Public Sub AddConnectAccess (originScheme As String, connectAccess As CodeConnectAccess)

Parametri

originScheme

String

Oggetto String contenente lo schema con cui trovare una corrispondenza sulla base dello schema del codice.

connectAccess

CodeConnectAccess

Oggetto CodeConnectAccess che specifica lo schema e la porta utilizzabili dal codice per la connessione al server di origine.

Eccezioni

ArgumentNullException

originScheme è null.

ArgumentOutOfRangeException

originScheme contiene caratteri non consentiti negli schemi.

-oppure-

originScheme = AbsentOriginScheme e connectAccess specificano OriginScheme come schema.

Esempio

Nell'esempio di codice seguente viene illustrata la creazione e l'aggiunta CodeConnectAccess di oggetti a un NetCodeGroupoggetto .

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();
    // Create an object that represents access to the FTP scheme and 
    // default port.
    CodeConnectAccess^ CodeAccessFtp = 
        gcnew CodeConnectAccess(Uri::UriSchemeFtp, 
        CodeConnectAccess::DefaultPort);
    // Create an object that represents access to the HTTPS scheme 
    // and default port.
    CodeConnectAccess^ CodeAccessHttps = 
        gcnew CodeConnectAccess(Uri::UriSchemeHttps, 
        CodeConnectAccess::DefaultPort);
    // Create an object that represents access to the origin 
    // scheme and port.
    CodeConnectAccess^ CodeAccessOrigin = 
        CodeConnectAccess::CreateOriginSchemeAccess
        (CodeConnectAccess::OriginPort);
    // Add connection access objects to the NetCodeGroup object.
    codeGroup->AddConnectAccess(Uri::UriSchemeHttp, CodeAccessFtp);
    codeGroup->AddConnectAccess(Uri::UriSchemeHttp, CodeAccessHttps);
    codeGroup->AddConnectAccess(Uri::UriSchemeHttp, CodeAccessOrigin);
    // Provide name and description information for caspol.exe tool.
    codeGroup->Name = "ContosoHttpCodeGroup";
    codeGroup->Description = "Code originating from contoso.com can" +
        " connect back using the FTP or HTTPS.";
    // Add the code group to the User policy's root node.
    level->RootCodeGroup->AddChild(codeGroup);
    // Save the changes to the policy level.
    System::Security::SecurityManager::SavePolicy();
}

public static void SetNetCodeGroupAccess()
{
    const string userPolicyLevel = "User";
    // Locate the User policy level.
    PolicyLevel level = null;
    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 new ApplicationException("Could not find User policy level.");

    IMembershipCondition membership =
        new UrlMembershipCondition(@"http://www.contoso.com/*");
    NetCodeGroup codeGroup = new NetCodeGroup(membership);
    // Delete default settings.
    codeGroup.ResetConnectAccess();
    // Create an object that represents access to the FTP scheme and default port.
    CodeConnectAccess a1 = new CodeConnectAccess(Uri.UriSchemeFtp, CodeConnectAccess.DefaultPort);
    // Create an object that represents access to the HTTPS scheme and default port.
    CodeConnectAccess a2 = new CodeConnectAccess(Uri.UriSchemeHttps, CodeConnectAccess.DefaultPort);
    // Create an object that represents access to the origin scheme and port.
    CodeConnectAccess a3 = CodeConnectAccess.CreateOriginSchemeAccess(CodeConnectAccess.OriginPort);
    // Add connection access objects to the NetCodeGroup object.
    codeGroup.AddConnectAccess(Uri.UriSchemeHttp, a1);
    codeGroup.AddConnectAccess(Uri.UriSchemeHttp, a2);
    codeGroup.AddConnectAccess(Uri.UriSchemeHttp, a3);
    // Provide name and description information for caspol.exe tool.
    codeGroup.Name = "ContosoHttpCodeGroup";
    codeGroup.Description = "Code originating from contoso.com can connect back using the FTP or HTTPS.";
    // Add the code group to the User policy's root node.
    level.RootCodeGroup.AddChild(codeGroup);
    // Save the changes to the policy level.
    System.Security.SecurityManager.SavePolicy();
}

Commenti

È possibile aggiungere più CodeConnectAccess oggetti per lo stesso origin schemeoggetto . Se un oggetto origin scheme ha già uno o più oggetti associati CodeConnectAccess , specificando null per connectAccess non ha alcun effetto. Se lo schema di origine non dispone di oggetti associati CodeConnectAccess , specificando null per connectAccess impedire il codice con uno schema di origine corrispondente originScheme all'accesso al server di origine.
