Refresh は ServiceController プロパティを既定値に戻します。また、このメソッドは ServicesDependedOn および DependentServices プロパティも null 参照 (Visual Basic では Nothing) に設定します。

使用例

ServiceController クラスを使用して、Telnet サービスの現在のステータスを確認する例を次に示します。サービスが停止している場合、このコードはサービスを開始します。サービスが実行中である場合は、そのサービスを停止します。

Visual Basic

' Toggle the Telnet service - 
' If it is started (running, paused, etc), stop the service.
' If it is stopped, start the service.
Dim sc As New ServiceController("Telnet")
Console.WriteLine("The Telnet service status is currently set
 to {0}", sc.Status)

If sc.Status.Equals(ServiceControllerStatus.Stopped) Or
 sc.Status.Equals(ServiceControllerStatus.StopPending) Then
   ' Start the service if the current status is stopped.
   Console.WriteLine("Starting the Telnet service...")
   sc.Start()
Else
   ' Stop the service if its status is not set to "Stopped".
   Console.WriteLine("Stopping the Telnet service...")
   sc.Stop()
End If

' Refresh and display the current service status.
sc.Refresh()
Console.WriteLine("The Telnet service status is now set to {0}.",
 sc.Status)

// Toggle the Telnet service - 
// If it is started (running, paused, etc), stop the service.
// If it is stopped, start the service.
ServiceController sc = new ServiceController("Telnet");
Console.WriteLine("The Telnet service status is currently set
 to {0}", 
                  sc.Status.ToString());

if  ((sc.Status.Equals(ServiceControllerStatus.Stopped)) ||
     (sc.Status.Equals(ServiceControllerStatus.StopPending)))
{
   // Start the service if the current status is stopped.

   Console.WriteLine("Starting the Telnet service...");
   sc.Start();
}  
else
{
   // Stop the service if its status is not set to "Stopped".

   Console.WriteLine("Stopping the Telnet service...");
   sc.Stop();
}  

// Refresh and display the current service status.
sc.Refresh();
Console.WriteLine("The Telnet service status is now set to
 {0}.", 
                   sc.Status.ToString());

C++

// Toggle the Telnet service - 
// If it is started (running, paused, etc), stop the service.
// If it is stopped, start the service.
ServiceController^ sc = gcnew ServiceController(  "Telnet" );
if ( sc )
{
   Console::WriteLine(  "The Telnet service status is currently set
 to {0}", sc->Status );
   if ( (sc->Status == (ServiceControllerStatus::Stopped) )
 || (sc->Status == (ServiceControllerStatus::StopPending) ) )
   {
      // Start the service if the current status is stopped.
      Console::WriteLine(  "Starting the Telnet service..." );
      sc->Start();
   }
   else
   {
      // Stop the service if its status is not set to "Stopped".
      Console::WriteLine(  "Stopping the Telnet service..." );
      sc->Stop();
   }

   // Refresh and display the current service status.
   sc->Refresh();
   Console::WriteLine(  "The Telnet service status is now set
 to {0}.", sc->Status );

// Toggle the Telnet service - 
// If it is started (running, paused, etc), stop the service.
// If it is stopped, start the service.
ServiceController sc = new ServiceController("Telnet");
Console.WriteLine("The Telnet service status is currently set
 to {0}",
    sc.get_Status().ToString());

if (sc.get_Status().Equals(ServiceControllerStatus.Stopped) ||
 
    sc.get_Status().Equals(ServiceControllerStatus.StopPending)) {
    // Start the service if the current status is stopped.
    Console.WriteLine("Starting the Telnet service...");
    sc.Start();
}
else {
    // Stop the service if its status is not set to "Stopped".
    Console.WriteLine("Stopping the Telnet service...");
    sc.Stop();
}
// Refresh and display the current service status.
sc.Refresh();
Console.WriteLine("The Telnet service status is now set to
 {0}.", 
    sc.get_Status().ToString());
