Примеры

В следующем образце показано AssemblyLoad событий.The following sample demonstrates the AssemblyLoad event.

Для этого примера кода для запуска необходимо указать полное имя сборки.For this code example to run, you must provide the fully qualified assembly name. Сведения о том, как получить полное имя сборки, см. в разделе имена сборок.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.
   currentDomain->CreateInstance( "System.Windows.Forms, Version, Culture, PublicKeyToken", "System.Windows.Forms.TextBox" );
   
   // Loads System, System::Drawing, System::Windows::Forms
   PrintLoadedAssemblies( currentDomain );

Комментарии

AssemblyLoadEventHandler Делегат для этого события определяет, какая сборка была загружена.The AssemblyLoadEventHandler delegate for this event indicates what assembly was loaded.

Чтобы зарегистрировать обработчик событий для этого события, необходимо иметь необходимые разрешения, или SecurityException возникает исключение.To register an event handler for this event, you must have the required permissions, or a SecurityException is thrown.

Дополнительные сведения об обработке событий см. в разделе обработка и вызов событий.For more information about handling events, see Handling and Raising Events.
