AppDomain::AssemblyLoad Event

Occurs when an assembly is loaded.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

virtual   event AssemblyLoadEventHandler^ AssemblyLoad {
	void add (AssemblyLoadEventHandler^ value);
	void remove (AssemblyLoadEventHandler^ value);



The AssemblyLoadEventHandler delegate for this event indicates what assembly was loaded.

To register an event handler for this event, you must have the required permissions, or a SecurityException is thrown.

For more information about handling events, see Consuming Events.

The following example demonstrates the AssemblyLoad event.

For this code example to run, you must provide the fully qualified assembly name. For information about how to obtain the fully qualified assembly name, see Assembly Names.

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


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 );


int main()
   AppDomain^ currentDomain = AppDomain::CurrentDomain;
   currentDomain->AssemblyLoad += gcnew AssemblyLoadEventHandler( Test::MyAssemblyLoadEventHandler );
   PrintLoadedAssemblies( currentDomain );

   // Lists mscorlib and this assembly 
   // 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 );

   // Lists all five assemblies
