Domandina sui cookies

[Daniele80]

ciao,

io devo fare un controllo e se faccio cosi:
if Request.Cookies("nome_cookie")("campo")="ok" then

ricevo errore per ora ho risolto facendo cosi:
if Request.Cookies("nome_cookie") Is Nothing then

però mi piaerebbe capire come confrontare un singolo campo del cookie invece di vederne l'esistenza.


grazie

If Not Request.Cookies("nome_cookie") Is Nothing AndAlso Request.Cookies("nome_cookie")("campo") = "ok" Then

se metto
If Request.Cookies("nosilence")("Votato") = "" Then

ricevo questo errore:
