Comentarios

Cuando se llama a ExecuteCommand , el estado del servicio no cambia.When you call ExecuteCommand, the status of the service does not change. Si se inició el servicio, el estado permanece Running .If the service was started, the status remains Running. Si el servicio se ha detenido, el estado permanece Stopped , y así sucesivamente.If the service was stopped, the status remains Stopped, and so on. Para procesar el comando personalizado, el servicio debe invalidar el OnCustomCommand método y proporcionar un controlador para el comando identificado por el command parámetro.To process the custom command, the service must override the OnCustomCommand method and provide a handler for the command identified by the command parameter.
