Beispiele

Das folgende Codebeispiel zeigt eine Überschreibung der ToXml -Methode. Dieses Codebeispiel ist Teil eines größeren Beispiels, das für die CodeAccessPermission-Klasse bereitgestellt wird.

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

Hinweise

Benutzerdefinierter Code, der Sicherheitsobjekte erweitert, muss die ToXml Methoden und FromXml implementieren, um die Objekte sicher zu machen.

Hinweise für Ausführende

Sie müssen diese Methode in einer abgeleiteten Klasse überschreiben.
