本文介绍了一个使用 C# 实现的简单邮件发送功能，通过 SmtpClient 和 MailMessage 类来完成邮件的发送过程。该代码示例展示了如何从配置中读取 SMTP 服务器设置、邮件账户信息，并实现邮件内容的填充及附件的添加。

代码

  private void btnSend_Click(object sender, EventArgs e)
        {
            SettingsBiz settings = new SettingsBiz();
            string smtp = settings.GetSettingsValue(FormEmailSettings.Mail_SMTP, Globals.CurrentSeatId);
            string from = settings.GetSettingsValue(FormEmailSettings.Mail_From, Globals.CurrentSeatId);
            string username = settings.GetSettingsValue(FormEmailSettings.Mail_UserName, Globals.CurrentSeatId);
            string password = settings.GetSettingsValue(FormEmailSettings.Mail_Password, Globals.CurrentSeatId);

            string title = txtTitle.Text.Trim();
            string to = from;
            string shoujianren = txtName.Text.Trim();//收件人
            string body = txtContent.Text.Trim() ;

            UsersTableAdapter adp = new UsersTableAdapter();
            string realname = adp.GetDataByUserId(Globals.CurrentSeatId).Single().Realname;

            MailMessage mailMsg = new MailMessage();//MailMessage mailMsg = new MailMessage();//两个类，别混了引入System.Web这个Assembly
            mailMsg.From = new MailAddress(from, "XXXXXX集团客服中心(" + realname + ")");//源邮件地址
            mailMsg.To.Add(new MailAddress(to, shoujianren));//目的邮件地址。可以有多个收件人
            mailMsg.Subject = title;//发送邮件的标题
            mailMsg.Body = body;//发送邮件的内容
            string filename = txtFujian.Text.Trim();
            if (!string.IsNullOrEmpty(filename))
            {
                mailMsg.Attachments.Add(new Attachment(filename));//将附件附加到邮件消息对象中，可以有多个附件。
            }

            SmtpClient client = new SmtpClient(smtp);
            client.Credentials = new NetworkCredential(from, password);
            client.Send(mailMsg);
            MessageBox.Show("发送成功");
        }
