Exemplos

O exemplo a seguir demonstra o uso do método para adicionar uma demanda de AddDeclarativeSecurity segurança para SecurityPermission com o SecurityPermissionFlag.ControlEvidence sinalizador a um tipo dinâmico chamado MyDynamicClass, em um assembly chamado EmittedExample.dll. O exemplo não produz nenhuma saída de console; depois de executá-lo, você pode usar Ildasm.exe (IL Disassembler) para examinar EmittedExample.dll. Em MyDynamicClass, abra a .class public auto ansi instrução para ver a permissão declarativa.
