ServiceController.GetDevices Method

Retrieves the device driver services on the local computer.

Namespace:  System.ServiceProcess
Assembly:  System.ServiceProcess (in System.ServiceProcess.dll)
'Declaration
Public Shared Function GetDevices As ServiceController()

Return Value

Type: System.ServiceProcess.ServiceController()
An array of type ServiceController in which each element is associated with a device driver service on the local computer.
ExceptionCondition
Win32Exception

An error occurred when accessing a system API.

GetDevices returns only the device driver services from the local computer. To retrieve the non-device driver services or services that are not drivers, call the GetServices method. Together, the two methods provide access to all the services on a computer.

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()
         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)
