Definition

Namespace:

System.ServiceProcess

Assembly:

System.ServiceProcess.ServiceController.dll

Package:

System.ServiceProcess.ServiceController v9.0.0-rc.2.24473.5

Source:

Represents the type of the service.

This enumeration supports a bitwise combination of its member values.

Fields

Name	Value	Description
KernelDriver	1	A Kernel device driver such as a hard disk or other low-level hardware device driver.
FileSystemDriver	2	A file system driver, which is also a Kernel device driver.
Adapter	4	A service for a hardware device that requires its own driver.
RecognizerDriver	8	A file system driver used during startup to determine the file systems present on the system.
Win32OwnProcess	16	A Win32 program that can be started by the Service Controller and that obeys the service control protocol. This type of Win32 service runs in a process by itself.
Win32ShareProcess	32	A Win32 service that can share a process with other Win32 services.
InteractiveProcess	256	A service that can communicate with the desktop.

Examples

The following example uses the ServiceController class to display the device driver services on the local computer.

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++;
      }
      if ( (scTemp->ServiceType & ServiceType::FileSystemDriver) != (ServiceType)0 )
      {
         numFileSystem++;
      }
      if ( (scTemp->ServiceType & ServiceType::KernelDriver) != (ServiceType)0 )
      {
         numKernel++;
      }
      if ( (scTemp->ServiceType & ServiceType::RecognizerDriver) != (ServiceType)0 )
      {

                     scTemp.Status, scTemp.DisplayName);
   Console.WriteLine("           Type = {0}", scTemp.ServiceType);

   // Update counters using the service type bit flags.

Remarks

The service type indicates how the service is used by the system. The ServiceController that passes commands to the service stores a value for the service type.

The value of a ServiceType instance represents a set of flags combined using the bitwise OR operator.

The creation of interactive services is not supported. To workaround this, you can create a non-interactive service and a separate control GUI application that communicates with the service using sockets or remoting.
