Ejemplos

En el ejemplo siguiente se usa la AcceptList propiedad para devolver una lista de puntos de conexión a los que se conceden privilegios de aceptación.

// Creates a SocketPermission restricting access to and from all URIs.
SocketPermission^ mySocketPermission1 = gcnew SocketPermission( PermissionState::None );

// The socket to which this permission will apply will allow connections from www.contoso.com.
mySocketPermission1->AddPermission( NetworkAccess::Accept, TransportType::Tcp,  "www.contoso.com", 11000 );

// Creates a SocketPermission which will allow the target Socket to connect with www.southridgevideo.com.
SocketPermission^ mySocketPermission2 = gcnew SocketPermission( NetworkAccess::Connect,TransportType::Tcp, "www.southridgevideo.com",11002 );

// Creates a SocketPermission from the union of two SocketPermissions.
SocketPermission^ mySocketPermissionUnion =
   (SocketPermission^)( mySocketPermission1->Union( mySocketPermission2 ) );

// Checks to see if the union was successfully created by using the IsSubsetOf method.
if ( mySocketPermission1->IsSubsetOf( mySocketPermissionUnion ) &&
   mySocketPermission2->IsSubsetOf( mySocketPermissionUnion ) )
