CodeAccessPermission.ToXml Méthode

Définition

Espace de noms:

System.Security

Assembly:

System.Security.Permissions.dll

Paquet:

System.Security.Permissions v8.0.0

Source:

CodeAccessPermission.cs

En cas de substitution dans une classe dérivée, crée un encodage XML de l’objet de sécurité et de son état actuel.

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

Retours

SecurityElement

Encodage XML de l’objet de sécurité, y compris les informations d’état éventuelles.

Implémente

ToXml()

Exemples

L’exemple de code suivant montre un remplacement de la ToXml méthode. Cet exemple de code fait partie d’un exemple plus grand fourni pour la CodeAccessPermission classe .

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

Remarques

Le code personnalisé qui étend les objets de sécurité doit implémenter les ToXml méthodes et FromXml pour rendre les objets sécurisés.

Notes pour les responsables de l’implémentation

Vous devez remplacer cette méthode dans une classe dérivée.
