How can an NT Service cause itself to stop?

[dotnetprogrammer via DotNetMonster.com]

I have an NT Service written in c# (.net framwork 2.0). When it hits a
certain error condition, I want it to be to cause itself to stop. How can I
do this?

You could throw an exception, and it should stop then.

That's rather nasty no? How about this?:

new System.ServiceProcess.ServiceController("serviceName").Stop()

Calling this will throw an "invalidoperationexception" and logs a cryptic
error message in the eventlog, so should not be done. You better throw an
exception with a description of the error, this get's automatically logged
in the eventlog.

Not necessarily it won't. You'll need to check if 1) the service is running
and 2) the service can be stopped.

Otherwise the InvalidOperationException is thrown. The following works just
fine for me.

ServiceController controller = new System.ServiceProcess.ServiceController("Schedule");

bool isNotStopped = (controller.Status != ServiceControllerStatus.Stopped);

if( controller.CanStop && isNotStopped)
{
controller.Stop();
}

The ServiceController class is meant to 'connect/control' to existing
services, like I said it throws when you call Stop on an instance of the
(your own) running service. It works for you because "Schedule" is an
external service, but this is not what the OP asked for.
If your service needs to stop because it's no longer safe to continue, your
only option is to throw an exception with a message that gives a description
of the cause, this message will be logged in the eventlog.

Of course, you're right.

I totally missed that he needed to stop the currently running service.

..NET 2.0 added a Stop method to ServiceBase.

http://msdn2.microsoft.com/en-us/library/system.serviceprocess.servicebase.stop.aspx

You can use it to stop the currently executing service.
