Esempio
Nell'esempio seguente viene creato un System.Security.SecurityElementoggetto , viene popolato i relativi attributi e viene FromXml usato per trasferire queste informazioni in un'istanza di WebPermission.
// Create a WebPermission without permission on the protected resource
WebPermission^ myWebPermission1 = gcnew WebPermission( PermissionState::None );
// Create a SecurityElement by calling the ToXml method on the WebPermission
// instance and display its attributes (which hold the XML encoding of
// the WebPermission).
Console::WriteLine( "Attributes and Values of the WebPermission are:" );
myWebPermission1->ToXml();
// Create another WebPermission with no permission on the protected resource
WebPermission^ myWebPermission2 = gcnew WebPermission( PermissionState::None );
//Converts the new WebPermission from XML using myWebPermission1.
myWebPermission2->FromXml( myWebPermission1->ToXml() );
// Create a WebPermission without permission on the protected resource.
WebPermission myWebPermission1 = new WebPermission(PermissionState.None);
// Create a SecurityElement by calling the ToXml method on the WebPermission
// instance and display its attributes (which hold the XML encoding of
// the WebPermission).
Console.WriteLine("Attributes and Values of the WebPermission are :");
myWebPermission1.ToXml().ToString();
// Create another WebPermission with no permission on the protected resource.
WebPermission myWebPermission2 = new WebPermission(PermissionState.None);
//Converts the new WebPermission from XML using myWebPermission1.
myWebPermission2.FromXml(myWebPermission1.ToXml());
' Create a WebPermission without permission on the protected resource.
Dim myWebPermission1 As New WebPermission(PermissionState.None)
' Create a SecurityElement by calling the ToXml method on the WebPermission
' instance and display its attributes (which hold the XML encoding of
' the WebPermission).
Console.WriteLine("Attributes and Values of the WebPermission are :")
myWebPermission1.ToXml().ToString()
' Create another WebPermission with no permission on the protected resource.
Dim myWebPermission2 As New WebPermission(PermissionState.None)
'Converts the new WebPermission from XML using myWebPermission1.
myWebPermission2.FromXml(myWebPermission1.ToXml())
Commenti
Il FromXml metodo ricostruisce un WebPermission oggetto da una codifica XML definita dalla SecurityElement classe .
Usare il ToXml metodo per codificare XML , incluse le WebPermissioninformazioni sullo stato.
