Beispiele

Im folgenden Codebeispiel wird das Erstellen eines NetCodeGroup und das Hinzufügen von CodeConnectAccess Objekten für Code veranschaulicht, der mithilfe des HTTP-Schemas heruntergeladen wurde.

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;       
        }
    }
    if (level->Label != userPolicyLevel)
        throw gcnew ApplicationException("Could not find User policy level.");

    IMembershipCondition^ membership =
        gcnew UrlMembershipCondition("http://www.contoso.com/*");
    NetCodeGroup^ codeGroup = gcnew NetCodeGroup(membership);
    // Delete default settings.
    codeGroup->ResetConnectAccess();

    CodeConnectAccess a3 = CodeConnectAccess.CreateOriginSchemeAccess(CodeConnectAccess.OriginPort);
    // Add connection access objects to the NetCodeGroup object.
    codeGroup.AddConnectAccess(Uri.UriSchemeHttp, a1);

Hinweise

Wenn eine NetCodeGroup erstellt wird, enthält sie die in der folgenden Tabelle gezeigten Standardzugriffsregeln für den Verbindungszugriff.

Schema	Regel
file	Es ist kein Verbindungszugriff auf den Ursprungsserver zulässig.
http	HTTP- und HTTPS-Zugriff ist über den Ursprungsport zulässig.
https	DER HTTPS-Zugriff ist über den Ursprungsport zulässig.
