ServiceType Enumeration

Represents the type of the service.

This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.

Namespace:  System.ServiceProcess
Assembly:  System.ServiceProcess (in System.ServiceProcess.dll)

<FlagsAttribute> _
Public Enumeration ServiceType

Member nameDescription
AdapterA service for a hardware device that requires its own driver.
FileSystemDriverA file system driver, which is also a Kernel device driver.
InteractiveProcessA service that can communicate with the desktop.
KernelDriverA Kernel device driver such as a hard disk or other low-level hardware device driver.
RecognizerDriverA file system driver used during startup to determine the file systems present on the system.
Win32OwnProcessA 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.
Win32ShareProcessA Win32 service that can share a process with other Win32 services.

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. For code samples on remoting, see [<topic://cpconRemotingExamples>].

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

         Dim scDevices() As ServiceController
         scDevices = ServiceController.GetDevices()

         Dim numAdapter As Integer
         Dim numFileSystem As Integer
         Dim numKernel As Integer
         Dim numRecognizer As Integer

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

         Dim scTemp As ServiceController
         For Each 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 And ServiceType.Adapter) <> 0 Then
               numAdapter = numAdapter + 1
            End If
            If (scTemp.ServiceType And ServiceType.FileSystemDriver) <> 0 Then
               numFileSystem = numFileSystem + 1
            End If
            If (scTemp.ServiceType And ServiceType.KernelDriver) <> 0 Then
               numKernel = numKernel + 1
            End If
            If (scTemp.ServiceType And ServiceType.RecognizerDriver) <> 0 Then
               numRecognizer = numRecognizer + 1
            End If

         Next scTemp

         Console.WriteLine("Total of {0} device driver services", scDevices.Length)
         Console.WriteLine("  {0} are adapter drivers", numAdapter)
         Console.WriteLine("  {0} are file system drivers", numFileSystem)
         Console.WriteLine("  {0} are kernel drivers", numKernel)
         Console.WriteLine("  {0} are file system recognizer drivers", numRecognizer)
