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：

代码<system.net>

<mailSettings>

<smtp deliveryMethod="Network" from=" [email protected] ">

<network host="smtp.hotmail.com" userName="[email protected]" password="" defaultCredentials="true" />

</smtp>

</mailSettings>

</system.net>

后台实现：

代码using System.Net.Mail;

using System.Configuration;

using System.Net.Configuration;

using System.Web.Configuration;

// addresses for send email.

string[] address = new string[] { "[email protected]", "[email protected]" };

// 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);
