mailhelper -------mail帮助类
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
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：
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;
}
