使用 Topshelf 时服务没有及时响应启动或控制请求

Question

I am trying to create a top-shelf service that depends on input from the command line. But when using the configuration of the command line argument the service can't "start in a timely fashion".

My configuration of the service:

If I remove the configuration of the language setting and hard code the value, the service starts just fine... Any ideas?

HostFactory.Run(conf =>
{
CultureInfo language = null; 

conf.AddCommandLineDefinition("language", lang => { language = new CultureInfo(lang); });
conf.ApplyCommandLine();
var countryCode = new RegionInfo(language.Name).TwoLetterISORegionName.ToUpper();
conf.SetDescription("{0} Order Broker".FormatWith(countryCode));
conf.SetDisplayName("{0} Order Broker".FormatWith(countryCode));
conf.SetServiceName("{0}OrderBroker".FormatWith(countryCode));

conf.StartAutomatically();
conf.RunAsLocalSystem();
conf.Service<IOrderService>(svc =>
{
   svc.ConstructUsing(name => Creator.Current.Create<IOrderService>());
   svc.WhenStarted(service => service.Start(language));
   svc.WhenStopped(service => service.Stop());
});
});

Here's the stacktrace:

System.ComponentModel.Win32Exception: The service did not respond to the start
or control request in a timely fashion --- End of inner exception stack trace ---
at System.ServiceProcess.ServiceController.Start(String[] args)
at System.ServiceProcess.ServiceController.Start()

Answer 1

So the problem here is that language isn't provided when it starts as a service. You'd need to edit the image-path for the service to include that command line parameter. I think you're much better off reading that from the app.config.
