Exemplos

O exemplo a seguir demonstra o uso de GacIdentityPermissionAttribute.

// To run this sample you must create a strong-name key named snkey.snk 
// using the Strong Name tool (sn.exe).  Both the library assembly and the 
// application assembly that calls it must be signed with that key.  
// To run successfully, the application assembly must be in the global 
// assembly cache.
// This console application can be created using the following code.

//#using <mscorlib.dll>
//#using <ClassLibrary1.dll>
//using namespace System;
//using namespace System::Security;

Comentários

Essa classe é usada para garantir que os chamadores sejam registrados no GAC (cache de assembly global).

O escopo da declaração permitida depende do SecurityAction valor usado.

As informações de segurança declaradas por um atributo de segurança são armazenadas nos metadados do destino do atributo e são acessadas pelo sistema em tempo de execução. Os atributos de segurança são usados apenas para segurança declarativa. Para segurança imperativa, use a classe de permissão correspondente, GacIdentityPermission.

Para obter mais informações sobre como usar atributos, consulte Atributos.
