ServiceController.ExecuteCommand Method

Executes a custom command on the service.

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

public void ExecuteCommand(
	int command
)

Parameters

command
Type: System.Int32

An application-defined command flag that indicates which custom command to execute. The value must be between 128 and 256, inclusive.

ExceptionCondition
Win32Exception

An error occurred when accessing a system API.

InvalidOperationException

The service was not found.

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(Int32) method to execute custom commands in the SimpleService service example.

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");
            myService.ExecuteCommand((int)SimpleServiceCustomCommands.StopWorker);
            myService.ExecuteCommand((int)SimpleServiceCustomCommands.RestartWorker);
            myService.ExecuteCommand((int)SimpleServiceCustomCommands.CheckWorker);


        }
    }
}
