Executes a custom command on the service.

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

public void ExecuteCommand (
	int command
public void ExecuteCommand (
	int command
public function ExecuteCommand (
	command : int
Not applicable.



An application-defined command flag that indicates which custom command to execute.

Exception typeCondition


An error occurred when accessing a system API.


The service cannot handle the custom command.

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.

using System;
using System.ServiceProcess;

namespace test_exec_cmnd
    class Program
        private enum SimpleServiceCustomCommands { StopWorker = 128, RestartWorker, CheckWorker };
        static void Main(string[] args)
            ServiceController myService = new ServiceController("SimpleService");
