C#_发送邮件

你要用QQ邮件发邮件就配置邮件服务器为QQ邮箱的邮件服务器mail.qq.com.然后FromAddress那里配置成你的邮件地址，objSmtpClient.Credentials 需要你的邮箱和密码。方法  SendMail(string mailAddress, string mailTitle, string mailContent)需要参数mailAddress为你要发送的邮箱地址，mailTitle为邮件主题，mailContent为邮件内容。还需要引用：using System.Net.Mail;

public static void SendMail(string mailAddress, string mailTitle, string mailContent)       {           MailMessage objMailMessage = new MailMessage();           string fromAddress = ConfigurationManager.AppSettings["FromAddress"];//你在web.config中配置的发件人地址，就是你的邮箱地址。           string mailHost = ConfigurationManager.AppSettings["MailHost"];//邮件服务器，如mail.qq.com

           objMailMessage.From = new MailAddress(fromAddress);//发送方地址           objMailMessage.To.Add(new MailAddress(mailAddress));//收信人地址           objMailMessage.BodyEncoding = System.Text.Encoding.UTF8;//邮件编码           objMailMessage.Subject = mailTitle;//邮件标题           objMailMessage.Body = mailContent;//邮件内容           objMailMessage.IsBodyHtml = true;//邮件正文是否为html格式

           SmtpClient objSmtpClient = new SmtpClient();           objSmtpClient.Host = mailHost;//邮件服务器地址           objSmtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;//通过网络发送到stmp邮件服务器           objSmtpClient.Credentials = new System.Net.NetworkCredential();//发送方的邮件地址，密码           //objSmtpClient.EnableSsl = true;//SMTP 服务器要求安全连接需要设置此属性

           try           {               objSmtpClient.Send(objMailMessage);           }           catch (Exception ex)           {               LogHelper.WriteLog(LogFile.Error, ex.ToString());//记录错误日志           }       }
