mailhelper  -------mail帮助类

复制代码 代码如下:

using system;
using system.collections.generic;
using system.linq;
using system.web;
using system.web.mail;

/// <summary>
///mailhelper 的摘要说明
/// </summary>
public class mailhelper
{
    public mailhelper()
    {
        //
        //todo: 在此处添加构造函数逻辑
        //
    }

    /// <summary>
    /// 邮件发送操作
    /// </summary>
    /// <param name="addressee">收件人地址</param>
    /// <param name="from">发件人地址</param>
    /// <param name="sendpassword">发件人密码</param>
    /// <param name="copy">抄送人地址</param>
    /// <param name="secret">密送人地址</param>
    /// <param name="subject">发送主题</param>
    /// <param name="attachment">附件信息</param>
    /// <param name="body">邮件内容</param>
    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

复制代码 代码如下:

<%@ 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:
复制代码 代码如下:

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;
}
