When you call ExecuteCommand, the status of the service does not change. If the service was started, the status remains Running. If the service was stopped, the status remains Stopped, and so on. To process the custom command, the service must override the OnCustomCommand method and provide a handler for the command identified by the command parameter.
The following code example shows the use of the ServiceController.ExecuteCommand method to execute custom commands in the SimpleService service example. See the ServiceBase class for the sample code for the SimpleService service.
