Before calling Service.Stop

Question

Before calling Service.Stop

StewartBW 1,720

Hi experts,

Using MyService As New ServiceController("BlahService")
  If MyService.CanStop = True AndAlso MyService.Status = ServiceControllerStatus.Running Then MyService.Stop()
  MyService.Close()
End Using

Is my usage correct? I mean before calling Service.Stop should I check both for Service.CanStop and Service.Status? Thanks.

Your intention is mostly correct, but looks like there's a logical mistake in your condition. You're checking:

MyService.CanStop = True AndAlso MyService.Status <> ServiceControllerStatus.Running

This means only stop the service if it can be stopped AND it's not running, which doesn't seem to make much sense, because ServiceController.Stop() only applies to a running service. Instead, you should only stop the service if it's running and can be stopped. So, your condition should be:

If MyService.CanStop AndAlso MyService.Status = ServiceControllerStatus.Running Then
    MyService.Stop()
End If
