Managed C++中的ServiceController？ （.NET）

Question

嗨im試圖通過.NET應用程序啓動/停止/禁用Windows服務，但我似乎無法得到下面的代碼工作，它一直說錯誤4錯誤C2065：'ServiceController'：未聲明的標識符

這是什麼正確的參考？我似乎無法找到正確的一個在系統::

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，所以我修改了代碼，它現在編譯，但拋出一個「對象引用不設置到對象的實例」錯誤

    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); 
     } 

     }

您有使用過關於System::ServiceProcess嗎？如果不是，你將不得不完全符合System::ServiceProcess::ServiceController的資格。此外，您必須包含對System.ServiceProcess.dll程序集的引用。您可以通過從項目的右鍵單擊上下文菜單中選擇「屬性」來添加引用。然後從左側樹形視圖頂部選擇「Common Properties」。點擊「添加新參考...」按鈕並選擇適當的參考。或者，你可以右鍵點擊該項目，並選擇「引用...」
