asp.net 发送邮件

crm 需要推送邮件,网上搜了搜----

直接上代码

mailhelper  -------mail帮助类

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Mail;



/// <summary>

public class mailhelper

{

    public mailhelper()

    {

        //

        //TODO: 在此处添加构造函数逻辑

        //

    }



    /// <summary>

    public string SendeEmal(string Addressee, string From, string sendpassword, string Copy, string secret, string Subject, string Attachment, string Body)

    {

        MailMessage objMailMessage;

        MailAttachment objMailAttachment;





        // 创建邮件消息

        objMailMessage = new MailMessage();



        //发件人EMAIL

        objMailMessage.From = From;//源邮件地址



        //收件人EMAIL

        objMailMessage.To = Addressee; //目的邮件地址

        //邮件抄送

        objMailMessage.Cc = Copy;

        //邮件misong

        objMailMessage.Bcc = secret;





        //邮件主题

        objMailMessage.Subject = Subject; //发送邮件的标题



        //邮件内容

        objMailMessage.Body = Body;//发送邮件的内容



        // 创建一个附件对象

        if (Attachment != "")

        {

            objMailAttachment = new MailAttachment(Attachment);//发送邮件的附件 c:\\test.txt

            objMailMessage.Attachments.Add(objMailAttachment);//将附件附加到邮件消息对象中

        }



        //接着利用SMTP来发送邮件,需要使用Microsoft .NET Framework SDK v1.1和它以上的版本

        //基本权限

        objMailMessage.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1");

        //用户名

        string name = From.Substring(0, From.IndexOf('@'));

        objMailMessage.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", name);

        //密码

        objMailMessage.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", sendpassword);

        //如果没有上述三行代码,则出现如下错误提示:服务器拒绝了一个或多个收件人地址。服务器响应为: 554 : Client host rejected: Access denied

        //SMTP地址      

        string smtp = "smtp." + From.Substring(From.IndexOf('@') + 1);

        SmtpMail.SmtpServer = "smtp." + From.Substring(From.IndexOf('@') + 1);

        //开始发送邮件



        try

        {

            SmtpMail.Send(objMailMessage);

            return "邮件发送成功!";

        }

        catch (System.Net.Mail.SmtpException ex)

        {

            return ex.Message;

        }

        //核心代码结束

    }

}

然后下来是自己做的一个demo--

前台:

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

    ValidateRequest="false" %>



<!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>

    <script src="../Style/jquery/jquery.js" type="text/javascript"></script>

    <script src="../Style/jquery/jquery.validate.js" type="text/javascript"></script>

    <script language="javascript" type="text/javascript">



        function gei() {

            var file_value = document.getElementById("File1").value;

            document.getElementById("HiddenField1").value = file_value;

        }

    </script>

</head>

<body>

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

    <div>

        发给:<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox><br />

        抄送:<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox><br />

        密送:<asp:TextBox ID="TextBox4" runat="server"></asp:TextBox><br />

        主题:<asp:TextBox ID="TextBox5" runat="server"></asp:TextBox><br />

        内容:<asp:TextBox ID="TextBox3" runat="server"></asp:TextBox><br />

        附件:<input id="File1" type="file" />

        <%--<asp:TextBox ID="TextBox6" runat="server"></asp:TextBox>--%>

        <br />

        <asp:Button ID="Button1" runat="server" Text="发送" OnClientClick="gei()" OnClick="Button1_Click" /><br />

        <asp:Label ID="Label1" runat="server" Text=""></asp:Label>

    </div>

    <asp:HiddenField ID="HiddenField1" runat="server" />

    </form>

</body>

</html>

后台:

protected void Button1_Click(object sender, EventArgs e)

    {



        

        //实例邮件帮助类

        mailhelper mails = new mailhelper();



        string filePath = HiddenField1.Value;



        string a = mails.SendeEmal(TextBox1.Text, "邮件账号", "邮件密码", TextBox2.Text, TextBox4.Text, TextBox5.Text, filePath, TextBox3.Text);



        Label1.Text = a;







    }

知道自己还得再这条路上走,好好积累吧。眨眼
