Opmerkingen

De TraceSection klasse biedt een manier om programmatisch toegang te krijgen tot en de inhoud van de sectie met configuratiebestanden trace te wijzigen. De sectie trace configureert de ASP.NET traceringsfunctionaliteit en bepaalt hoe traceringsresultaten worden verzameld, opgeslagen en weergegeven.

Wanneer tracering is ingeschakeld, genereert elke paginaaanvraag traceringsberichten die kunnen worden toegevoegd aan de pagina-uitvoer of die in een toepassingstraceringslogboek kunnen worden opgeslagen. U kunt de ASP.NET trace viewer (Trace.axd) gebruiken om de inhoud van het traceringslogboek weer te geven.
