En el ejemplo siguiente se crea una instancia de WebPermission y se conceden derechos de acceso a direcciones URL específicas.

// Create a WebPermission instance.
WebPermission^ myWebPermission1 = gcnew WebPermission( PermissionState::None );

// Allow access to the first set of URL's.
myWebPermission1->AddPermission( NetworkAccess::Connect, "http://www.microsoft.com/default.htm" );
myWebPermission1->AddPermission( NetworkAccess::Connect, "http://www.msn.com" );

// Check whether all callers higher in the call stack have been granted the permissionor not.
myWebPermission1->Demand();

// Create a WebPermission instance.  
WebPermission myWebPermission1 = new WebPermission(PermissionState.None);

// Allow access to the first set of URL's.
myWebPermission1.AddPermission(NetworkAccess.Connect,"http://www.microsoft.com/default.htm");
myWebPermission1.AddPermission(NetworkAccess.Connect,"http://www.msn.com");

// Check whether all callers higher in the call stack have been granted the permissionor not.
myWebPermission1.Demand();

' Create a WebPermission instance.  
Dim myWebPermission1 As New WebPermission(PermissionState.None)

' Allow access to the first set of URL's.
myWebPermission1.AddPermission(NetworkAccess.Connect, "http://www.microsoft.com/default.htm")

Comentarios

El valor del state parámetro es PermissionState.None o PermissionState.Unrestricted, respectivamente, que produce acceso totalmente restringido o totalmente sin restricciones a todas las variables de seguridad. Si especifica PermissionState.None, puede conceder acceso a URI individuales mediante AddPermission.
