检查服务是否正在使用Win32_Service运行

Question

I have a very quick question about Win32_Service

Is

String sState = service["State"].ToString();
if (! sState.Equals("Running"))

Sufficent to moniter if a service is not running? I want the if statement to return true in all cases where the service isn't running so it can send a warning message.

Answer 1

Windows service states are:

• SERVICE_STOPPED . Service is not running.
• SERVICE_START_PENDING . Service is starting (but you can assume that it is not running. Hopefully the service will start soon)
• SERVICE_STOP_PENDING . Service is stopping. (but you can assume that it is still running, except possibly the only thing service is doing is finishing in an orderly manner, disregarding any external request)
• SERVICE_RUNNING . Service is running (and ready to meet external requests)
• SERVICE_CONTINUE_PENDING . Similar to START_PENDING . Hopefully the service will start soon.
• SERVICE_PAUSE_PENDING . Service is going to be paused in the near future.
• SERVICE_PAUSED . Service is paused

The only state that guarantees that the service is running is SERVICE_RUNNING , but I would not display a warning if the service is in state START_PENDING . At least, show different warnings depending on the state.

HTH.
