自动发送Email功能的代码示例

  通过.NET实现后台自动发送邮件功能的代码，可以将一些基础信息放到web.config文件中进行保存：
Web.config文件信息段：

<system.net>
<mailSettings>
<smtp deliveryMethod="Network" from=" yanggl@hotmail.com ">
<network host="smtp.hotmail.com" userName="yanggl@hotmail.com" password="" defaultCredentials="true" />
</smtp>
</mailSettings>
</system.net>

后台实现：

using System.Net.Mail;
using System.Configuration;
using System.Net.Configuration;
using System.Web.Configuration;
// addresses for send email.
string[] address = new string[] { "guilin_gavin@hotmail.com", "glyang@isoftstone.com" };
// email body.
string emailBody = "Hello! Guys!";
// email subject.
string subject = "This is a test!";
// get the config info.
SmtpSection smtpSection = NetSectionGroup.GetSectionGroup(WebConfigurationManager.OpenWebConfiguration("~/web.config")).MailSettings.Smtp;
// save the mail object.
MailMessage mm = new MailMessage();
foreach (string item in address)
     mm.To.Add(item);
mm.From = new MailAddress(smtpSection.From);
mm.BodyEncoding = System.Text.Encoding.UTF8;
mm.SubjectEncoding = System.Text.Encoding.UTF8;
mm.IsBodyHtml = true;
mm.Body = emailBody;
mm.Subject = subject;
// set and send email.
SmtpClient sc = new SmtpClient(smtpSection.Network.Host);
sc.DeliveryMethod = SmtpDeliveryMethod.Network;
sc.Credentials = new System.Net.NetworkCredential(smtpSection.Network.UserName, smtpSection.Network.Password);
sc.Send(mm);
