是否收到IIS重置通知？

Question

We have a system with a web app and a bunch of Windows Services doing some background work.

Whenever we need to make a more substantial change to the system, we end up having to issue an IIS Reset, and then manually restart all relevant Windows services.

Is there any way at all to be notified of such IISReset events in C# code, so that our Windows Services could restart themselves, whenever they detect such an IISReset command being executed?

Thanks! Marc

Answer 1

Couldn't you just write a batch file to call IIS Reset and then restart the Windows Services?

I think the way to start a Windows Service is:

NET START "SERVICE NAME"

Answer 2

Agree with Nebakanezer, you may need to stop the service first though.

• Option 1

NET STOP "SERVICE NAME"
NET START "SERVICE NAME"

• Option 2

What about deploying a dummy asp.net app to the IIS server, then you can detect the application starting which should only happen on an IISReset and trigger the stop and restart of the services? I'm not sure if IIS has a tightened security model that will allow you to do thinks like stop services or trigger a batch file to do same but it's worth a try.

• Option 3

If thats not an option for whatever reason, you could pull something together that monitors the IIS logs, I believe they log IIS resets.

Answer 3

You could also plug into Windows Instrumentation with you own custom Windows Query Language expression. I've never used it for IIS directly, but I expect that there would be objects you can listen to, which lets you be aware of such changes.
