Beispiele

Im folgenden Beispiel wird eine dynamische Assembly mit dem Namen EmittedManifestResourceAssembly.exegeneriert und gespeichert, die eine eingebettete nicht verwaltete Ressource enthält. Das Beispiel erstellt die Assembly, die aus einem Modul besteht, und öffnet einen Speicherdatenstrom, der die nicht verwaltete Ressource enthält. Der Code ruft dann die DefineManifestResource -Methode auf, um die Ressource zu definieren.

Das Beispiel definiert einen Typ im dynamischen Modul mit einer Main -Methode und generiert MSIL für den Methodentext. Nachdem der Text für die Main -Methode generiert und der Typ erstellt wurde, schreibt das Codebeispiel fünf Bytes in den Stream, der der Manifestressource zugeordnet ist. Wenn die Assembly gespeichert wird, wird ihr die Ressource angefügt.

Nachdem Sie das Beispiel ausgeführt haben, können Sie die ausgegebene Assembly ausführen. Der Code in der Methode der ausgegebenen Assembly Main liest die eingebettete Manifestressource und gibt die Bytewerte an die Konsole aus. Sie können den Ildasm.exe (IL Disassembler) verwenden, um die Informationen im Assemblymanifest anzuzeigen.

Hinweise

Ressourcen, die im Assemblymanifest aufgezeichnet werden, können verwaltete Ressourcen oder Manifestressourcen-BLOBs sein, und jede dieser Ressourcen kann entweder durch Verknüpfen oder durch Einbetten in die Assembly eingeschlossen werden. Alle vier Szenarien werden für dynamische Assemblys unterstützt.

• Mit dieser Methode können Sie ein Manifestressourcenblob in eine dynamische Assembly einbetten.

• Um eine verwaltete Ressource in das Manifestmodul einer dynamischen Assembly oder in ein Satellitenmodul einzubetten, verwenden Sie die ModuleBuilder.DefineResource -Methode, um einen Ressourcenschreiber abzurufen, und verwenden Sie die ResourceWriter.AddResource -Methode, um die Ressource hinzuzufügen.

• Um eine verwaltete Ressource mit einer dynamischen Assembly zu verknüpfen, verwenden Sie die AssemblyBuilder.DefineResource -Methode, um einen Ressourcenschreiber abzurufen, und verwenden Sie die ResourceWriter.AddResource -Methode, um die verknüpfte Ressource hinzuzufügen.

• Um ein Manifestressource-BLOB mit einer dynamischen Assembly zu verknüpfen, verwenden Sie die AssemblyBuilder.AddResourceFile -Methode, um die verknüpfte Ressource hinzuzufügen.

Darüber hinaus kann eine einzelne Win32-Ressource mit der AssemblyBuilder.DefineUnmanagedResource -Methode oder - ModuleBuilder.DefineUnmanagedResource Methode an eine Assembly angefügt werden. Diese Ressource wird nicht im Assemblymanifest angezeigt.
