C#邮件发送
这篇文章主要介绍如何使用C#的MailAddress类进行邮件的发送。
1.首先引入命名空间using System.Net.Mail;
2.将发送的邮件的功能封装成一个类，该类中包含了发送邮件的基本功能：收件人(多人)，抄送(多人)，发送人，主题，邮件正文，附件等，封装的Email类如下：
public class Email{/// <summary>/// 发送者/// </summary>public string mailFrom { get; set; }/// <summary>/// 收件人/// </summary>public string[] mailToArray { get; set; }/// <summary>/// 抄送/// </summary>public string[] mailCcArray { get; set; }/// <summary>/// 标题/// </summary>public string mailSubject { get; set; }/// <summary>/// 正文/// </summary>public string mailBody { get; set; }/// <summary>/// 发件人密码/// </summary>public string mailPwd { get; set; }/// <summary>/// SMTP邮件服务器/// </summary>public string host { get; set; }/// <summary>/// 正文是否是html格式/// </summary>public bool isbodyHtml { get; set; }/// <summary>/// 附件/// </summary>public string[] attachmentsPath { get; set; }public bool Send(){//使用指定的邮件地址初始化MailAddress实例MailAddress maddr = new MailAddress(mailFrom);//初始化MailMessage实例MailMessage myMail = new MailMessage();//向收件人地址集合添加邮件地址if (mailToArray != null){for (int i = 0; i < mailToArray.Length; i++){myMail.To.Add(mailToArray[i].ToString());}}//向抄送收件人地址集合添加邮件地址if (mailCcArray != null){for (int i = 0; i < mailCcArray.Length; i++){myMail.CC.Add(mailCcArray[i].ToString());}}//发件人地址myMail.From = maddr;//电子邮件的标题myMail.Subject = mailSubject;//电子邮件的主题内容使用的编码myMail.SubjectEncoding = Encoding.UTF8;//电子邮件正文myMail.Body = mailBody;//电子邮件正文的编码myMail.BodyEncoding = Encoding.Default;myMail.Priority = MailPriority.High;myMail.IsBodyHtml = isbodyHtml;//在有附件的情况下添加附件try{if (attachmentsPath != null && attachmentsPath.Length > 0){Attachment attachFile = null;foreach (string path in attachmentsPath){attachFile = new Attachment(path);myMail.Attachments.Add(attachFile);}}}catch (Exception err){throw new Exception("在添加附件时有错误:" + err);}SmtpClient smtp = new SmtpClient();//指定发件人的邮件地址和密码以验证发件人身份smtp.Credentials = new System.Net.NetworkCredential(mailFrom, mailPwd);//设置SMTP邮件服务器smtp.Host = host;try{//将邮件发送到SMTP邮件服务器 smtp.Send(myMail);return true;}catch (System.Net.Mail.SmtpException ex){return false;}}}
3.页面调用发送邮件的类
protected void Send_Click(object sender, EventArgs e){Email email = new Email();email.mailFrom = "发送人的邮箱地址";email.mailPwd = "发送人邮箱的密码";email.mailSubject = "邮件主题";email.mailBody = "邮件内容";email.isbodyHtml = true; //是否是HTMLemail.host = "smtp.126.com";//如果是QQ邮箱则：smtp:qq.com,依次类推email.mailToArray = new string[] { "******@qq.com","12345678@qq.com"};//接收者邮件集合email.mailCcArray = new string[] { "******@qq.com" };//抄送者邮件集合if (email.Send()){Response.Write("<script type='text/javascript'>alert('发送成功！');history.go(-1)</script>");//发送成功则提示返回当前页面； }else{Response.Write("<script type='text/javascript'>alert('发送失败！');history.go(-1)</script>");}}
以上就完成了在C#中如何发送邮件。
