Question

每当我启动服务时，它都没有进行任何操作，因为服务不是＆＃34;发送邮件＆＃34;但是当我调试它的时候就像我预期的那样发送邮件。为什么它发生了我不知道。我认为这不是code.as编码在我调试时运行良好的问题。请建议我。

您可能想要检查权限。在什么帐户下运行服务？它是否有权访问文件系统？（也可能是邮件客户端的问题，但不太可能）

要检查此问题，添加try - 使用日志捕获代码。

这样的事情：

 using System;
public  class EnvVars
    {

        public static EnvVars GetSettings()
        {  
            EnvVars envVars = new EnvVars();

        try{
            //TODO - log begin work
        String[] files = Directory.GetFiles(@"H:\\EDI", "*.brl", SearchOption.AllDirectories);
        if (files.Length > 0)
        {
            var mail_server1 = ConfigurationManager.AppSettings.Get("mail_server");
            var mail_from_address1 = ConfigurationManager.AppSettings.Get("mail_from_address");

            var mail_address1 = ConfigurationManager.AppSettings.Get("mail_address");

            MailMessage mm = new MailMessage(mail_from_address1, mail_address1);

            mm.Body = ConfigurationManager.AppSettings.Get("body");

            mm.Subject = ConfigurationManager.AppSettings.Get("subject");

            mm.IsBodyHtml = true;

            int leng = files.Length;
            for (int i = 0; i < files.Length; i++)
           {
              String sep = "   |  ";

                String Body1 = String.Join(sep, files, 0, leng);
               mm.Body = Body1;
            }

            SmtpClient client = new SmtpClient(mail_server1);

                client.Send(mm);

        }
        }
            catch (Exception e)
        {

                //TODO - log exception
            }


        finally
        {
       return envVars;
        }
    }

}

}

可能在调试时，您的应用程序有足够的时间发送电子邮件。

将您的代码更改为此代码：

Task t = Task.Run(() => {
            EnvVars envVars = EnvVars.GetSettings();
            });
t.Wait();

每当我启动服务邮件没有发送但我什么时候调试它是按照我的预期发送邮件
