示例

以下示例使用 ServiceController 类在本地计算机上显示设备驱动程序服务。

array<ServiceController^>^scDevices = ServiceController::GetDevices();
if ( scDevices->Length )
{
   int numAdapter = 0,numFileSystem = 0,numKernel = 0,numRecognizer = 0;

   // Display the list of device driver services.
   Console::WriteLine(  "Device driver services on the local computer:" );

   for each (ServiceController^ scTemp in scDevices)
   {
      // Display the status and the service name, for example,
      //   [Running] PCI Bus Driver
      //             Type = KernelDriver
      Console::WriteLine(  " [{0}] {1}", scTemp->Status, scTemp->DisplayName );
      Console::WriteLine(  "           Type = {0}", scTemp->ServiceType );

      // Update counters using the service type bit flags.
      if ( (scTemp->ServiceType & ServiceType::Adapter) != (ServiceType)0 )
      {
         numAdapter++;

注解

GetDevices 仅从本地计算机返回设备驱动程序服务。 若要检索非设备驱动程序服务或服务（不是驱动程序），请调用该方法 GetServices 。 这两种方法一起提供对计算机上的所有服务的访问权限。

• GetServices()

GetDevices(String)

检索指定计算机上的设备驱动程序服务。

public:
 static cli::array <System::ServiceProcess::ServiceController ^> ^ GetDevices(System::String ^ machineName);

public static System.ServiceProcess.ServiceController[] GetDevices (string machineName);

static member GetDevices : string -> System.ServiceProcess.ServiceController[]

Public Shared Function GetDevices (machineName As String) As ServiceController()

参数

machineName

String

要从中检索设备驱动程序服务的计算机。

返回

ServiceController[]

ServiceController 类型的数组，其中每个元素均与指定计算机上的一个设备驱动程序服务关联。

例外

Win32Exception

访问 API 时出错。

ArgumentException

machineName 参数的语法无效。

注解

GetDevices 仅返回来自指定计算机的设备驱动程序服务。 若要检索非设备驱动程序服务或服务（不是驱动程序），请调用该方法 GetServices 。 这两种方法一起提供对计算机上的所有服务的访问权限。
