Esempi

Nell'esempio seguente viene eseguito un tentativo di caricamento di un tipo non esistente dall'assembly mscorlib.The following example attempts to load a non-existent type from the mscorlib assembly. Viene rilevata l'eccezione risultante e TypeName vengono Message visualizzati i valori e.The resulting exception is caught, and the TypeName and Message values are displayed. Per eseguire questo esempio di codice, 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 nomi degli assembly.For information about how to obtain the fully qualified assembly name, see Assembly Names.

// Load the mscorlib assembly and get a reference to it.
// You must supply the fully qualified assembly name for mscorlib.dll here.
Assembly^ myAssembly = Assembly::Load( "Assembly text name, Version, Culture, PublicKeyToken" );

   Type^ myType = myAssembly->GetType( "System.NonExistentType", true );
}
catch ( TypeLoadException^ e )

   // Display the name of the Type that was not found.
