Ciao a tutti, tempo fa avevo trovato un esplora risorse carino... funziona tutto correttamente ma ho notato che quando apro un file (cliccando sul link del file) mi genera il file e, in fondo al file, trovo la pagina HTML dal <!DOCTYPE fino al </HTML>
((
Avevo provato a piazzare un
Response.End();
col risultato che mi vengono visualizzati tutti i caratteri del file nella pagina web!
