ServiceBase.OnPowerEvent Method

When implemented in a derived class, executes when the computer's power status has changed. This applies to laptop computers when they go into suspended mode, which is not the same as a system shutdown.

Namespace:  System.ServiceProcess
Assembly:  System.ServiceProcess (in System.ServiceProcess.dll)

abstract OnPowerEvent : 
        powerStatus:PowerBroadcastStatus -> bool  
override OnPowerEvent : 
        powerStatus:PowerBroadcastStatus -> bool

Parameters

powerStatus
Type: System.ServiceProcess.PowerBroadcastStatus

A PowerBroadcastStatus that indicates a notification from the system about its power status.

Return Value

Type: System.Boolean
When implemented in a derived class, the needs of your application determine what value to return. For example, if a QuerySuspend broadcast status is passed, you could cause your application to reject the query by returning false.

Use OnPowerEvent to specify the processing that occurs when the system event indicated in the PowerBroadcastStatus enumeration occurs--for example, when the computer is placed in suspended mode or indicates low battery power.

OnPowerEvent is expected to be overridden when the CanHandlePowerEvent property is true.
