添加引用
using System.Net.Mail;
using System.Net;
实例化：MailMessage mmsg = new MailMessage();
/// <summary> ///发送电子邮件 /// </summary> /// <param name="sendEmailAddress">发件人邮箱地址</param> /// <param name="sendEmailPwd">发件人邮箱密码授权码</param> /// <param name="msgToEmail">收件人邮箱地址</param> /// <param name="title">邮箱标题</param> /// <param name="content">邮件内容</param> /// <param name="host">邮箱服务器</param> /// <returns></returns> public int SendEmail(string sendEmailAddress, string sendEmailPwd, string msgToEmail, string title, string content, stringhost) { //发件者邮箱地址 string fjrtxt =sendEmailAddress; //发件者邮箱密码 string mmtxt =sendEmailPwd; //主题 string zttxt =title; //内容 string nrtxt =content; string[] fasong = fjrtxt.Split('@'); //设置邮件协议 SmtpClient client = newSmtpClient(host); client.EnableSsl = true; client.UseDefaultCredentials = false; //通过网络发送到Smtp服务器 client.DeliveryMethod =SmtpDeliveryMethod.Network; //通过用户名和密码 认证 client.Credentials = new NetworkCredential(fasong[0].ToString(), mmtxt); //发件人和收件人的邮箱地址 //MailMessage mmsg = new MailMessage(); //表示电子邮件: MailMessage mmsg.From = new MailAddress(fjrtxt); //邮件地址 ：MailAddress mmsg.To.Add(newMailAddress(msgToEmail)); //邮件主题 mmsg.Subject =zttxt; //主题编码 mmsg.SubjectEncoding =Encoding.UTF8; //邮件正文 mmsg.Body =nrtxt; //正文编码 mmsg.BodyEncoding =Encoding.UTF8; //设置为HTML格式 mmsg.IsBodyHtml = true; //优先级 mmsg.Priority =MailPriority.High; try{ client.Send(mmsg); return 1; } catch{ return 0; } }
上传附件
private void 上传附件button1_Click(objectsender, EventArgs e) { //MailMessage mm = new MailMessage(); OpenFileDialog openFile = newOpenFileDialog(); if (openFile.ShowDialog() ==System.Windows.Forms.DialogResult.OK) { mmsg.Attachments.Add(newAttachment(openFile.FileName)); this.fujian.Text =openFile.FileName; } }
发送按钮
private void 发送button2_Click(objectsender, EventArgs e) { int mesAge = SendEmail(fajianren.Text, mima.Text, shoujianren.Text, biaoti.Text, neirong.Text, "smtp.qq.com");//mima就是授权码 if (mesAge == 1) MessageBox.Show("发送成功！"); elseMessageBox.Show("发送失败！"); }
