Parametri

Esempio

Nell'esempio di codice seguente viene associato un ResolveNameEventHandler oggetto all'evento ResolveName di un oggetto specificato IDesignerSerializationManager.

public:
   void LinkResolveNameEvent( IDesignerSerializationManager^ serializationManager )
   {
      // Registers an event handler for the ResolveName event.
      serializationManager->ResolveName +=
         gcnew ResolveNameEventHandler( this, &Form1::OnResolveName );
   }

private:
   void OnResolveName( Object^ sender, ResolveNameEventArgs^ e )
   {
      // Displays ResolveName event information on the console.
      Console::WriteLine( "Name of the name to resolve: " + e->Name );
      Console::WriteLine( "ToString output of the Object that no name was resolved for: " +
         e->Value );
   }

public void LinkResolveNameEvent(
        IDesignerSerializationManager serializationManager)
{
    // Registers an event handler for the ResolveName event.
    serializationManager.ResolveName += 
        new ResolveNameEventHandler(this.OnResolveName);
}

private void OnResolveName(object sender, ResolveNameEventArgs e)
{                        
    // Displays ResolveName event information on the console. 
    Console.WriteLine("Name of the name to resolve: "+e.Name);
    Console.WriteLine("ToString output of the object that no name was resolved for: "+e.Value.ToString());            
}

Public Sub LinkResolveNameEvent(ByVal serializationManager As IDesignerSerializationManager)
    ' Registers an event handler for the resolve name event.
    AddHandler serializationManager.ResolveName, AddressOf Me.OnResolveName
End Sub

Private Sub OnResolveName(ByVal sender As Object, ByVal e As ResolveNameEventArgs)
    ' Displays ResolveName event information on the Console.
    Console.WriteLine(("Name of the name to resolve: " + e.Name))
    Console.WriteLine(("ToString output of the object that no name was resolved for: " + e.Value.ToString()))
End Sub

Commenti

Questo delegato viene utilizzato da IDesignerSerializationManager per risolvere i nomi degli oggetti durante la serializzazione e la deserializzazione.

Quando si crea un delegato ResolveNameEventHandler, si identifica il metodo che gestirà l'evento. Per associare l'evento al gestore eventi in uso, aggiungere all'evento un'istanza del delegato. Il gestore eventi viene chiamato ogni volta che si verifica l'evento, a meno che non venga rimosso il delegato. Per altre informazioni sui delegati del gestore eventi, vedere Gestione e generazione di eventi.
