When implemented in a derived class, executes when a Stop command is sent to the service by the Service Control Manager (SCM). Specifies actions to take when a service stops running.
Namespace: System.ServiceProcess Assembly: System.ServiceProcess (in system.serviceprocess.dll)
Use OnStop to specify the processing that occurs when the service receives a Stop command.
When the SCM receives a Stop command, it uses the value of CanStop to verify whether the service accepts Stop commands. If CanStop is true, the Stop command is passed to the service, and the OnStop method is called if it is defined. If OnStop is not implemented in the service, the SCM handles the Stop command.
If CanStop is false, the SCM ignores the Stop command. It is not passed to the service. The Stop command returns and throws an exception.
OnStop is expected to be overridden in the derived class. For the service to be useful, OnStart and OnStop should both be implemented in your service class.
