Managed C++中的ServiceController？ （.NET）

Question

嗨im试图通过.NET应用程序启动/停止/禁用Windows服务，但我似乎无法得到下面的代码工作，它一直说错误4错误C2065：'ServiceController'：未声明的标识符

这是什么正确的参考？我似乎无法找到正确的一个在系统::

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);  

行，所以我修改了代码，它现在编译，但抛出一个“对象引用不设置到对象的实例”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); 
     } 

     }

您有使用过关于System::ServiceProcess吗？如果不是，你将不得不完全符合System::ServiceProcess::ServiceController的资格。此外，您必须包含对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“属性”来添加引用。然后从左侧树形视图顶部选择“Common Properties”。点击“添加新参考...”按钮并选择适当的参考。或者，你可以右键点击该项目，并选择“引用...”
