Przykłady

Poniższy przykład kodu tworzy NetCodeGroup obiekt i dodaje go do poziomu zasad użytkownika.

static void SetNetCodeGroupAccess()
{
    String^ userPolicyLevel = "User";
    // Locate the User policy level.
    PolicyLevel^ level = nullptr;
    System::Collections::IEnumerator^ ph = 
        System::Security::SecurityManager::PolicyHierarchy();
    while(ph->MoveNext())
    {
        level = (PolicyLevel^)ph->Current;
        if (level->Label == userPolicyLevel)
        {
            break;       
        }

Uwagi

Ta klasa jest używana w połączeniu z klasą NetCodeGroup w celu kontrolowania sposobu, w jaki wykonywanie kodu może nawiązać połączenie z witryną, z którego została pobrana. Te klasy zapewniają programową kontrolę WebPermission nad udzielonym wykonywaniem kodu, który kontroluje schematy i porty, których kod może używać do uzyskiwania dostępu do jego lokacji źródłowej. Można określić pary schematów i portów, które są dozwolone na podstawie schematu w adresie URL, z którego pochodzi kod.

Aby utworzyć CodeConnectAccess obiekt na podstawie schematu pochodzenia kodu, użyj CreateOriginSchemeAccess metody .

Aby utworzyć CodeConnectAccess obiekt, który może używać dowolnego schematu, ale jest ograniczony przez port, użyj CreateAnySchemeAccess metody .
