asp.net发送邮件示例分享
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;
/// ///mailhelper 的摘要说明/// public class mailhelper{ public mailhelper() { // //TODO: 在此处添加构造函数逻辑 // }
/// /// 邮件发送操作 /// /// 收件人地址 /// 发件人地址 /// 发件人密码 /// 抄送人地址 /// 密送人地址 /// 发送主题 /// 附件信息 /// 邮件内容 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" %>
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;}
