ServiceController.GetDevices Method ()

Retrieves the device driver services on the local computer.

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

public static ServiceController[] GetDevices ()
public static ServiceController[] GetDevices ()
public static function GetDevices () : ServiceController[]
Not applicable.

Return Value

An array of type ServiceController in which each element is associated with a device driver service on the local computer.

Exception typeCondition

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.

ServiceController[] scDevices;
scDevices = ServiceController.GetDevices();

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:");

foreach (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) != 0)
   {
      numAdapter++;
   } 
   if ((scTemp.ServiceType & ServiceType.FileSystemDriver) != 0)
   {
      numFileSystem++;
   }  
   if ((scTemp.ServiceType & ServiceType.KernelDriver) != 0)
   {
      numKernel++;
   } 
   if ((scTemp.ServiceType & ServiceType.RecognizerDriver) != 0)
   {
      numRecognizer++;
   }

}

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);

int numFileSystem = 0;

// Display the list of device driver services.
Console.WriteLine("Device driver services on the local computer:");
ServiceController scTemp = null;
for (int iCtr = 0; iCtr < scDevices.get_Length(); iCtr++) {
    // Display the status and the service name, for example,
    // [Running] PCI Bus Driver
    // Type = KernelDriver
    scTemp = scDevices[iCtr];

    Console.WriteLine(" [{0}] {1}", scTemp.get_Status(), 
        scTemp.get_DisplayName());

        scTemp.get_ServiceType());
    // Update counters using the service type bit flags.
    if (System.Convert.ToInt32(scTemp.get_ServiceType() &
        ServiceType.Adapter) != 0) {
        numAdapter++;
    }
    if ((System.Convert.ToInt32(scTemp.get_ServiceType() & 
        ServiceType.FileSystemDriver)) != 0) {
        numFileSystem++;
    }
    if (System.Convert.ToInt32((scTemp.get_ServiceType() & 
        ServiceType.KernelDriver)) != 0) {
        numKernel++;

    if (System.Convert.ToInt32((scTemp.get_ServiceType() & 
        ServiceType.RecognizerDriver)) != 0) {
