名前空間: System.ServiceProcess
アセンブリ: System.ServiceProcess (system.serviceprocess.dll 内)
構文

Visual Basic (宣言)

Public ReadOnly Property
 ServiceType As ServiceType

Visual Basic (使用法)

Dim instance As ServiceController
Dim value As ServiceType

value = instance.ServiceType

C#

public ServiceType ServiceType { get; }

C++

public:
property ServiceType ServiceType {
    ServiceType get ();
}

J#

/** @property */
public ServiceType get_ServiceType ()

JScript

public function get ServiceType
 () : ServiceType

プロパティ値
ネットワーク サービスの種類を示すために使用する ServiceType 値の 1 つ。

例外

例外の種類	条件
Win32Exception	システム API へのアクセス中にエラーが発生しました。

解説

サービスの種類は、サービスがシステムでどのように使用されるのかを示します。ServiceType プロパティの値はフラグのセットを表し、ビットごとの OR 演算子を使用して組み合わせることができます。

使用例

ServiceController クラスを使用して、ローカル コンピュータのデバイス ドライバ サービスを表示する例を次に示します。

Visual Basic

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",
