下面的代码使用System.Net.Mail.MailMessage / System.Net.Mail.SmtpClient来发送来自Windows 2008R2上IIS7上运行的ASP.NET / C#3.5SP1应用程序的文件。即使我们3年多没有更改代码,它最近也开始发送重复的电子邮件。例如,如果me@me.com是currentVendor.Email,则me @me.com会收到完全相同的2封电子邮件。有任何想法吗? Windows Update会导致这种情况吗?
Vendor currentVendor = Vendor.GetCurrent();
string POLocation = Vendor.GetPOLocation();
#if !DEBUG
MailMessage mailer = new MailMessage("orders@perks.com", "resdev@perks.com");
string[] addresses = currentVendor.Email.Split(new char[] { ';', ',' });
foreach (string recip in addresses)
{
mailer.To.Add(recip.Trim());
}
#else
MailMessage mailer = new MailMessage("orderstest@me.com", "devtest@me.com");
#endif
mailer.Subject = String.Format("{0} V2 Purchase Orders - {1}", currentVendor.Name, DateTime.Today.ToShortDateString());
mailer.IsBodyHtml = true;
mailer.Body = "Please find attached..... <br/>" +
"This email is system generated. If you have any trouble please, contact us";
mailer.Attachments.Add(new Attachment(POLocation));
SmtpClient mailClient = new SmtpClient();
mailClient.Send(mailer);
提前致谢!
答案 0 :(得分:0)
尝试检查此代码:
Vendor currentVendor = Vendor.GetCurrent();
不会返回重复的电子邮件地址?
只有一次调用MailClient.Send()方法:
mailClient.Send(mailer);
但请确保您没有多次调用已粘贴的整个代码段!
