ServiceHost.OnClosed Method

Disposes of disposable services that are being hosted when the service host is closed.

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

protected override void OnClosed()

When overriding the OnClosed method you must ensure the base.OnClosed method is called, even if an exception occurs. The following code illustrates how to do this.

protected override void OnClosed()
        if (FaultFlagService.faultFlag == ThrowDuring.OnClosed)
            FaultFlagService.faultFlag = ThrowDuring.Never;
            throw new ServiceActivationException("Faulting the service because FaultFlagService.faultFlag = ThrowDuring.OnClosed");
