Aşağıdaki örnekte, adlı dinamik türe MyDynamicClassbayrağıyla bir SecurityPermissionFlag.ControlEvidence güvenlik talebi eklemek için SecurityPermission yönteminin AddDeclarativeSecurity kullanımı EmittedExample.dll adlı bir derlemede gösterilmiştir. Örnek konsol çıkışı üretmez; çalıştırdıktan sonra EmittedExample.dll incelemek için Ildasm.exe (IL Disassembler) kullanabilirsiniz. bildirim MyDynamicClassiznini .class public auto ansi görmek için içinde deyimini açın.
