SecurityPermission(PermissionState)

Inicializa uma nova instância da classe SecurityPermission com permissão irrestrita ou restrita, conforme especificado.

public:
 SecurityPermission(System::Security::Permissions::PermissionState state);

public SecurityPermission (System.Security.Permissions.PermissionState state);

new System.Security.Permissions.SecurityPermission : System.Security.Permissions.PermissionState -> System.Security.Permissions.SecurityPermission

Public Sub New (state As PermissionState)

Parâmetros

state: PermissionState

Um dos valores de PermissionState.

Exceções

ArgumentException

O parâmetro state não é um valor válido de PermissionState.

Comentários

Cria permissões de segurança totalmente restritas (None) ou Unrestricted acesso a todas as permissões de segurança.

SecurityPermission(SecurityPermissionFlag)

Inicializa uma nova instância da classe SecurityPermission com o estado definido inicial especificado dos sinalizadores.

public:
 SecurityPermission(System::Security::Permissions::SecurityPermissionFlag flag);

public SecurityPermission (System.Security.Permissions.SecurityPermissionFlag flag);

new System.Security.Permissions.SecurityPermission : System.Security.Permissions.SecurityPermissionFlag -> System.Security.Permissions.SecurityPermission

Public Sub New (flag As SecurityPermissionFlag)

Parâmetros

flag: SecurityPermissionFlag

O estado inicial da permissão, representado por uma combinação OR bit a bit dos bits de permissão definidos por SecurityPermissionFlag.

Exceções

ArgumentException

O parâmetro flag não é um valor válido de SecurityPermissionFlag.

Exemplos

O exemplo de código a seguir mostra o uso do SecurityPermission construtor para criar instâncias da SecurityPermission classe que são usadas para exigir permissões de segurança. Para obter o exemplo de código completo, consulte o SecurityPermissionAttribute(SecurityAction) construtor.
