ServiceType Enum

Definition

Namespace:

System.ServiceProcess

Assembly:

System.ServiceProcess.ServiceController.dll

Package:

System.ServiceProcess.ServiceController v10.0.0-preview.1.25080.5

Source:

ServiceType.cs

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.

C#

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);

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.
