PassportIdentity-Klasse
Stellt eine Klasse bereit, die von PassportAuthenticationModule verwendet wird. Sie stellt ein Verfahren bereit, mit dem eine Anwendung auf die Ticket-Methode zugreifen kann. Diese Klasse kann nicht geerbt werden.
Namespace: System.Web.Security
Assembly: System.Web (in system.web.dll)
Syntax
'Declaration
Public NotInheritable Class PassportIdentity
Implements IIdentity, IDisposable
'Usage
Dim instance As PassportIdentity
public sealed class PassportIdentity : IIdentity, IDisposable
public ref class PassportIdentity sealed : IIdentity, IDisposable
public final class PassportIdentity implements IIdentity, IDisposable
public final class PassportIdentity implements IIdentity, IDisposable
Hinweise
Wenn Sie die .NET Passport-Klassen und -Methoden verwenden möchten, müssen Sie das Passport SDK installieren. Passport SDK, Version 1.4, wird unterstützt, aber nicht empfohlen. Passport SDK, Version 2.1, wird unterstützt und empfohlen. Sie können das Passport SDK von https://www.microsoft.com/net/downloads.asp. downloaden.
Weitere Informationen über Passport-Authentifizierung finden Sie unter Passport-Authentifizierungsanbieter.
Hinweis
In einigen Methoden dieser Klasse verfügt die entsprechende Passport-Methode über optionale Parameter. Bei einer Passport-Methode mit optionalen Ganzahl- und booleschen Parametern können Sie "–1" übergeben, um anzuzeigen, dass Passport den Standardwert verwenden soll. Wenn eine Passport-Methode über optionale Zeichenfolgenparameter verfügt, können Sie NULL (Nothing in Visual Basic) übergeben, um anzuzeigen, dass Passport den Standardwert verwenden soll. Wenn ein Parameter einen dieser Standardwerte annehmen kann, wird dies in der Parameterbeschreibung vermerkt.
Hinweis zu Windows XP Home Edition, Windows XP Professional x64 Edition, Windows Server 2003: Nur Passport SDK, Version 2.1, wird unterstützt.

<!--
This example demonstrates implementing the soft sign-in authentication approach.
In order for the example to work, the following requirements must be met.
You can find details on these requirements in the Passport SDK documentation.
1. You must modify the Web.config file associated with this page so that
authentication mode is set to "Passport".
2. You must have the Passport SDK installed.
3. You must have a Passport Site ID for the site where your page resides.
If your Site ID is in the PREP environment, you will also need a PREP Passport.
4. You must have installed the encryption key you received after registering your
site and receiving a site ID.
5. You must have the Passport Manager object settings correctly configured for your site.
