使用例

ServiceController クラスを使用して、Messenger サービスに依存するサービスのセットを表示する例を次に示します。

Visual Basic

Dim sc As New ServiceController("Messenger")
Dim scServices As ServiceController() = sc.ServicesDependedOn

' Display the services that the Messenger service is dependent on.
If scServices.Length = 0 Then
   Console.WriteLine("{0} service is not dependent on any other
 services.", sc.ServiceName)
Else
   Console.WriteLine("{0} service is dependent on the following:",
 sc.ServiceName)
   
   Dim scTemp As ServiceController
   For Each scTemp In  scServices
      Console.WriteLine(" {0}", scTemp.DisplayName)
   Next scTemp
End If

ServiceController sc = new ServiceController("Messenger");
ServiceController[] scServices= sc.ServicesDependedOn;

// Display the services that the Messenger service is dependent on.
if (scServices.Length == 0)
{
   Console.WriteLine("{0} service is not dependent on any other services.",
 
                      sc.ServiceName);
}
else 
{
   Console.WriteLine("{0} service is dependent on the following:",
                      sc.ServiceName);

   foreach (ServiceController scTemp in scServices)
   {
      Console.WriteLine(" {0}", scTemp.DisplayName);
   }
}

C++

ServiceController^ sc = gcnew ServiceController(  "Messenger" );
array<ServiceController^>^scServices = nullptr;
if ( sc )
{
   scServices = sc->ServicesDependedOn;
}

if ( sc && scServices )
{
   // Display the services that the Messenger service is dependent on.
   if ( scServices->Length == 0 )
   {
      Console::WriteLine(  "{0} service is not dependent on any other services.",
 sc->ServiceName );
   }
   else
   {
      Console::WriteLine(  "{0} service is dependent on the following:",
 sc->ServiceName );
      for each (ServiceController^ scTemp in
 scServices)
      {
         Console::WriteLine(" {0}", scTemp->DisplayName);
      }
   }
}

ServiceController sc = new ServiceController("Messenger");
ServiceController scServices[] = sc.get_ServicesDependedOn();
// Display the services that the Messenger service is dependent on.
if (scServices.length == 0) {
    Console.WriteLine("{0} service is not dependent on any other "
        + "services.", sc.get_ServiceName());
}
else {
    Console.WriteLine("{0} service is dependent on the following:",
        sc.get_ServiceName());
    ServiceController scTemp = null;
    for (int iCtr = 0; iCtr < scServices.get_Length();
 iCtr++) {
        scTemp = scServices[iCtr];
        Console.WriteLine(" {0}", scTemp.get_DisplayName());
    }
}
