托管c++中的ServiceController？(.NET)

Question

您好，我试图通过.NET应用程序启动/停止/禁用windows服务，但我似乎无法获得以下代码工作，它一直在说错误4错误C2065：'ServiceController‘：未声明的标识符

这方面的正确参考是什么？我似乎在系统中找不到正确的：

String ^servicename = "srservice";



             // Stop the service if it's started.

             ServiceController^ controller = new ServiceController(servicename);
             if (controller.Status == ServiceControllerStatus.Running)

                 controller.Stop();



             // Set the startup type of the service.

             String^ serviceregistrylocation = String::Format("SYSTEM\CurrentControlSet\Services\{0}", servicename);

             RegistryKey ^localMachine = Registry::LocalMachine;

             RegistryKey servicekey = localMachine.OpenSubKey(serviceregistrylocation, true);



             // Set value to 2 for automatic, 3 for manual, or 4 for disabled.

             servicekey.SetValue("Start", 3);       

好的，所以我修改了代码，它现在编译了，但是抛出了一个"object reference not set to an object instance of an object“错误

                 String ^servicename = "Fax";



             // Stop the service if it's started.

             ServiceController^ controller = gcnew ServiceController(servicename);
             if (controller->Status == ServiceControllerStatus::Running)

                 controller->Stop();



             // Set the startup type of the service.

             String^ serviceregistrylocation = String::Format("SYSTEM\CurrentControlSet\Services\{0}", servicename);

             RegistryKey ^localMachine = Registry::LocalMachine;

             RegistryKey ^servicekey = localMachine->OpenSubKey(serviceregistrylocation, true);



             // Set value to 2 for automatic, 3 for manual, or 4 for disabled.
             try{
             servicekey->SetValue("Start", 4);
             }
                 catch ( Exception^ e ) 
        {
            MessageBox::Show( e->Message );
        }

         }

Answer 1

你有System::ServiceProcess的using语句吗？如果不是，则必须使用System::ServiceProcess::ServiceController完全限定该类。此外，还必须包含对System.ServiceProcess.dll程序集的引用。您可以通过从项目的右键单击上下文菜单中选择Properties来添加引用。然后从左侧树视图的顶部选择"Common Properties“。单击“添加新引用...”按钮，然后选择适当的引用。或者，您可以右键单击项目并选择“引用...”
