accessing 'start parameters', debugging topshelf and programmatically stopping

[Neil Walker]

Hello,

I've spent some time setting things up that seem to work very nicely, but it was painful without being able to debug. Anyway, can anyone help with the following as after a few days playing this is my only outstanding issues:

1. I added command line support as follows:

             HostFactory.Run(hostConfigurator =>

            {

                hostConfigurator.AddCommandLineDefinition("params", f => { startParams = f; });

                hostConfigurator.ApplyCommandLine(); 

Which is fine from the commandline, but I wish to access something similar from the running service. I assumed the 'start parameters' option in the service dialog would equate to the same thing, but it's not. Can somebody tell me how to access 'start parameters' please?

2. I wish to programmatically stop the service, but I can't see how. Is there a way? I can throw and exception but that doesn't look nice and it's always 'error 5: access denied'?

3. How do I debug the program running as a service? my program initially crashed in startup or just after it started so attaching the debugger doesn't help, I want to be able to run the program from within Visual Studio as a service. Or if not, maybe just how to attach the debugger before it starts processing would help.

Thanks for your help.

Neil.

If it runs properly from visual studio or the command-line, but crashes as a service, it's ALMOST ALWAYS security permissions related. There should be other articles about how to debug a service startup, debugging Topshelf running as a service should be the same.

Ok. So how do I stop it programmatically? no matter what I do it just sits there (in console) with the message 'press ctrl-c' and I cannot find any way to kill it other than an unhandled exception.

You can press Control+C, or you can call HostControl.Stop() (the hostControl instance is passed to both the start and stop methods on the service itself).
