次の例では、 を System.Security.SecurityElement作成し、その属性を設定し、 を使用 FromXml して この情報を の WebPermissionインスタンスに転送します。

// 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

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

Console.WriteLine("Attributes and Values of the WebPermission are :")
myWebPermission1.ToXml().ToString()

' Create another WebPermission with no permission on the protected resource.

'Converts the new WebPermission from XML using myWebPermission1.
myWebPermission2.FromXml(myWebPermission1.ToXml())
