Examples
The following example creates a System.Security.SecurityElement, populates its attributes, and uses FromXml to transfer this information to an instance of 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())
Remarks
The FromXml method reconstructs a WebPermission from an XML encoding that is defined by the SecurityElement class.
Use the ToXml method to XML-encode the WebPermission, including state information.
