Esempi

Nell'esempio seguente viene illustrato il AssemblyLoad evento.The following sample demonstrates the AssemblyLoad event.

Per questo esempio di codice per l'esecuzione, è necessario specificare il nome completo dell'assembly.For this code example to run, you must provide the fully qualified assembly name. Per informazioni su come ottenere il nome completo dell'assembly, vedere i nomi degli Assembly.For information about how to obtain the fully qualified assembly name, see Assembly Names.

using namespace System;
using namespace System::Reflection;
ref class Test
{
public:
   static void MyAssemblyLoadEventHandler( Object^ sender, AssemblyLoadEventArgs^ args )
   {
      Console::WriteLine( "ASSEMBLY LOADED: {0}", args->LoadedAssembly->FullName );
      Console::WriteLine();
   }

};

void PrintLoadedAssemblies( AppDomain^ domain )
{
   Console::WriteLine( "LOADED ASSEMBLIES:" );
   System::Collections::IEnumerator^ myEnum = domain->GetAssemblies()->GetEnumerator();
   while ( myEnum->MoveNext() )
   {
      Assembly^ a = safe_cast<Assembly^>(myEnum->Current);
      Console::WriteLine( a->FullName );
   }

   Console::WriteLine();
}

   // You must supply a valid fully qualified assembly name here.

Commenti

Il AssemblyLoadEventHandler delegato per questo evento indica quali assembly è stato caricato.The AssemblyLoadEventHandler delegate for this event indicates what assembly was loaded.

Per registrare un gestore eventi per questo evento, è necessario disporre delle autorizzazioni necessarie, o un SecurityException viene generata un'eccezione.To register an event handler for this event, you must have the required permissions, or a SecurityException is thrown.

Per ulteriori informazioni sulla gestione degli eventi, consultare gestione e generazione di eventi.For more information about handling events, see Handling and Raising Events.

Sicurezza

SecurityCriticalAttribute
richiede l'attendibilità totale per il chiamante immediato.Requires full trust for the immediate caller. Questo membro non può essere utilizzato da codice parzialmente attendibile o trasparente.This member cannot be used by partially trusted or transparent code.
