclient.Credentials = new NetworkCredential("18301584131@163.com", "zxt52133122");里面的邮箱地址是发件人的邮箱吗？

 string user = "18301584131@163.com";
        string pwd = "zxt52133122";
        string smtpServer = "SMTP.163.com";
        MailMessage message = null;
        MailAddress from = new MailAddress(user);
        MailAddress to = new MailAddress(user);
        message = new MailMessage(from, to);
        message.Priority = MailPriority.Normal;
        message.Subject = "邮件标题";
        message.IsBodyHtml = true;
        message.Body = "test";
        SmtpClient client = new SmtpClient();//smtpServer, 25
        client.Host = smtpServer;
        client.Port = 25;
        client.DeliveryMethod = SmtpDeliveryMethod.Network;
        client.Credentials = new System.Net.NetworkCredential(user, pwd);
        client.Send(message);

看下上边的能否发送， myclient.Credentials = new NetworkCredential("18301584131@163.com", "zxt52133122"); 是发件人的用户密码

收到邮件啦

哦，弱弱的问一下，这根电脑上网有关系吗？

上网是必须的，这又不是离线的。你应该测试一下，登录你的qq邮箱，看能否发送到163邮箱，然后登录163邮件，看能否查看。

smtp协议时简单邮件传输协议，必须要开启否则无法发送。 pop3是接收邮件用到的协议，否则无法接收邮件。
