Upload af flere billeder
Hej eksperterJeg forsøger mig med at lade en bruger uploade flere filer.
Nedenfor har I min kode. Det der undrer mig er, at Request.Files.Count antager værdien "0", uanset hvor mange filer jeg angiver til upload.
Kan I forklare hvorfor det sker?
Jeg er først lige begyndt at indarbejde klient side scripts i mine arbejder, så det kan sagtens være her fejlen ligger.
På forhånd tak.
