CodeAccessPermission.ToXml Metodo

Definizione

Quando sottoposto a override in una classe derivata, crea una codifica XML dell'oggetto di sicurezza e del relativo stato corrente.When overridden in a derived class, creates an XML encoding of the security object and its current state.

public:
 abstract System::Security::SecurityElement ^ ToXml();
public abstract System.Security.SecurityElement ToXml ();
abstract member ToXml : unit -> System.Security.SecurityElement
Public MustOverride Function ToXml () As SecurityElement

Restituisce

Codifica XML dell'oggetto di sicurezza, che include le eventuali informazioni sullo stato.An XML encoding of the security object, including any state information.

Esempi

Nell'esempio di codice riportato di seguito viene illustrato un override del metodo ToXml.The following code example shows an override of the ToXml method. Questo esempio di codice fa parte di un esempio più ampio fornito per la classe CodeAccessPermission.This code example is part of a larger example provided for the CodeAccessPermission class.

public:
   virtual SecurityElement^ ToXml() override
   {
      // Use the SecurityElement class to encode the permission to XML.
      SecurityElement^ esd = gcnew SecurityElement( "IPermission" );
      String^ name = NameIdPermission::typeid->AssemblyQualifiedName;
      esd->AddAttribute( "class", name );
      esd->AddAttribute( "version", "1.0" );
      
      // The following code for unrestricted permission is only included as an example for
      // permissions that allow the unrestricted state. It is of no value for this permission.
      if ( m_Unrestricted )
      {
         esd->AddAttribute( "Unrestricted", true.ToString() );
      }

      if ( m_Name != nullptr )
      {
         esd->AddAttribute( "Name", m_Name );
      }

      return esd;
   }
public override SecurityElement ToXml()
{
    // Use the SecurityElement class to encode the permission to XML.
    SecurityElement esd = new SecurityElement("IPermission");
    String name = typeof( NameIdPermission).AssemblyQualifiedName;
    esd.AddAttribute("class", name);
    esd.AddAttribute("version", "1.0");

    // The following code for unrestricted permission is only included as an example for
    // permissions that allow the unrestricted state. It is of no value for this permission.
    if (m_Unrestricted)
    {
        esd.AddAttribute("Unrestricted", true.ToString());
    }
    if (m_Name != null) esd.AddAttribute( "Name", m_Name );
    return esd;
}
    Public Overrides Function ToXml() As SecurityElement
        ' Use the SecurityElement class to encode the permission to XML.
        Dim esd As New SecurityElement("IPermission")

        Dim name As String = GetType(NameIdPermission).AssemblyQualifiedName
        esd.AddAttribute("class", name)
        esd.AddAttribute("version", "1.0")

        ' The following code for unrestricted permission is only included as an example for
        ' permissions that allow the unrestricted state. It is of no value for this permission.
        If m_Unrestricted Then
            esd.AddAttribute("Unrestricted", True.ToString())
        End If
        If Not (m_Name Is Nothing) Then
            esd.AddAttribute("Name", m_Name)
        End If
        Return esd
    End Function 'ToXml
End Class

Commenti

Il codice personalizzato che estende gli oggetti di sicurezza deve implementare i metodi ToXml e FromXml per rendere gli oggetti codificabili per la sicurezza.Custom code that extends security objects needs to implement the ToXml and FromXml methods to make the objects security-encodable.

Note per gli eredi
