Hinweise

Verwenden Sie diese Eigenschaft, um anzugeben, wie der Browser Formulardaten zur Verarbeitung an den Server sendet. Die beiden gängigen Methoden, die von allen Browsern unterstützt werden, sind GET und POST.

Achtung

Sie können den Standardwert dieser Eigenschaft überschreiben und die GET -Methode anstelle von POSTverwenden. Da GET Anforderungen jedoch begrenzt sind, wie viele Daten sie enthalten können, kann die Verwendung der GET -Methode in einigen Fällen dazu führen, dass die vom ASP.NET Seitenframework bereitgestellten Postback- und Zustandsverwaltungsfunktionen fehlschlagen.
