Esempio

Nell'esempio seguente viene creato un assembly dinamico denominato MyAssembly.exe e salvato nel disco rigido. Dopo aver eseguito l'esempio, è possibile usare il Ildasm.exe (IL Disassembler) per esaminare i metadati dell'assembly.

using namespace System;

   AssemblyBuilder^ myAssemblyBuilder = Thread::GetDomain()->DefineDynamicAssembly( myAssemblyName, AssemblyBuilderAccess::RunAndSave );

   // Create a dynamic module in the assembly.
   ModuleBuilder^ myModuleBuilder = myAssemblyBuilder->DefineDynamicModule( "MyModule", fileName );

   // Create a type in the module.
   TypeBuilder^ myTypeBuilder = myModuleBuilder->DefineType( "MyType" );

   // Create a method called 'Main'.
   MethodBuilder^ myMethodBuilder = myTypeBuilder->DefineMethod( "Main", static_cast<MethodAttributes>(MethodAttributes::Public | MethodAttributes::HideBySig | MethodAttributes::Static), void::typeid, nullptr );

   // Get the Intermediate Language generator for the method.
   ILGenerator^ myILGenerator = myMethodBuilder->GetILGenerator();

   // Use the utility method to generate the IL instructions that print a String* to the console.
   myILGenerator->EmitWriteLine( "Hello World!" );

   // Generate the 'ret' IL instruction.
   myILGenerator->Emit( OpCodes::Ret );

   // End the creation of the type.
   myTypeBuilder->CreateType();

   // Set the method with name 'Main' as the entry point in the assembly.
   myAssemblyBuilder->SetEntryPoint( myMethodBuilder );
   myAssemblyBuilder->Save( fileName );

AssemblyName(String)

Origine:

AssemblyName.cs

Inizializza una nuova istanza della classe AssemblyName con il nome visualizzato specificato.

public:
 AssemblyName(System::String ^ assemblyName);

public AssemblyName (string assemblyName);

new System.Reflection.AssemblyName : string -> System.Reflection.AssemblyName

Public Sub New (assemblyName As String)

Parametri

assemblyName

String

Nome visualizzato dell'assembly, come restituito dalla proprietà FullName.

Eccezioni

ArgumentNullException

assemblyName è null.

ArgumentException

assemblyName è una stringa di lunghezza zero.

FileLoadException

Non è possibile trovare l'assembly a cui viene fatto riferimento oppure non è possibile caricarlo.

Nota: in .NET per le app di Windows Store o la libreria di classi portabili, rilevare invece l'eccezione della classe di base, , IOException.

Esempio

Nell'esempio seguente viene creata un'istanza di AssemblyName da un nome visualizzato. I singoli elementi del nome visualizzato vengono restituiti alla console come proprietà dell'oggetto AssemblyName .

using namespace System;
using namespace System::Reflection;

int main()
{
   // Create an AssemblyName, specifying the display name, and then
   // print the properties.
   AssemblyName^ myAssemblyName = 
      gcnew AssemblyName("Example, Version=1.0.0.2001, Culture=en-US, PublicKeyToken=null");
   Console::WriteLine("Name: {0}", myAssemblyName->Name);
   Console::WriteLine("Version: {0}", myAssemblyName->Version);
   Console::WriteLine("CultureInfo: {0}", myAssemblyName->CultureInfo);
   Console::WriteLine("FullName: {0}", myAssemblyName->FullName);
}

Commenti

L'oggetto assemblyName fornito viene analizzato e i campi appropriati del nuovo AssemblyName vengono inizializzati con valori dal nome visualizzato. Si tratta del modo consigliato per analizzare i nomi visualizzati. Non è consigliabile scrivere il proprio codice per analizzare i nomi visualizzati.
