Exemplos

O exemplo de código a seguir ilustra o uso do HostProtectionAttribute atributo com a ExternalThreading propriedade . Este exemplo faz parte de um exemplo maior fornecido para a HostProtectionAttribute classe .

// Use the enumeration flags to indicate that this method exposes synchronization 
//  and external threading.

[HostProtection(Synchronization=true,ExternalThreading=true)]
static void StartThread()
{
   Thread^ t = gcnew Thread( gcnew ThreadStart( WatchFileEvents ) );
   
   // Start the new thread.  On a uniprocessor, the thread is not given 
   // any processor time until the main thread yields the processor.  
   t->Start();
   
   // Give the new thread a chance to execute.
   Thread::Sleep( 1000 );
}

// Use the enumeration flags to indicate that this method exposes 
// synchronization and external threading.
[HostProtectionAttribute(Synchronization=true, ExternalThreading=true)]
private static void StartThread()
{
    Thread t = new Thread(new ThreadStart(WatchFileEvents));
    
    // Start the new thread. On a uniprocessor, the thread is not given
    // any processor time until the main thread yields the processor.
    t.Start();
    
    // Give the new thread a chance to execute.
    Thread.Sleep(1000);
}

' Use the enumeration flags to indicate that this method exposes  
' synchronization and external threading.
<HostProtectionAttribute(Synchronization := True, _
    ExternalThreading := True)> _
Private Shared Sub StartThread()
    Dim t As New Thread(New ThreadStart(AddressOf WatchFileEvents))

    ' Start the new thread. On a uniprocessor, the thread is not given 
    ' any processor time until the main thread yields the processor.  
    t.Start()

    ' Give the new thread a chance to execute.
    Thread.Sleep(1000)
End Sub

Comentários

O código que expõe threading externo cria ou manipula threads que não sejam os próprios, o que pode ser prejudicial ao host.
