本文介绍如何在Windows服务中实现自定义命令处理。通过定义枚举类型来指定不同的自定义命令，并在服务中实现OnCustomCommand方法以响应这些命令。此外，还展示了如何从客户端应用程序调用这些自定义命令。

OnCustomCommand executes when the Service Control Manager (SCM) passes a custom command to the service. Specifies actions to take when a command with the specified parameter value occurs.

The only values for a custom command that you can define in your application or use in OnCustomCommand are those between 128 and 256.
Integers below 128 correspond to system-reserved values.

Create One Windows Service & Implement Below Code in Service :

namespace MyWindowsService
{
    public partial class Service1 : ServiceBase
    {
        public enum SimpleServiceCustomCommands { Command1 = 128, Command2 =129, Command3 = 130};

        public Service1()
        {
            InitializeComponent();
        }

        protected override void OnStart(string[] args)
        {
        }

        protected override void OnStop()
        {
        }

        protected override void OnCustomCommand(int command)
        {
            base.OnCustomCommand(command);

            switch(command)
            {
                case(int)SimpleServiceCustomCommands.Command1:
                //Command1 Implementation
                break;

                case(int)SimpleServiceCustomCommands.Command2:
                //Command2 Implementation
                 break;

                case(int)SimpleServiceCustomCommands.Command3:
                //Command3 Implementation
                    break;
                default:
                    break;

          }
        }
    } }

Call Windows Service CustomCommands From User Application :

Create Service Controller Object

ServiceController Controller = new ServiceController("MyWindowsService");
Start the Windows Service

Controller.Refresh(); //Gets the current status of service
    if (Controller.Status == ServiceControllerStatus.Stopped)
     {
Controller.Start();
     }
Call CustomCommands Using Controller Object

if (Controller.Status == ServiceControllerStatus.Running)
{
Controller.ExecuteCommand(128);
}
