Comentarios

La TraceSection clase proporciona una manera de obtener acceso mediante programación y modificar el contenido de la sección del archivo trace de configuración. La trace sección configura la funcionalidad de seguimiento ASP.NET y controla cómo se recopilan, almacenan y muestran los resultados del seguimiento.

Cuando se habilita el seguimiento, cada solicitud de página genera mensajes de seguimiento que se pueden anexar a la salida de la página o almacenarse en un registro de seguimiento de la aplicación. Puede usar el visor de seguimiento de ASP.NET (Trace.axd) para ver el contenido del registro de seguimiento.
