执行命令servicecontroller - 无法在服务上执行命令

标签: c# servicecontroller

我正在使用服务控制器executecommand函数,如下所示:

            ServiceController serviceController = new ServiceController("a Service",
                Environment.MachineName);

            serviceController.ExecuteCommand(129);

在服务控制器中:

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

        // Depending on the integer passed in, the appropriate method is called.
        switch (command)
        {
            case 129:
                RestartSpooler();
                break;
            case 131:
                InstallPrinter();
                break;
            case 132:
                DeletePrinter();
                break;
        }
    }

然而,尽管调用了调用代码中的任何命令(代码命中行,然后跳过,没有例外),但没有任何反应。为什么?这都在本地机器上,我有完全的管理权限。

您必须尝试对已停止的服务执行命令。添加如下内容:

    if (serviceController1.Status == ServiceControllerStatus.Stopped)
    {
        serviceController1.Start();
    }
    serviceController1.ExecuteCommand(192);

我没有找到任何理由不应该起作用。 以下是使用自定义命令

的Windows服务的工作示例
public partial class TestService : ServiceBase
{
    public TestService()
    {
        InitializeComponent();
    }

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

    protected override void OnStop() { }

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

        switch (command)
        {
            case 129:
                //
                break;
            case 131:
                //
                break;
            case 132:
                //
                break;
        }
    }
}

服务安装程序

[RunInstaller(true)]
public partial class Installer : System.Configuration.Install.Installer
{
    public Installer()
    {
        InitializeComponent();

        _processInstaller = new ServiceProcessInstaller();
        _processInstaller.Account = ServiceAccount.LocalSystem;

        _serviceInstaller = new ServiceInstaller();
        _serviceInstaller.StartType = ServiceStartMode.Manual;
        _serviceInstaller.ServiceName = "TestService";

        Installers.Add(_serviceInstaller);
        Installers.Add(_processInstaller);
    }

    private readonly ServiceInstaller _serviceInstaller;
    private readonly ServiceProcessInstaller _processInstaller;
}

服务使用

var serviceController = new ServiceController("TestService", Environment.MachineName);
serviceController.ExecuteCommand(129);
