GacInstalled Classe

Definição

Namespace:

System.Security.Policy

Assembly:

System.Security.Permissions.dll

Assembly:

mscorlib.dll

Cuidado

Code Access Security is not supported or honored by the runtime.

Confirma que um assembly de código é originado no GAC (cache de assembly global) como evidência para avaliação de política. Essa classe não pode ser herdada.

Comentários

Cuidado

O CAS (Code Access Security) foi preterido em todas as versões do .NET Framework e do .NET. As versões recentes do .NET não respeitam as anotações CAS e produzem erros se AS APIs relacionadas ao CAS forem usadas. Os desenvolvedores devem buscar meios alternativos de realizar tarefas de segurança.

A presença de GacInstalled evidências produz um GacIdentityPermission no conjunto de concessões. Se houver um Demand for, o GacIdentityPermission que corresponde à GacInstalled evidência será comparado com a permissão GacIdentityPermissionexigida.

Construtores

GacInstalled()

Inicializa uma nova instância da classe GacInstalled.

Métodos

Clone()	Cria um novo objeto que é uma cópia da instância atual.
Clone()	Cria um novo objeto que é uma cópia completa da instância atual. (Herdado de EvidenceBase)
Copy()	Cria uma cópia equivalente do objeto atual.
CreateIdentityPermission(Evidence)	Cria uma nova permissão de identidade que corresponde ao objeto atual.
Equals(Object)	indica se o objeto especificado é igual ao objeto atual.
GetHashCode()	Retorna um código hash para o objeto atual.
GetType()	Obtém o Type da instância atual. (Herdado de Object)
MemberwiseClone()	Cria uma cópia superficial do Object atual. (Herdado de Object)
ToString()	Retorna uma representação de cadeia de caracteres do objeto atual.
